"Zero UV area or surface area on mesh" after QuickEdit.

Recommended Posts


I edit some of my meshes with QuickEdit, and when I try to bake lightmaps, I get this Yellow Warning on some my meshes and console "Zero UV area or surface area on mesh", which I previously edited with QuickEdit. As result, lightmaps does not include this meshes even if they are static ( No lightmaps No shadow maps ).

The strange things is If I edit 10 meshes with QuickEdit, not all of them affected, just some of them, it is like rolling a dice, chance factor. I use latest version of QuickEdit and Unity 5.6.4p1. This could be a kind of bug which broke the mesh structure so lightmaps does not include them anymore.
