UDK - mesh lightmap problem (yes another lightmap thread :( )

S@murai · Nov 2014

Hello!

I thought I knew how to make good UV's for lightmapping. I was terribly wrong.
I've created this simple celling lamp model. It baked quite well. Lightmap on the other hand look awful.
UV isands have 4px space between them. All islands are pixel snaped. UV's created with Blender.
Please help me!

Your uvs looks fine to me. What resolution you used? Have you tried baking the lightmap at higher res? Because to me it looks like the issue is coming from the really low lightmap resolution.There is no enough resolution to display the lighting/shadows properly.

Here I used resolution of 256 (64 before).

Try to play with the staticlighting level scale under the world properties/lightmass. Try higher numbers there.

So i did some testing. It kinda helped!

staticlighting level scale in order:
0.1 -> 0.5 -> 15
