I recently working on a faceless staff and when I try to upload lod0 it says there is 2 materials and only 1 material permitted. I tries everything I can think (Deleting all materials, exporting as fbx, export with "ignore material" option) still nothing. İs it a bug in importer or I did something wrong? Thx for all…
make sure you're using a default program matereial, like a blinn or phong, not any dota textures. Also make sure both LOD0 and LOD1 are using the same one. If you use Material #01 in the editor, use that for both LOD's and you won't have an issue.
