Good day ... very very slowly ... and is considered to be caustic in animation sometimes it is not justified to use. Tell me do you plan to manufacture fake caustics or optimizing for animation . THANK you ! Now when rendering jewelry I use caustic i-ray visualization frame HD = 25 seconds/// at PMC, it takes 10 to 25 minutes = I understand that this caustic is physically correct but I don't have time to wait for Octane Render will process light. ( 3D max / 2016 // 2.15 v)


as you can see I need to add caustic . and I can't generate it through PMC slowly

Fake? Why do you think Iray is fake?
Iray is a path tracer just like Octane is. It just has optimized algorithm for caustics.

you will never see caustic in the secondary reflection of the metal iray caustic sampler . so I call it fake ... in the new test version of iray caustic soda is also considered to be long if it is considered in physics

Enable architectural sampler too and wait a bit longer. You can't get caustics to reflections by 25 sec.

I waited a long time but I never saw the secondary reflection in the mirror caustics

The Iray renderer does not allow to do this
I think it was because this particular algorithm is so fast because the beam is cut immediately after 1 reflection
( 3D max 2016 standart IRAY )

really looking forward to from the developers of optimization of caustics. thank you all.

can we get the same. I dont care if caustics is visible in reflections. Would be great for animations
Would be nice if other kernels supported caustics like AO
Thank you

I made a similar quick test scene as you had.
Standard Iray that comes with Max 2016.
I DO get caustics in reflections.
