oh... never mind

It depends on the reflectivity of the mirror, just do some tests with higher/lower path depths. the mirror seems not to meet the mirror criteria or I am doing something wrong https://physics.stackexchange.com/questions/305329/are-infinite-reflections-between-two-mirrors-really-infinite Mirror https...

Little else, what the title says What would be the number of rebounds for this in general? https://i.ibb.co/cFJ1mWm/KhQu6.jpg https://i.ibb.co/DCCgMdb/main-qimg-7d84fd6cea1b89c60b4c6455f651381f.png https://i.ibb.co/McKCmch/main-qimg-5847da3d896284792785c1af57903675.jpg https://i.ibb.co/9VVFRRr/TwpBO...

Is this normal at the cost of having less noise?

no clamp



clamp (Set Suggested Value: 7.85)

And with set suggested value is it unfeasible for animation?

Does it work in all render cases?

Barely 5000 samples :? It just dawned on me that the problem with the incoming light could be easily solved by putting a glass pane in front of the emitting plane, outside of the screen. Then it will be a caustic beam like the rest and rendered quickly with light tracing :idea: It is true! Very goo...

Barely 5000 samples

I didn't save that one, but was able to recreate it for v2.3beta on Blender 2.81a. The "incoming beam" directly from the IES light is not rendered by light tracing (because no caustic before going through the first sphere) and therefore extremely slow to converge. I did never finish this ...

Looks good!!! Took u how long render? Test report: This test was done with an Intel I5 and a GTX 1050 Ti with 32 GB of RAM. First example: Path OpenCL with Sobol and clamping of 10.9. Only Path Tracing without any option activated. Time: 28 minutes 2000 Samples + Node denoise. https://i.ibb.co/3WVh...
