Im working on a scene that is quite easy yet client decided do close the curtains at a suny day.
My main light source is the translucent courtain it self, yet It creates awful amount of noise and firlies that just never go off.
My quess is that translucency is not the proper way to aproach courtains like this, yet I noticed something that was quite wierd for me.
Look at the “Render_1”
Mirror object reflects awful a lot of caustics, yet when courtains are taken away it does not produce them at all.
Im curious about this phenomena.
My Light setting is quite simple Corona sky + Large Sun with low power. (Theres a portal in fron of the window).
Note that this are photoshoped images, I managed to get rid of most of the FF, but Im just trying to undstand what im doing wrong.
I’d suggest adding CESSENTIAL_direct and CESSENTIAL_indirect elements so that you can determine if the noise comes from GI or direct light. But this is just my guess.
THANKS
