Models loaded with Assimp have messed up UVs/normals

Question

I've been trying to use Assimp to load models and so far I got it to load a few obj models, but all of them have messed up UVs (and maybe normals).

Here's what it looks like :

I tried several combinations of Assimp's loading flags, but to no avail.

Here are the used flags :

const aiScene* scene = importer.ReadFile(path, aiProcess_Triangulate | aiProcess_FlipUVs|aiProcess_GenSmoothNormals|aiProcess_ImproveCacheLocality|aiProcess_FixInfacingNormals|aiProcess_FindDegenerates|aiProcess_FindInvalidData|aiProcess_GenUVCoords|aiProcess_TransformUVCoords);

I'm only loading already triangulated (with Blender) obj models with no submeshes.

Thanks in advance for any help.

Answer 1

The problem actually didn't come from Assimp but from the way I internally stored assimp's UVs. I didn't take into account the fact that there can be no UVs some times and thus, I had random values when there were none.
