[Max] Tutorials & Guides / Simple PBR Material Index
« on: 2019-07-23, 00:58:21 »
Hi Coroneers!
I am posting a simple index with reflection glossiness and IOR values for PBR material workflow. This is meant to be a visual reference on the range of values to use on a PBR Corona material.
Hope its helpful!

I'm only referring to caustics and for production purposes

I'm posting one with materials. Also i'm posting 2 screenshots. I made a disk targetted light with directionality to 0.8 and then i put a card with a little slit in front of the prism to narrow down the light even further. I'm sending the scene file also

I tried the same scenes without region rendering, with Max sample intensity: 0.1 and Max Photons: 50000. Indeed The render goes faster with usable results from pass 20. Max sample intensity tends to drop brightness for caustics so i suggest using the value of 1.
So the best workflow for know is to render any scene without caustics using the regular settings and then doing a pass considering the above just for the caustics using the caustics render element

[Max] Bug Reporting / Caustics take too long to clear

Hi corona team! Excited with v4!
I did a test with caustics and dispersion and i notice there is a limit on how much caustics are clearing up in terms of noise. I am posting a prism scene where i did a region render on the marked area and the noise dropped to 3% after aprox. 2000 passes! (see attached img) Is this normal? I did the same render without dispersion and the result for the same region was 3% noise after aprox. 760 passes! Still a long time i think for such a small region. (see attached img) Is there a way to increase photons emitted by the light source to have more samples to work with?
I also did a simpler caustics test with a scene with a glass and i noticed the same issue. It doesn't clear in a normal usable rate. 1.5% noise after aprox. 190 passes for the small region area and still not clear! (see attached img) Is there something we can tweak to make it more efficient?
Also i have a suggestion:
Can we have a switch that separates reflective from refractive caustics in order to gain some render time?
Thanks!
