I just saw a similar question and it mentioned adding UVs to the model. I will try that and report back to this.
There are a couple of possible causes to this issue.
- The object has no UVs (UVs tell the object what part of a 2D image goes onto it's 3D form)
- The object has bad UVs (if the UVs are overlapping, stretched too badly, or malformed in some way it can cause errors)
- The object has bad geometry (overlapping faces, inverted normals, and broken edges can cause this)
We're working on catching these types of errors and fixing them for the future.
I had converted an .stl file into an .obj and .obj.mtl file (the conversion produced these two files. I imported the .obj file, but Dimension didn't seem to use the .obj.mtl file where I think the UV data may be held.
So, like the original question, I got the error when trying to place a graphic on the object.
Any advice or updates on addressing this issue?
