I’ve imported a simple FBX model that doesn’t have the UV1 Channel that I got from an Asset Pack.
It’s a simple Floor Tile, and when I click the Auto-Unwrap button, the bar sits still.
I’ve found that this happened in the past:
But that’s not clear if it was a bug or a temporary Glitch
I’ve set up a public project with only the asset so this can be reproduced.
