Reflections in Prepass

[szkuls]

Hi,

Im just curious if reflections need to be turned on during irradiance map calculation? Same goes with my dreamscape sky? I am trying to speed up my render and am curious if turning these off would mess up my final render?

yeah you kind of do. otherwise, object that appear in reflections wont get irradiance map samples, and it looks like junk. Made that mistake once on a project where i had a camera in a bathroom looking at a mirror that reflected the bedroom beyond. Rendered out the irradiance map with reflections turned off, and when i rendered final, it didn't look too good in the reflection.
