Exporting materials #16

Closed changfali closed 2 years ago

changfali commented 2 years ago

I get same issue as Issues10: An error "index 0 is out of bounds for axis 1 with size 0" occurred while exporting the material. vertices, face_vertices, texturecoords, face_texturecoords = loadmesh_and_checkuv(mesh_fpath, out_dir) This code gets the shape of the variables texturecoords and face_texturecoords are both (0,0). Why？

I load meshfpath using your code: import igl vertices, texturecoords, , face_vertices, facetexturecoords, = igl.read_obj('./exp_iron_stage2/xmen/mesh_and_materials_50000/mesh.obj', dtype="float32") print(vertices.shape, texturecoords.shape, face_vertices.shape, face_texturecoords.shape)

here is the result: (1432877, 3) (0, 0) (2865856, 3) (0, 0) Do you know why?

I met the same problem... Have you solved it?
