How do you delete a second UV channel on an older model?

Hi

How do you delete a second UV channel on an older model? I’m using Lumen and have migrated an older asset that still has a second UV channel from the days when we baked lighting. When I try to delete the second UV channel, Unreal displays this warning below which doesn’t really explain how to remove it. I’ve already unticked Generate Lightmap UVs, but the second UV channel is still there. Is the only solution to export the mesh, remove the UV channel in my 3D package (Blender), and then re-import it? That seems like a pretty backwards workflow for something that feels like it should be simple.

Make sure the UV Editor plugin is enabled.

Right click your mesh in the level, select UV Editor under Actor Options. Look for the Channels tool, from there you should be able to select Action “Delete”, select the channel to delete and Apply to finalize.

Ah, thank you, that works a treat!

I will have a good look at these tools
