Dispersion test but strong colors

[nuno1980]

Hello.

My scene:
- circular tape mirrored
- ball light in inside of semi-ball mirrored
- prism w/ refractive index 1.5 and dispersion 1.0
- torus knot (blue clear) w/ index 1.6 and dispersion 0.018

screenshot:


I used PMC kernel with 32 max depth, 10k-reject, 45k-sample, caustics blur 0.00 and parallelism 2.

Strong colors are bad!? Why? Because the maxdepth 32 isn't sufficient? Will the newer version improve from 32 to 1024? Or has OR plugin for "3DS Max" infinite max depth?

[nuno1980]

Please should response! Due to my EASY question.

I'm not sure what you're trying tidy, or what you're asking

[nuno1980]

Will I need more samples? Or am I waiting new version of OR w/ max depth increased?

What am I looking at?

[gordonrobb]

Could you explain again which part of the image you are concerned with, perhaps circle it or something? I don't know what it is you are asking - sorry.

[nuno1980]

Better understand to see new image. But sorry for bad english.

OK, so you are talking about the tray caustics, on the right hand side of the image?

If you are, then you need to let it render for longer. Personally, I would reduce the maximum depth. Think of the depth as how many surfaces you want the light to go through or reflect off. With less, it may be cleaner and render faster. However, the number of samples is what will take the noise away (eventually). If you are using PMC, try Path Tracing. Also, try to add a little Caustic Blur perhaps.

All of this is assuming you want the caustics

btw, I have no idea what a 'circular tape mirror' is

Tried PT but good caustics appeared are too much later.

I have changed DL imp to 0.2 and parallelism from 2 to 1 in PMC settings. I want keep 32 max depth because less max depth is less realistic.
Sounds look much better. I will post tomorrow new image with 50k- or 100k-sample.

hi,
my suggestion is to leave the coustic blur at the default value (should be 0.010) or something near, otherwise the coustics will never clean up.
Octane 1.52 can go till 2048 max depth and all the plugin that use the this sdk can do the same.
