Redshift Caustics Tutorial

[@chr1st0pher]

what about the intensity multiplier/number of photons to emit? thanks a lot awesome tut, was missing the "enable caustics" in the mesh when I tried this previously. Also didn't the documentation say that photon mapping always runs just for caustics even if you don't have it enabled as either GI mode? I seem to still be getting caustics with irradience cache as primary and brute force as secondary so maybe there's no need to use photon map -- that seemed to be the sense I was getting from that documentation.

Ah yes, I knew I forgot something. Intensity (under your light's settings>Caustics) essentially will make your caustics brighter, number of photons will shoot more rays cleaning up any irregular 'spotting' that might occur in the render where there should be caustic reflection/refraction. You're right about Photon Mapping too, I misread the docs thought it had to be enabled always, that said I think there is a render time benefit having it as one of the GI's. I'll pin this comment so others can see it, thanks for that!

[@chr1st0pher]

definitely a render time benefit in the tests i was just doing. thanks a lot that's super helpful :)

[@IXFALLS]

Yes! Another video :D

[@SmallRobotStudio]

At least 2 a week!

[@ahahlex]

thanks for the explanation

[@SmallRobotStudio]

No worries! :)

[@raskal8578]

can you explain texturing fur and hair in xgen?

[@gowthamanm3834]

could u do matte id in redshift and renderman pleeeeeease that would be reaallllllly helpful to my archviz projects pllllelelesa

[@mitigatekeeps1371]

You can have both caustic refraction and reflection.

[@SmallRobotStudio]

+Mitigate Keeps true I should update the video description

[@postamartin]

more Renderman 21, please

[@SmallRobotStudio]

Splitting my time between Redshift and Renderman tutorials at the moment so you'll see a bit of both and more.
