Hi, I recently face a simple but annoying problem with the last scene I am working on: although I set Irradiance map Min/max rate to -5 / -2, VRay calculates only one prepass … I can’t figure out why: does anyone have an idea ? Thank you

is ‘multipass’ unchecked in the ‘advanced options’ of the irradiance map?

No it is checked: [Irr_map_settings.jpg]

Is distributed rendering turned on in the settings tab?

When DR is active IM is calculated in a single pass.

I didn’t know that, thank you. How does it work ? Let’s say I set Min Max rate to -5 /-2 for the IM and I turn On DR. IM will be calculated in one pass with a rate of -5 ? -2 ? I am curious to learn more about that.

[image] Mining Animation : Koolan Island LOMP IM will be calculated in one pass with a rate of -5 ? -2 ? I am curious to learn more about that. Yes - each bucket will do its own prepasses. Best regards, Vlado

Only one irradiance map pass ... ?!

OK so can you please confirm that calculating a -5/-2 non DR IM will give the same result as calculating a -5/-2 DR IM ?
