Very large lightmapping after bake

Unity Engine

hi, i have a problem with baking light into my app, i have a scene with terrain and basically a map of a town, when i bake the light, the outcome of the baking is around 2.5GB of lightmap data (I marked trees, terrain, mountains, and buildings as static).
My lightmapping settings are :
Direct Samples = 16
Indirect Samples = 32
Lightmapping Resolution = 40
Parameters = Default-Medium

anyone can point me to something i’m doing wrong?

Hey,

Lightmap Resolution set to 40 is very high! You can try something as low as 8, and increase your direct/indirect samples as needed to balance out if there is a drop in quality. Let us know if this works!
