blenderusdz's Introduction

Blender UDSZ file import/export add-on

USDZ file import and export plugin for Blender, that provides a simple method of importing and exporting models used with Augmented Reality applications.

Installation

Download io_export_usdz.zip file from the root of this repository.
Open Blender 2.8 and Go to edit -> User Preferences...
In User Preferences select Add-ons on the left hand menu and then select the Install button on the top right side of the window.
Navigate to and select the downloaded zip file from step 1.
Select the check mark next to Import-Export: UDSZ format to activate the plugin.

Usage

Always be sure to save your work before using this tool. This tool will attempt to export the currently selected objects in the blender scene. The tool can be found in blender under File -> Export -> USDZ (.usdz) When selected the add-on will present the usual file export window for where to export the usdz file along with some options on the left side tool bar. Depending on which options are selected and the size and complexity of the selected objects could affect the amount of time it takes to export a usdz file.

Add-on Options

Import Options

Import Materials - By selecting this option, the add-on will attempt to import materials associated with objects.

Export Options

Export Materials - The exporter will export object materials as USD Principled shader materials which share many of the same properties as the Principled BSDF shader for Eevee and Cycles in Blender. Mix and Add shader nodes are not supported yet in this add-on.

Export Animations - When selected, the active object/bone animation will be exported to the usdz file. Currently any animations are baked per-frame.

Bake Textures - When enabled, any textures associated with materials will be baked out to image files that will be bundled into the usdz file. Currently the add-on will automatically switch to Cycles to bake images which could take a significant amount of time. This option is ignored if Export Materials is unchecked.

Bake AO - This options bakes ambient occlusion textures that are applied to the USD Principled shader materials in the usdz file. Activating this option can add a significant amount of time to export. This option is ignored if Export Materials is unchecked.

Samples - The number of samples used in baking the ambient occlusion textures. A higher number generates higher quality occlusion textures with added time to export. This option is ignored if either Export Materials or Bake AO options are unchecked.

Scale - This value is used to scale the objects exported to the usdz file.

Use Usdz Converter Tool - By selecting this option, the add-on will export a usda file that will be converted to usdz by the external Usdz Converter Tool bundled with Xcode. Note that the Usdz Converter has been deprecated from the current version of Xcode and this option will no longer work.

Notes

This add-on has only been tested to work on Mac-OS and there are no guarantees that it will work on Windows or Linux.

The generated binary usd file used in the exported usdz file could potentially be incompatible to some augmented reality applications, in these cases it is recommend to export the text version of a usd file by adding the ".usda" extension to the exported file name. Then use the usdconvert tool in usdpython to generate the final usdz file.

The import functionality is currently limited to simple static models with no animations.

Misnomer in project readme

The project readme states that this is for the “UDSZ” format, which does not match the repository name, “BlenderUSDZ.”

Obviously a typo, but a rather dismarketing one to be on the front page of the addon. 🤭🙃

Mac OSX Big Sur. 11.5.2

Most of my future work will require Y-up orientation and I will need to switch platforms if Blender unable to export to USDZ. I am hoping you are still working on this Add-on.

For Windows

Is there any chance that usdz exporting would work on Windows in near future?

Addon hangs Blender when importing a zero point dummy mesh

Example:

https://ambientcg.com/view?id=PavingStones115A
Download and rename as usdz

Likely cause:

def Mesh "ambientCG_Dummy_Delete_Me"
{
    int[] faceVertexCounts = []
    int[] faceVertexIndices = []
    rel material:binding = </ambientCG_Material_PavingStones115A_1K_JPG>
    point3f[] points = []
    texCoord2f[] primvars:st = []
}

Example that doesn't hang:

uv mapping not set properly

trying to load usdz from iphone app polycam (lidar scanning), textures are loaded and mesh but the UV map node connected to vector just says st and everything blank..
..removing or changing to uv mapping nothing works, so it's either not set at the source properly or there was some problem while importing..

Texture Maps not exporting

When I use the exporter with a material that has a texture map attached. It either exports with no material or the file wont be recognized by XCode or Apple's previewer. I assumed it was my asset, but when I downloaded the USDZ examples off Apple's website. They imported (using your importer) with the materials, but they do not export with the material. It only seems to work if I remove the texture maps and use the color sliders, but this wont work for the models I am trying to work on as I need the texture maps to export too. I tested this with using USDA and the USDZ converter, It did not work either.

Exporting model with animation/rig results in error

Tried exporting with and without the armature, both results in an error. Issue appears to persist on both Windows and Mac. Is there any fix for this?

Export settings have no texture or material output options.

When I attempt to export a model the settings are totally blank. No options at all. SO the resulting used export is just the mesh. Like an Obj. Nothing else.

deleting objects throws exception

Hi, this plugin is great, thanks for making it.
In Blender 2.82, I make a scene with animations, export to USDZ all works OK.
If I go back and delete an object,save, then export it throws an exception:

Export as component USDZ model (containing separate parts)

Hi,

I am trying to have separated parts in my model to be able to show/hide some parts (more described here). I found that I need to access modelEntity.children property and there should be many children for each parts. But for me it has only 1 child. How can I export model to have many parts/children? I am new in Blender so I don't know if I should keep each part in collection or how to set hierarchy.

Thanks for help

UPDATED:: Installed now, but now import errors

n00b here, but what file am supposed to install exactly?

The instructions say to instal "io_export_usdz.zip", but all I see are files called "BlenderUSDZ-master.zip" and "io_scene_usdz.zip". Following through with the instructions anyway produces expected results of nothing showing up in add-ons menu to add on.

Where do I go from here? Is this no longer an operational plugin?

Importing USDZ Model Bug

I imported the Toy Robot Vintage example from Apple, I am getting this:

Is it because of the animation data that comes with the robot?

NASA Globe not importing

Is this plugin still working for blender 2.90?

NASA hosts a rendering of earth: https://solarsystem.nasa.gov/resources/2393/earth-3d-model/

But in blender all that's visible is:

Exporting Blender animation to USDZ

Great converter. Thanks for building this. When I try to export a blender animation with key frames, I can only get the animation to export a still object at the position of the play head. Am I missing a step in conversion process or setting up animation in Blender incorrectly? Thanks!

Exporting light/emissive textures

Hi there,

I was wondering if there's support for exporting emissive textures for the purpose of making a lamp/light?

So far I haven't been able to get it to work with Principled BDSF or Emissive textures in Blender.

Thanks for your help

I have questions about the method here:

Not to be critical, I'm sure this is a useful plugin but it seems there are two other (better?) methods this could be done:

Blender can now (2.82) create USD files. You could then use the usdzip utility to create a usdz file
USD now has Python3 bindings (in fact if you used the NVidia distribution had them for a while so could use that to write out files

Again, not saying this isn't a nice addon, but I'd recommend moving to one of the above methods rather than writing out files by hand. Seems to be re-inventing the wheel, or at least if the api changes will not work.

files only allowed to have one dot char

the importer crashes if a file name contains more than one dot char

Unable to Install in Blender 2.93

Hello, I am unable to install this through Blender 2.93. After selecting the BlenderUSDZ-master.zip, I see Blender processing the install but it never appears in the list of addons. Has anyone else had this issue? Do I need to revert back to 2.8 to use this addon?
Thanks

Baking Textures Suggestion and AO query

Hi. Could you make the baking of the textures linked to the material instead of objects. Right now it exports texture map for every objects even if they have the same material. This is the gramaphone I downloaded from apple website. I imported and exported it again. Also how do I input custom AO map from blender. I dont see any AO Map when I import the USDZ File.

Bake Texture Option is slightly vague

From my first test of the addon, I noticed that if I did not enable "Bake Texture" option, the Image Texture that I assign to Material does not actually get exported out. It will simply have Material with no texture.

So I need to use Bake Image Texture, specify the (optimized) size and only then I am getting USDZ with material + texture.

It might be slightly confusing for user however. Maybe they just want to export the Material + Texture as is, and not realizing "Bake Texture".

Non-Colour Data issue on import

I got an error when importing also textures along with an usdz file.
I was able to fix the issue on a couple of lines of code and now it works correctly for me on 2.83.
Here the link to the fixed addon if someone else needs this: http://u.pc.cd/khvrtalK

Does not work with Transparency or Alpha PNG?

Hi I tested the USDZ export, so far so good! It seems to be working for simple material, but if I use transparency shader or PNG with alpha, it does not seem to work:

Any idea on this?

UDSZ Import?

Is it possible for this addon to import the latest version of USDZ (circa Object Capture API)?

Running in headless mode documentation

Hello, I'm planning to use the file to import usdz to other file types via purely python script and CL, I was wondering if that would be possible with the use of this library?

Bug when exporting USDZ with baking ambient occlusion option?

I was making a video on this addon and finding a bug when I tried to export out a simple Duck mesh + texture and bake the AO.

I wonder if this is something to do with Mesh not selected or not inside expected Collection Set or something.

We need probably option to export Selected Objects only or everything in the scene, without having to actually select them manually.

Doesnt work for a few usdz files

I tried it on a bunch of usdz files provided by apple APIs, but there in no geometry I can see in blender.

This usdz file Toy drummer usdz for example doesnt work.
This is with blender 3.2 .
Any thoughts on how this can be fixed?

Selectively call usdcat instead of xcrun usdconvert

It seems your dependency to macOS and installed XCode with usdconvert is because you use the wrong (meaning not official) tool to convert from .usda to .usdc

Pixar has the python script usdcat to translate between USDA and USDC.
And this not only is installed on macOS, but can be installed on Linux and Windows as well.

There is a binary release of the USD Tools version 19.11 for Windows under Github VictorYudin

Importer only partially imports ISS model

Hi there. Thanks for the awesome plug-in. I tried it on this model, however, and it only imported about a third of the model:

Import of *.usdz from iOS app "Capture" doesnt work

Hello,

I made test 3D scan of my face using the Capture app on iphone xs (https://apps.apple.com/us/app/capture-3d-scan-anything/id1444183458) which saves the 3D scans as *.usdz files.
I sent it to myself via email from the app and tried to import into Blender using your script, but theres nothing imported in the scene.
In Blender console it says "No usdc file found"

I know usdz is just zip file with other usd* files. so i tried to manually export the *.usdc file from the usdz and tried also to import directly *.usdc file, but nothing is imported, and with *.usdc theres no message in the log at all.

Then as last thing i tried to "zip" the exported usdc file again with zero compression (and putting the usdc file at the root of the zip), and renamed it to *.usdz. That actually imported something into Blender, i see vertex and face counts, but nothing really visible on screen and the location of the imported model was waay out somewhere - see first screenshot.
I moved the whole object to 0 0 0 and now i see single vertex like object in the middle of the screen which i tried to resize, but doenst help, it stays like that.

Capture is one of the fully free 3D scan apps afaik (for now and hopefully forever) supporting the TrueDepth camera on newer iphones so it would be really cool if this was fixed :)

BR,
Adam

The auto smooth setting did not work for now?

Can't Find Zip File

I am a little confused as I cannot find the file mentioned (io_export_usdz.zip ). I can find io_scene_usdz.zip but not the export variant.
I click on Code and do not see that particular file name.

Hi, this plugin is great, thanks for making it. In Blender 2.82, I make a scene with animations, export to USDZ all works OK. If I go back and delete an object,save, then export it throws an exception:
