I'm getting an error when converting my FBX file. Not much information to give

Loading source file...
Triangulating FbxLine geometry

I get the window fbx-conv-win32.exe has stopped working dialog popping up.

The FBX file is converted from 3ds Max 2012.

I can PM the link of the file to the developer who is handling this issue.

I created a simple cube in Cinema 4D, exported it to fbx and tried to convert it. However, the converter crashes.

I uploaded the fbx file here: http://pastebin.com/0paTdvQE

Could you please check why it crashes?

Introduction. The described below is connected to combination of logic of BaseAnimationController and fbx-converter. So one have to decide which part would be fixed. Currently I've made a quick fix of fbx-conv part to solve the issue.

In complex skinning animation transition could lead to a very strange result. For example there are two animations where the hero stands just close (but different) poses. In one animation it move hands, in another - head. During transition (as it was in my case) the leg start to move to the side during the transition time and then immediately returns to the correct position exactly when the transitions was finished.

BaseAnimationController has the method:

/** Apply two animations, blending the second onto to first using weight. */
protected void applyAnimations(final Animation anim1, final float time1, final Animation anim2, final float time2, final float weight) {
    if (anim2 == null || weight == 0.f)
        applyAnimation(anim1, time1);
    else if (anim1 == null || weight == 1.f)
        applyAnimation(anim2, time2);
    else if (applying)
        throw new GdxRuntimeException("Call end() first");
    else {
        begin();
        apply(anim1, time1, 1.f);
        apply(anim2, time2, weight);
        end();
    }
}

where in the last lines we apply the previous animation with weight 1, and then directly apply new (current) animation with specific weight. Under the hood the method make linear interpolation of everything like prev_(1-weight) + curr_weight.

Keep in mind, that we first apply previous animation at the full weight, and only then reduce it weight to (1-weight) when applying the current animation. So, if some bones will not be present in the current animation, but will present in prev animation we will have very strange results (like described in the beginning).

What's the deal? We could just add the correct initial values of all bones to the first animation key in Blender (or whatever) to all animations. Then all animations will have exactly the same amount of bones in use.

This it true, but fbx-conv bring another surprise. In FbxConverter.h, line 633 we have

// Only add keyframes really needed
addKeyframes(nodeAnim, frames);
if (nodeAnim->rotate || nodeAnim->scale || nodeAnim->translate)
animation->nodeAnimations.push_back(nodeAnim);
else
delete nodeAnim;

So, if the animation does not use the bone, and if the initial bone state is zero (no rotation, transition, etc.) it will not be included in the g3db file. So, disregarding we have added all initial bone states in Blender, we will have very funny transitions.

It take some time for me to understand the problem. I have fixed it by removing this check in fbx-conv and leaving only one line:

animation->nodeAnimations.push_back(nodeAnim);

disregarding if the bone have some transformation.

Another, probably more proper solution, will be initially apply prev and curr animation with (1-weight) and (weight) coefficients. Or apply some "zero" bone to the transformations, which are present in prev, but absent in curr animations. Just to scale them down to (1-weight).

The latest version of fbx-conv-lin64 is correctly creating the parts under each node. Thank you xoppa your work is greatly appreciated.

There is one more issue that seems to be occurring. The models seem to be triangulating the mesh geometry for every other mesh.

....

These are box shapes, so the polygons count should be 12 and indices 36. Here is the FBX file i am using:

In G3DJ, How do you map bone index (in the array) to bone name? I can't find this anywhere

When using a release version it throws Segmentation Fault when converting a file.
When using a debug version it converts fine but the problem is in loading it in libgdx.

Hey guys I'm a beginner at libgdx and I'm having an annoying problem.
I'm developing a project that needs to import a building, which fbx file is very big, but the problem is that when I try to convert the fbx, it keeps always having errors saying "Skipping geometry without material", because the model doesn't have materials, I know that. And if I use a smaller model it gives a lot o warnings because of the number of vertices, and when i run the app it doesn't show the model, it recognises that it exists, the number of nodes, meshes but the materials stays as null as expected, shows only a black screen.
How can i convert the model? Or the model really needs to have materials?

The models are here:https://drive.google.com/folderview?id=0B__hwerDSna6UlAtMmxWV3hoQjg&usp=sharing

Hi,

First of all, congratulations for your work and the converter, I think it is great.

After that, I have to say that I am new to libgdx and, of course, using fbx-conv. In my first steps I have converted some sample models without any problems. However, just now I am trying to convert to g3dj/g3db a FBX model made with 3ds max (I did not make the model, the designer send it to me) and I am having an error and a pop up dialog window error just saying:
"fbx-conv-win32.exe has encountered a problem and needs to close"

NOTE: Full output is at the end if the issue.

I have tell the designer the considerations for the fbx model that I have seen here (https://github.com/libgdx/libgdx/wiki/Importing-Blender-models-in-LibGDX), although this considerations are for blender. Considerations I have tell him when exporting to FBX are:

• Select all and only those options (e.g. nodes and animations) you want to actually include. Don't include your camera, lights, etc.
• Set key frame interpolation to linear (from the default bezier interpolation) for avoiding big size file.

However, I get the above error, and none information about what the problem could be. So, as developer, how could I get more information about the problem for telling to the designer? I do not know if the problem is that he did not follow the considerations, a program problem, etc.

I also have seen in this issue (#38) that there is a file size consideration, so that the model should not exceed, but I have not found this size limit in the information. Is there a real size limit? In that case, which one?

On the other part, from this other issue (#39) I understand that it is not recommended to use any fbx extension, but only the default autodesk fbx converter without any "extra" for avoiding possible errors.

There is any other consideration to take into account? I think it would be interesting to join all this information, and, if possible, to add also restrictions for 3ds max and maya users for taking into account when exporting the fbx models.

On the other hand, I think it could be useful also to have more information about the errors so that I could tell the designer to reduce the number of vertices, or to avoid such an extension, or whatever, I do not know if it could be possible.

Thank you very much for your work and time.

Hi,

I found if there is empty indeces node in in my g3db file, it will cause the whole game to be crashed. Not sure if it is possbile to just spit some warning info, and take the empty node as "nothing" and continue?

Reported here http://www.badlogicgames.com/forum/viewtopic.php?f=11&t=16570&sid=573dcda8efadc69ac82dedcaa05c5345. Verified, the executable inside http://libgdx.badlogicgames.com/fbx-conv/fbx-conv.zip is indeed very small and doesn't run.

When I use fbx-conv 0.01.0000 x64 to convert a OBJ into G3DJ the texture material gets opacity value 0 so the model won't be visible (0 for transparent, right?).

If I change the opacity value in G3DJ file to 1 the model becomes visible.

When converting some FBX models the texture coordinates seems to be incorrect when loading the .g3dj file with libgdx 0.9.9. One example is the zombie included in the Autodesk FBXConverter 2013.3 where the coordinates for the Zombie_Diffuse.png texture are incorrect.

When the provided ,fbx file does not exist the program crashes with:

ERROR:    FBX SDK encountered an error: Unknown

Sometimes it is very useful to convert g3dj to g3db, not sure if could add such feature?

I looked for file with project license, also into sources for main application, but did not found any information on it (if there is some information on it already, I'd be happy to get some pointer to it, because I wasn't able to find it).

I'd like to package this to be available to users of Linux distribution I use, and specifying valid license in package is requirement here.

See libgdx/libgdx#1346

fbx-conv-lin64 does not work on Ubuntu 14.04 (x64):

I have an error:

Looking into the fbx-conv code and their g3dj example files I found an attribute called BLENDINDICES, but no documentation about it and how to use this kind of attribute. Maybe is not yet documented this attribute?

Btw I would be happy to collaborate to help to improve these project. Is there any place to see which issues are pending to solve, or what are the next thing to do in this project?

lvlongdeiMac:fbx-conv lvlong$ ./generate_xcode
'premake4' not found in your path.

but the premake4 has already in the path: "fbx-conv/"

I'm just reading the G3DJ format on the specification page and something caught my attention.

I converted a file from FBX to G3DJ and the following section was on the file

...
"parts": [
{
"meshpartid": "shape1_part1",
"materialid": "unnamed",
"bones": [
{
"node": "bone_1",
"translation": [ 0.988038, 0.000000, 0.263477, 0.000000],
"rotation": [ 0.500000, -0.500000, 0.500000, 0.500000],
"scale": [ 1.000000, 1.000000, 1.000000, 0.000000]
},
...

but reading the 0.1 specification (and also 0.2) I was led to believe the "bones" section is only a list of nodeid's, the actual rotation, location and scale should be on the node referenced by the bones section (and indeed it is, and it have different values listed for those three attributes).

:
{
"meshpartid": <meshpartid>,
"materialid": <materialid>
(, "bones": [(<nodeid> (, <nodeid>))?])?
(, "uvMapping": [(<uvmapping> (, <uvmapping>))?])?
}

The resulting file does open but doesn't animate (I can't right now attest that it "should" animate, as my code can be wrong).

Anyway, here are the original FBX and G3DJ files for reference.

I'm running Debian 7 & fbx-conv version 0.01.0037 x64 (pre-release) using a precompiled binary;
Here is a link to an archive with the objects, and their respective command output's in text format.

Any help is much appreciated!

Often converter drops the last animation frame which leads to animation jitter on looping. The reason is "for" loop over float variable and rounding imperfectness (Fbx.Converter.h, line 612) at the last loop iteration.

Somehow I can not make a pull request. The fast solution is to: replace Fbx.Converter.h, line 612 from:
for (float time = (_itr).second.start; time <= (_itr).second.stop; time += stepSize) {
to:
const float last = (_itr).second.stop + stepSize * 0.5f;
for (float time = (_itr).second.start; time <= last; time += stepSize) {

Afterwards it works.

There are some kinds of animations that cannot be easily replicated with skeletal animations. One such example would be an exploding object, where multiple faces are moving in different directions at once. Some facial expressions are also much easier to create using morph targets.

Since FBX does support morph targets / blend shapes / shape keys, It would be great if support could be added to the fbx-conv tool, with the ultimate goal of also adding support in libgdx core.

I'm having problems building it. I've downloaded FBX SDK 2014 and precompiled binaries. Then, I've opened premake.lua and changed "FBX_SDK_ROOT" for "C:\Program Files\Autodesk\FBX\FBX SDK\2014.1". Finally, double click on generate_vs2010 (i'm usign windows) but it show me the following message

"'premake4' not found in your path. Premake can be downloaded from http://industriousone.com/premake/"

What am I doing wrong?

I have a model exported in Versions 7.1/7.2/7.3 and 7.4 which I converted to g3dx format. I loose all textures while converting. The materials section does not contain a textures array although textures get extracted from the FBX file. If I preview the file in FBX Converter from autodesk it is displayed correct.
Only if I use FBX Version 6 the texture array appears in the g3dx file. So I assume the converter has an issue with version 7 of FBX file format extracting them but not referencing it in the g3dx file.

The model im using has gone through ArchiCAD->Cinema4D->Libgdx.

Some bones that were clearly bones in the original model are not tagged as such on the exported G3DJ. Even if they contain no skinning or animation, they are still helpful as visualization or attach points and force the importer to do guesswork that is not always possible either. Would it be possible somehow to include back this information in the converter?

I've tried with the latest precompiled version on Mac and Windows, and all the models I've tried are loading properly, but not showing at all. Tried compiling it myself on Mac and got the same problem.

Tried with the same models with an old fbx-conv binary I had around, and it worked properly, so something must be wrong with the code and the latest version.

Tried everything with LibGX 1.4.1.

Sorry, I don't know where to ask this question, in the wiki section of fbx-conv there is no documentation, and I don't know exactly how to work with it.
I only know that I should call "fbx-conv" command in command line, for example:
fbx-conv ship.obj
But where should I enter this command? There is no exe file in source.
Any help would be much appreciated.

When exporting my .fbx from Blender, if I choose Version 7.4 the resulting model would always be oriented face down to the ground. The axis settings in Blender have no effect. (The scaling also seems to be a little different from Blender settings, but I'm not sure).

I guess I could rotate the model and scale in-game, but it would be great if this were corrected.
http://www.filedropper.com/woodtower

After conversion of FBX from Blender bone lists of some animations appear to be empty:
...
{
"id": "idle",
"bones": []
},
...

or contain only keyframes for keytime 0.

That didn't happen with couple of months older precompiled binary version.

Hi,
I'm trying FBX conv on FBX models from the www.
Some models are good, some other crash during conversion and I don't figure out why exactly.
I get this file for example : http://tf3dm.com/3d-model/modern-desk-34387.html to convert from FBX, and I got an error in the FbxConverter.h in prefetchMeshes() line 457 :

if (info->elementMaterialCount <= 0) {
log->error(log::eSourceConvertFbxNoMaterial, getGeometryName(geometry));
scene = 0;
break;
}

It seems that the material count is 0, but I don't get why.
I tried to debug it by myself but without any success... sorry for that.

If I can help... let me know !

Thanks.

I tried to locate the prebuilt binaries for linux but could only find what seemed to be for Mac OSX. So I tried to build the project myself on Linux (LinuxMint 16 x86_64) but received the following error:

Linking fbx-conv
../../../../Applications/fbx-sdk/lib/gcc4/x64/debug/libfbxsdk.so: undefined reference to `dlopen'
../../../../Applications/fbx-sdk/lib/gcc4/x64/debug/libfbxsdk.so: undefined reference to `dlclose'
../../../../Applications/fbx-sdk/lib/gcc4/x64/debug/libfbxsdk.so: undefined reference to `dlsym'
collect2: error: ld returned 1 exit status

After searching around, I found this post on stackoverflow which suggests it's gcc's fault.

I edited the build/gmake/fbx-conv.make file and appended the flag -Wl,--no-as-needed flag to the LDFLAGS variable which allowed me to complete the build. The problem is the resulting executable segfaults.

Hi I've got the problem.
I use libgdx and the newest version of fbx-conv to prepare g3db models.
My model's got more indieces
[quote]WARNING: Mesh contains more indices (397440) than the specified maximum (32767)[/quote]
and it looks bad in the game.
I studied fbx-conv code and saw that max value of indieces can change. I don't know why is it that small number.
Anyway could you change it in fbx-conv program or just advice me what to do with that problem?
I tried to add obj model but it's not working good after all.

it's got a blue mark. It's wrong

Converting Autodesk FBX Zombie.fbx, it converts fine. Converting Roger_CharacterFace_Shape.fbx it crashes. When trying to load Zombie.fbx I get the following error:

Hi, I am usign fbx-conv to convert some .obj file. There is a material in this file which has black diffuse color (0,0,0) and some shininess and specular color. But the black diffuse color is not exported into G3DJ file (everything else is there, just the diffuse color is missing). Libgdx renders this as white by default, so that is really not desirable.
If I change the color to 0.001,0.001,0.001, it exports fine and renders good.

After running:

fbx-conv -p -v "path to file"

FBX-conv gives me a warning that there are too many mesh vertices. So I try setting the maximum allowed indices with this command:

fbx-conv -p -v -m 64k "path to file"

It prints the warning again and tells me the max is now "64." If FBX-conv does not accept *k numbers then please do not put them in the help printout. So I ran:

fbx-conv -p -v -m 64000 "path to file"

Now what does it do, it says "Error, maximum vertex count must be between 0 and 32k"
This is annoying, as now I have to go back into my model editor and split up the node.

So in conclusion, please make FBX-conv accept *k numbers, and please make it accept larger vertex counts if possible.

See http://badlogicgames.com/forum/viewtopic.php?f=11&t=18454

I'm not sure if this is an issue with the fbx format or with fbx-conv....

using blender, If you create a rigged model, and dont weight paint some of the meshes on to a deform bone, then export to fbx and convert to g3db.. the unpainted meshes are invisible.

I could see this being useful when creating organic characters and unweighted meshes are probably a mistake and would show up weirdly. But in my case I'm making a spike trap mechanism and I've purposefully left the unanimated portion of the model unpainted

Hey guys! little confused here.
working on a project where I execute from apache/php

exec("/opt/fbxconv/fbx-conv-lin64 -o G3DB '/var/www/#censor#/public_html/#censor#/assets/Uploads/cube2.fbx' '/var/www/#censor#/public_html/#censor#/assets/FBXUploads/FBXUpload_546/mytest.g3db'");

I've tried executing the same command from the terminal with these results:

INFO: FBX to G3Dx converter, version 0.01.0037 x64 (pre-release)
STATUS: Loading source file
WARNING: [Cube] Node uses RrSs mode, transformation might be incorrect

Below is an strace of the application! any help is much appreciated!

Hi! I've made a Qt/GUI for fbx-conv. I want to talk with a developer and if it's ok to publish it on git(on fbx-conv page) so it would be easy to convert.

I created a model in Blender and created an UV map. I created a new texture for the model's material, loaded the normal map into it, changed coordinates to UV and checked "Normal Map" under "Image Sampling" tab. I also went to the "Influence" tab and checked only the "Normal" influence with a value of 1.0.

I exported this model to FBX following the wiki's recomendation of leaving it in Z-UP mode. The conversion worked as normal but when I opened the resulting G3DJ file I noticed this material definition:

"materials": [
{
"id": "Normal",
"diffuse": [ 0.640000, 0.640000, 0.640000],
"specular": [ 0.800000, 0.800000, 0.800000],
"textures": [
{
"id": "Normal",
"filename": "square_normal.png",
"type": "DIFFUSE"
}
]
}
]

The texture is not mapped as a normal map, instead is being mapped as a simple texture mapping.

Is there anything wrong with my setup or is it just a bug? I'm using the commit "550272c0de9168fe01be2f004c8421700c0c5765".

fbx-conv seems to create additional keyframes.

From just 3 keyframes it created about 70+

Everything worked nicely with fbx-sdk 2014.2, but after update to 2014.2.1 I get error:

../../src/readers/FbxConverter.h:596:27: error: ‘class fbxsdk_2014_2_1::FbxScene’ has no member named ‘GetEvaluator’
     animStack->GetScene()->GetEvaluator()->SetContext(animStack);
                            ^

First off, I use the tool "FBX Multi Take" from here:
http://www.turbosquid.com/FullPreview/Index.cfm/ID/701878 (there is a trial somewhere), and the trial version of 3D Studio Max 2010.

The Multi Take tool/plugin allows one to specify more than one animation in the exported FBX file. Out of the box, 3DS Max only supports one!

After exporting the FBX file, I open the file in "Autodesk FBX Converter 2013" (free). Here I can preview the takes, and verify that they work as expected.

After running them through the FBX-conv tool, it finds all the animations, eg. "Walk", "Run", "Attack" and so forth. But when I try to play the animation in LibGDX, it always plays the entire animation (Walk+Run+Attack). Looking at the generated g3dj file, all the animations "keyframes":"keytime" start at 0.000000

the fix for this issue inadvertently broke the windows build: http://libgdx.badlogicgames.com:8080/job/fbx-conv/20/console

Hello, I successfully compiled and tested Animation3DTest from gdx-tests programs. Unfortunately when I copied knight.fbx model from this repo and converted it with "fbx-convert-win32 -f -o G3DJ Knight.fbx", it generated completely different file. It's smaller and contains different data. When I tried to render my version - program stopped for a few second and then displayed only last frame of animation.

Here is version converted by me - https://dl.dropboxusercontent.com/u/12184815/knight.g3dj
Here is correct version - https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests-android/assets/data/g3d/knight.g3dj

I exported fbx file using blender. I have uploaded the blend and fbx files to mediafire and the link is given below:
http://www.mediafire.com/download/2ydfk62giwms1p7/exports.zip

The log is shown below. After the last line, fbx-conv crashes. What is the solution?

I'm sure I'm doing something wrong. I followed the building instructions and this is what I received from the build.

Let me know if more information is needed.

I'm trying to convert the most basic blender model object (FBX) into a G3DB file and using it in-game, but I keep getting a NullPointerException.

Specs:
Linux Ubuntu 14.04 64-bit
fbx-conv v 0.01.0000 x64 (pre-release)
Blender v2.69

Steps to reproduce:

• Open up blender and export the default starting cube as FBX
• Convert FBX file to G3DB: fbx-conv-lin64 file.fbx
• Load new G3DB file in game: Model fileModel = objLoader.loadModel(Gdx.files.internal("file.g3db"));

And fileModel is null.

Output of "fbx-conv-lin64 file.fbx":
INFO: FBX to G3Dx converter, version 0.01.0000 x64 (pre-release)
STATUS: Loading source file
PROGRESS: Import FBX 100.00%

Hope this helps.
