Thanks - just to clarify, is this on the KhronosGroup dev branch (which equals the prefrontal cortex repo dev branch)?

No,i'm using prefrontalcortex project, 1.6.1 pre and 1.10.0 pre.

Thanks! I can reproduce, but unfortunately it looks like this is a Unity bug with their Unwrapping.GenerateSecondaryUVSet method incorrectly splitting up vertices. I'll investigate a bit more what the issue might be, and potentially report a bug to Unity.

What looks wrong to me in the model are some flipped faces: image image

Maybe you can try resolving those and see if that helps?

Same with the other model, some faces look wrongly flipped: image

Thanks! I'll try it.

Closing since this is unfortunately a Unity bug, can't do much about it...
