Trying to render out UV templates to png images, it's completely broken. My object is a fully welded, manually UV wrapped "room". Attached images should show the problem reasonably well enough.
- Depending on image size, the results change.
- When face materials is on in the UV editor, they are not rendered in the correct place / scale .. etc.
- The edges are not rendered in the correct place.
Perhaps it's just the object I'm testing, but it is properly welded and unwrapped (see images).
