When I tried in blender (Because these are MeshParts) they displayed correctly and I checked the uvs, however they just glitch in studio.
Additionally, they do display correctly when I Increase the Y axis of the mesh (Yes I know the normals as misalligned but thats cause of the image and normal map being mismatch slightly)
I don’t understand what have you done so the color is messed up but I think it’s texture problem. Is your texture ID blank (so you didn’t put any ID in it?
You can try adding a free model and check it’s properties.
Also, part surfaces are deprecated anyways, so you shouldn’t expect them to work properly anymore.
Specifically, however, the surface appearance that you’ve applied shouldn’t be doing this. Try exporting them as .dds and put them in the local content folder and see if it works properly.
