… I want to try, but I don’t know how to make a portal in Corona… Could you help me ?
make a plane position it into windows/openings and assign CoronaPortalMtl to it. Or use signlesided geometry for glasses and in the material properties->advanced options check the enviro portal option (also for singlesided geometry don’t forget to check Thin(no refraction) option in material->Refraction options)
Thanks a lot lacilaci !
I didn’t try portals yet, because in Corona the lighting is very easy to control, but when I read the comment of Polymax, and when I try to have more quick renders, it’s a thing I have to try…
So I’m going to do it now, so thanks again !
Don’t know, maybe in some very specific scenario you can get such huge improvement from portals, but generally you shouldn’t expect miracles. In some cases portals can even slow down noise converging, so use it at your own risk ;]
