Every half circle (π) the rotation values change, in a wrong way
This need further investigation, since right now i have no idea where the error come from

I followed your wiki, fisrt compile the external modules, it's all ok.But when compile the engine itself, there is too many errors:

It seems cannot find the standark lib of cpp, but i'm not famililar with VS.
There is also some errors like syntax error:

There's a part of code that's not done right:
cleanup_meshes() is called in two different parts of the code: one in a thread and one into another thread, this probably can lead to errors and crashes.
The cleanup of the meshes vector must be checked and fixed to be safe with other parts of code that use this vector.

Here you have managed to link external repositories to your library folder. I would like to do the same thing too, could you tell me how you did it?

Hello, i'm comeback again : )

Nowadays, i'm studying the light model.
Your engine are using the plane lights with a single light source, is right?
But what the principle to compute the shadow, any document will be helpful, thank you very much!

The parent-child relative rotation is broken, and must be fixed as soon as possible

f:\projects\github\scrapengine\external\assimp\include\assimp\defs.h(53): fatal error C1083: Cannot open include file: 'assimp/config.h': No such file or directory

Doesn't compile out of the box for debug or release
Can't bulid the sample for obvious reasons - no engine

I'm a newbie to vulkan, i read your code, but there is so many jump between the functions. The most one i cannot understand is that how to render multiple objects to one image, such as skybox,ball and the light.

The memory allocation is self-done and could not be perfect;
It's better to use GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator

The engine will be ported to use VulkanMemoryAllocator soon

Premake can allow you to create setup for VS, CMake and more easily.

The engine is starting to have way too many includes, everything (possible) should be moved to forward declaration also for a fast compilation
