Exporting a model with multiple materials doesn't seem to maintain correct normals #13

Closed bartteunis closed 2 years ago

This is when splitting by material first. The resulting meshes seem to loose normal info

Normal info can't be lost when there is no need to split by material to begin with. Change the vertex buffer export code to loop through a Blender 'MESH' object's materials first, then through the mesh's polygons that use that material (use MeshPolygon.material_index). Doing it this way should preserve the normal data.
