The Asset-Importer-Lib Documentation GitHub - riidefi/RiiStudio: Editor for various 3D model formats I would suggest exporting your animations, to a variety of formats and see if any of them give you wrong results (i.e. assimp currently supports the following file formats (note that some loaders lack some features of their formats because some file formats contain data not supported by assimp, some stuff would require so much conversion work that it has not been implemented yet and some (most ) formats lack proper specifications): See the Importer Notes Page for informations, what a specific importer can do and what not. There are generic PBR material properties since Assimp 5.1.0 that work even for non-glTF files: Full list here: https://github.com/assimp/assimp/blob/v5.1.4/include/assimp/material.h#L972, Old answer: (deprecated since Assimp 5.1.0), For GLTF PBR materials you can use the material keys defined in pbrmaterial.h. * Currently limited to non-rigged models\ RiiStudio (as a C++ library) also supports.

It supports more than 40 file formats for import and a growing selection of file formats for export. I'm really disappointed by the lack of PBR support, for something that's used so ubiquitously in I think all AAA games in the last few years. Parabolic, suborbital and ballistic trajectories all follow elliptic paths. I agree with you, loading one texture by hand can be a solution, I did thought about that, but I won't give it a try even if I know it works :) I also thought of something else : Give your object in Blender/Maya a blinn or phong material, then use the regular channels for albedo and normal map, but for textures like metallic and roughness, you can put them in the transparency and emissive color channels respectively. See the Extending the library page for more information. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. For example 3D scans usually look better with Unlit/PBR Emissive material, otherwise the lighting is applied "twice", leading to a very muddy look. glTF 2.0 uses a single texture that contains: metallic on the blue channel, roughness on the green. assimp export <model> <out> | Fig http://assimp.sourceforge.net/main_features_formats.html.

The library is not designed for speed, it is primarily useful for importing assets from various sources once and storing it in a engine-specific format for easy and fast every-day-loading. And also want to fuse multiple FBX file into one single FBX. Assimp. So there's no better alternative than getting aiTextureType_UNKNOWN (or most likely AI_MATKEY_GLTF_PBRMETALLICROUGHNESS_METALLICROUGHNESS_TEXTURE) since the mettalic and roughness textures are specified in the same material property metallicRoughnessTexture in the gltf?
