Hi.
I´m making some tests with caustics, and only spotlights and direct lights appear to cast caustics. Area lights cast caustics with a lot of noise (horrible).
And photometric ligths no caustics at all.
Am I missing something?
Thanks!
direct lights are generally the best to use, cause it concentrates the caustics subdivs, where as a Vray light casts light everywhere so you need a much higher caustics subdivs multiplyer to get comparible results.
As for photometric im not sure why they dont work. I will see if i can get them to work.
I generally light a scene as needed then use direct lights for the caustics and make them only affect the caustics (i.e. turn of diffuse and specular for the light)
yes use the direct light!
Ok thanks! I´ll do that
