What is caution

in world settings, hold on compress lightmaps with mouse and it says use caution when disable this. so what is caution?

in other word it says be cautious because it will increase used memory by 4x :)))))

Hi Shkuk,

The caution is that your lightmaps will be uncompressed when you uncheck the box and that the lightmaps will increase used memory and disk size by 4x.

is uncompressed lightmap size same as texture size?
