# What variables change the number of lightmaps

I need to know what changes the lightmap size.

For example what changes the lightmap from being 2*1024*1024 to 4*1024*1024 - having larger textures or having larger quads (having more models) or having more lights or does it depends on something else?

• Have you messed around with the Lightmap settings? There's a field called Lightmap Size and another one called Lightmap Resolution, if you play and get used to them, you should be able to control the lightmap's size easier – TomTsagk Aug 29 '18 at 14:04
