I know 3d animated models support is one of the weakness in raylib but no plans to integrate Assimp. Anyway, I stopped searching for a way to load al of this properly, and I will stick to the good old phong material for my game, I really want those DDS textures, since it really makes a difference in texture loading time (like 8 times faster than PNG/JPG). An informal summary is: do whatever you want, but include Assimp's license text with your product - It comes with a GPU-friendly binary (compared to something like Wavefront OBJ which is very slow), and you can even have the textures separately if you choose the "glTF Separate" format when you export it. This project exists thanks to all the people who contribute. You signed in with another tab or window. I would like to know if the assimp FBX loader does supports PBR materials. glTF is a standard file format for three-dimensional scenes and models. This update is huge and replaces OpenGL with DX12 and Vulkan using Nvidia's NVRHI API and adds support for glTF 2 models and animations. It supports more than 40 file formats for import and a growing selection of file formats for export. glTF 2.0 uses a single texture that contains: metallic on the blue channel, roughness on the green.

You can see this here: https://github.com/assimp/assimp/blob/master/include/assimp/pbrmaterial.h#L57, The albedo texture (or base color) is aiTextureType_DIFFUSE, (the non-pbr specific stuff seems to be the same naming). Note - some file formats (such as 3DS, ASE) export a "target point" - the point a spot light is looking at (it can even be animated). Please reply Thank you in advance. but this extra complexity is needed since Assimp aims at supporting a wide range of file formats). Assimp importers mostly support big-endian platforms, which define the AI_BUILD_BIG_ENDIAN constant. It supports more than 40 file formats for import and a growing selection of file formats for export. If you think you found a bug, please open an issue on Github.
