I cant Upload Trousers and Hairs. I have followed the Documentation.
Please Help
Hey! The errors in the first image indicate that the Wolf3D_Outfit_Bottom mesh has 2 vertex color attributes which are not supported. Remove them and the mesh should upload.
I agree that the first errors in the second image are not helpful. But it seems there is no mesh in the file which would explain the errors about the bounding box as well.
