I started noticing shadow errors in the corner of each rect light. Does anyone know how to fix it or, otherwise, how to undo lightmap built?
Note: Also, in addition to this, light looked worse on prewiew after rebuilt.
Already solved the issue by changing light from stationar to movable. But still have a question.
-Can anyone say, does that affect ingame fps if I prebuild lightmap?
-And how to create UV maps for light? is it hard?
