Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? Assimp supports multiple sorts of light sources, including directional, point and spot lights. You automatically get a merged PNG with both metallic and roughness like I said before: If you really wanna have support for FBX files (I know I do; it's a popular format), what you could do, is to have it correctly identify and load the base color and normal map, but then you have to manually load the "PBR" texture somewhere before the render loop starts, and then manually bind the texture and send it as a uniform to the fragment shader before drawing it. claims to be the ofcial documentation,README.mdis usually the most up-to-date list of le formats supported by the library.

However, there are several versions of the FBX format - not all versions are compatible with XNA or MonoGame! Importing 3D models is a great way to get existing content into Neos, whether it's for building environments, objects, avatars or simply for visualizing them. 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? glTF is a standard file format for three-dimensional scenes and models. Please, share your loader that everyone can profit from it! assimp/Fileformats.md at master assimp/assimp GitHub 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. Loads 40+ 3D-file-formats into one unified and clean data structure. glTF - Wikipedia Assimp: assimp - Open Asset Import Library - SourceForge apply. Because there's no well supported standard for PBR materials in model files, Neos' model importer allows using a naming convention to automatically map texture files to the material based on the file naming. Take a look into the https://github.com/assimp/assimp/blob/master/Build.md file. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen?
