When importing my mesh, the UV map is being changed. I also have seen this issue with any mesh I am importing from Blender to ROBLOX in the past. In the image you can see that on the side of the mesh (this is also present on the opposite side) that the UV map has been split into two creating a line in the middle that is not meant to be there, the texture should flow across the side smoothly
Thanks for responding. I redid the UVs but unfortunately the error remained. In your image it seems the back side is correct but the front is not so maybe this error is to do with how my Roblox Studio is importing it?
That could be, but for my import into studio it didn’t seem to change the UVs. Can you maybe share the new source file that you are using, so I can check?
However it is worth nothing that it seems some built in materials don’t tile correctly… for example removing the SurfaceAppearance and selecting a built in material:
Does not work, e.g. Wood Planks… seam in the middle on both the front and back:
