Overlapping Uv's when building light (Lightmap texture resolution)

Development Rendering

Hey guys,

when i bake the light i always get an error when the “Overriden LightMapResolution” is on the default value (64)

When i change it to 1024 then i dont get any problems. Is this a common problem? What’s maybe the resaon?

cheers

Most likely your lightmap UV’s are not very good. If your UV’s don’t have enough space between them then a pixel can bleed between the parts.
