nodes for complex lookdev

[alessandro_dele]

Hi everyone, i'm working to a port from arnold to vray for a library of characters that shares same uv and topology. Those characters shares a library of udim textures and masks we use to control a lot about the look, from sweat to skin feature to dirt. So i would ask about some features i didn't find in the last release

- a mask input in the vraycolorcorrection node (a lot of features in the characters are controlled by shared masks)
- a range node (also with a clamp feature), like the maya set range node but more optimized for 16/32bit files like displacement masks.
- single basic nodes like subtract/multiply/add/divide (about this i solved with vraylayertex, but maybe single nodes would optimize and lightweight tha calculation)

thank you!

You could do this with a VRayLayeredTex as well. Otherwise, you could add your idea to the Portal.

- a range node (also with a clamp feature), like the maya set range node but more optimized for 16/32bit files like displacement masks.

What exactly do you mean by "optimized for 16/32 bit files"? More positions after the decimal point?

- single basic nodes like subtract/multiply/add/divide (about this i solved with vraylayertex, but maybe single nodes would optimize and lightweight tha calculation)

Don't the Maya ones work for you?

- Yes i added and idea for the mask input in the color correction node, of course could be done with VRayLayeredTex but something like desaturate only some areas would be more easy with a mask on the cc node i think.

- In this case i used the setRange from maya but working with 32bit exr displacement i noticed that work different from expected (a migrating from Arnold using the aiSetRange), so i think that node is a float 16

- Unfortunately the maya nodes are more "rigging oriented" and have only one input float, so if i have to do add or multiply an rgb i'll have to add 3 nodes.

Anyway those are just suggestions i think could help to slim down complex shaders, nothing is missing

Have you checked the File node's "Allow negative colors" V-Ray attribute?
