irradiance & light cache

[bertjow]

Hallo

Could anybody give me advice how much I can increase resolution using irradiance and light cache map. I mean first render will be lets say.. 1000x2000 pix then after render its done I swith to load from file (irradiancemap and lightcache). And here is the guestion becasue light was already calculated can I increase resolution 100% to 2000x4000 pix or only 50% to avoid looseing to much on quality.

It depends on what your original settings were for the irradiance map, but in most cases it will be fine.

It mean that anytime I duble the resolution I have to decrest irradiance map?
