Lightmap Quality Issue

Razorb

Hey guys! i pressume this is related to the type of compression lightmaps undergo... and i feel that i most probably wont beable to really "fix" this.. but maybe there are ways to improve what i have?

I want a pretty white environment with very dark low lighting, but it seems my textures dont have enough gritty information to hide the lightmap artefacts!
Each static mesh has a 512 lightmap baked on production settings in UDK!

Anyway here are the shots, hope you guys have some advice ;(!

This is a screengrab in Lit mode. (Notice along the right side of the static mesh, it looks like some lightmap artefact party!)


Here is the opposite walls in Detailed Lighting view aaaand the lightmap UV's


And finally just a quick unlit view!


Thanks!

Set bAllowLightmapCompression to False in UDK/Engine/Config/BaseLightmass.ini and UDK/UDKGame/Config/UDKLightmass.ini

Performance and load times might increase if your level is large enough, but I find uncompressed 128px or even 64 lightmap looks better than compressed 512 when it comes to bright, diffusely-lit environments.

Thanks Sandro! i will try this when i wake up! its 6:50 am and i need me some shuteye now after attempting to fix this for so long ;D!

Thanks again!

I tested it before and ive gotta say it shows definate improvements even with a 64px lightmap instead of the 512 one as shown above, there are still some compression issues but honestly its ALOOOOT better and workable.

I really really appreciate the help Sandro! !
