I did this just as an exercise in max. The inner dark tray proved very difficult. I had no clue what would be the best way to do it. Took me almost a week until I found the solution.
Anyhow, I have 3 VRayLights in the scene and, especially on the opened case, it’s quite noisy. Even though all lights’ sampling is set to 32 and I’m rendering using
IR: 50 subdivs - High preset
LC: 1000
It took about 15 minutes on an AMD 4800 dual core. So at this point I’m ok with the noise. I don’t know how to lower it without rendering it for half a day.
Well, the subdivs for the ligths were 32!!! However, I’ve seen the light last night (pun intended
I changed my LC to Brute Force, and I’m getting not only much smoother renderings, where the noise virtually disappeared, but much faster render times as well! Instead of 11+ minutes now I get around 4-5.
Here’s the new rendering with re-configured setup using Brute Force as secondary (IM as primary bounce). The noise are GONE!
Primary: IM - preset: High - HSp/Interp: 50/50
Secondary: Brute Force (default settings)
Caustics On: Default settings
AA: adaptive subdiv - Filter: Catmull-Rom
Instead of 3 VRayLights, I only have 1 now with 32 subdivs
Rendertime about 7.5 minutes
sv: thanks for the comment! here is the screenshot of the setup. very simple.
