Lightmapping Artifacts! - Help Needed

Unity Engine
1

Hi guys, any light mapping gurus out there?

I’ve set up a rather large scene to light map with Enlighten, and while the majority of it has light mapped ok, I’m getting a few funny artefacts which should not be there!

The dots in the top left, and the ‘black splodge’ near the middle of the image.

All the hanging grasses and vines I have actually changed the settings to: Cast Shadows OFF and NOT light map static, so I don’t think those objects are the issue?

I’ve attached my light map settings below also. Does anyone have any ideas what might be causing these issues? Thanks guys!

The dots on the top left look like overlapping UVs.

Are you generating lightmap UVs for your meshes?

Thanks for that - I was so convinced it was due to the vines that I never bothered to see if the Generate Lightmap UVs box was checked. Indeed it wasn’t for some reason - now they bake just fine :slight_smile: Cheers AcidArrow.
