changing skylight after irradiance map ic calculated?

[peter008]

can i change the skylight intensity (not color) after i have calculated and saved the irradiance map or do i have to calculate the irradiance map again?

i think you can change the photon energy without calculating the photon distribution again.

i often have the problem, that after rendering a scene i want the skylight a bit brighter. i don´t know if it is possible without doing the irradiance map again.

with color mapping you can, or, try to play with the multipliers. I think that should work too.

and increasing the skylight value will not?
