[Max] General Discussion / ComplexFresnel

« on: 2020-02-17, 12:02:41 »

So I've been delving more in-depth about the ComplexFresnel usage, as seen most Metals in CMPP2 use it.
R wavelength - 0.650 µm
G wavelength - 0.510 µm
B wavelength - 0.475 µm
Platinum wavelength - 0.002 - 0.121

How do you calculate n and k values for RGB wavelengths when they exceed Platinum's wavelength range ?

[Max] Bug Reporting / CoronaTonemapControl doesnt work or am I missing something ?

« on: 2020-01-15, 17:58:30 »

So i tried using CoronaTonemapControl to turn off tonemapping of a background in VFB but it still is affected by it.

I tried restarting the render after making changes to Tonemap precedural map but nothing seems to work...

Am i missing something ? or maybe it doesnt work with direct visibility override ?

[Max] Feature Requests / Re: The most wanted feature?

Want CoronaLightMtl working with LightMix above anything else... ;)
The fact that all LightMtl's are auto-stuffed together into Rest(Unassigned) is annoying
And resolving this could save up a lot of work-around time :)

[Max] Bug Reporting / Re: Caustics solver causes eye-bleeding fireflies

So, after I've done some searching, i found that my HDR is very concentrated on just a few pixels in the center of the sun. This caused some of those firefies to vanish once i adjusted it in Photoshop.
And since using environment to cast caustics already is double edged sword, note to others: do not use HDR with a very concentrated luminosity/radiance levels. In fact, dont use HDR for caustics at all. :)

At any rate this mildly helps, Anyway maybe there is a way to have caustics overriden to refractions only? I don't really need reflective caustics, i only want the caustics that are visible in pool through water

apart from different people, extra bushes in the front and added curtains, everything is the same

It renders for around 1 hour, till noise drops to 5%, final resolution 4000x2250 (16.9)

Unfortunately, fireflies appear even when rendering full scene at once.
I've just done some testing enabling "caustics solver" but not checking "Caustics" itself in the material tab, the fireflies are still present

[Max] Bug Reporting / Caustics solver causes eye-bleeding fireflies

« on: 2019-12-04, 13:52:26 »

So I've done a quick render with a poll water material having caustics enabled. Everything went good.
Then after client asked to replace people with a more summer attire, i rendered scene and noticed that caustics cause disgusting firefly stains
What is happening? There are no other light sources in scene. I've tried resetting corona settings, converted scene, nothing seems to work.
Any idea what is the problem?
