    • - *
  • aiAnimation::mDuration may be -1. Assimp determines the length - * of the animation automatically in this case as the length of - * the longest animation channel.
    • - *
  • aiMesh::mBitangents may be nullptr if tangents and normals are - * given. In this case bitangents are computed as the cross product - * between normal and tangent.

  • There needn't be a material. If none is there a default material - * is generated.
