I’m told UE Marketplace requires static meshes have more than 1 UV channel. Relating guidelines that read:
2.3.3.c Static meshes must have no overlapping or wrapping UVs for lightmaps.
So my questions are:
- How can I add another UV channel?
- And why?
They’re very simple meshes created with UE’s modeling tools, so it’s odd they don’t meet requirements. But maybe that’s been updated in the tools. I know at least some were created in 5.0.
