Shader related improvements

[datalost]

Hi! Here I leave my first test.
The same configuraction of the material takes a bit more to render in beta 6 compared with Vray5
And also I've noticed some shiny spots with the new Vray Mtl but perhaps that's because of the energy loss compensation feature.
I would have also attached the file, but it' a bit bigger than the accepted file size.
Please if you want the file, let me know how it would be better to send it.
Best regards

Yes, the map is not working in this build. We'll release a new one soon.

Great, thank you for the info. Looking forward!

Thank you Lele. that I will do.

How does the thickness function translate to a 255 range?
The ThinFilm Shader from Siger Studios used a min-max thickness when used with maps, so you basicly blended between those two thickness values.

New builds where the Thickness map should work - https://nightlies.chaos.com/main#/vr.../beta/20220610

The map should feed values that make sense for the nm range - f.e. a noise tex with a RGB multiplier of 500

Oh. Maybe it would make more sense if we could enter min and max values and just use standard gray image/map as a gradient between those values.
This doesn't look very user-friendly

I agree with Jiri a min & max value would certainly make things more user friendly.

My first Thin Film test.
It is cool, but its really hard to make things look how I want it without more settings.

Had a quick go with Thin Film after map support has been added in the newest version.

Bubble on the left has a simple Turbulence noise going from almost black to almost white, then to an output node with an output of 1200 (anything from about 200 to 2400 amount gives different cool results) to boost the output up to levels that would be more fitting for Thickness in nm

Bubble on the right is without the use of maps to determine thickness..

I think doing it in a way like this makes it rather user friendly, compared to giving Color 1 & 2 an output node each of like 300 and 800 for example, this way around, you can still have the noise on the diffuse of a default material, and check how it would look in black & white, if that makes sense..

But for precise control of colors min and max values will be much better I think. You can deside what color will be start, what color will be ending and how much colors will be in the spectrum. It is more artistic control but it would be nice. Same for saturation and hue shift.

Totally agree.
Here is a screenshot of the Siger Studio Version.
No need for additional nodes.

You can check the new UI in the latest beta builds. No need to set extreme values for the thickness map, it's now properly mapped to the min/max values.

Amazing!
Thanks

Looks great, much more user friendly, thank you.
For thickness map, I assume black is min value and white is max value, right?
