Hi Guys,
I’m now fighting with this problem still and have done some research. I can’t set index 1 or 2 although I can clearly see all of my 3 UVset in the mesh editor. This is happening on a tree model with 4 Lods and 3 UVset. When I imported simple plane with a material and 3 UVsets I was able to set any index.
Then I had a look into Epic’s Kite demo pack and viola, there’s many buggy assets:
- model SM_Boulder05a has two UVsets, but you can set only index 0
- model HillTree_02 or River_Birch_Hero has 8 UVsets, but you can set only index 0 and 1
Also in Epic’s BlueprintOffice level there’s:
- model SM_Cog_Underground_PipeCap_Top has 5 UVsets, but you can again set only index 0 and 1
… and I could go on and on…
Is there a rule that UE can use only index 0 or 1 for light map coordinate for assets which have more than two UVsets? BTW. it’s happening in 4.12 and 4.11, I haven’t test older ones.
Cheers,
Miro
