Using Vray 2_1 stable. Noticed there´s a “Linear workflow” checkbox under “Extra attributes” on the SSS2 shader(on by default). What´s it for? Does this mean you don´t have to gamma correct the diffuse, subsurface, scatter colors etc. ?

It determines whether the fastsss2 material follows the global “linear workflow” option in the color mapping settings or if it should never apply any correction to the colors. In general though, I don’t like the global “linear workflow” option I do not recommend using it - it’s very inconsistent in …

So do you recommend unchecking the “LWF” on the SSS material, if I use the default linear workflow settings under colormapping (not the “LWF” checkbox), but gamma 2.2, don´t affect colors etc. ? Or does it only have an effect if if you use the global linear workflow button?

[image] V-Ray and Maya 2013 it applies the correction on the entire result of a texture shading network, whereas the correct approach is to only apply it on the input data - File nodes or colors. Interesting, is it possible to expand on this please Vlado? Does this mean it affect the actual sh…

Hmm, I see in the latest nightly there is this message in the output: Warning: The linear workflow is deprecated and will be removed." :shock: I guess that answers my question. :slight_smile:

Hehe ok then :slight_smile: The results from that option are generally too unpredictable (like it affects some things, but not others, it affects the result of a texture graph rather than the input values and so on). Best regards, Vlado

No problem - thanks for explaining it. BTW if you guys really are going to remove Linear Workflow tickbox, is it possible to please add in a new VRayColor node like 3DS Max that can have gamma controls on it similar to how you’ve implemented gamma controls for file textures? That would be very hand…

Thanks for the suggestion, but the viewport material just goes black then because it’s ported from Max.

[image] Noise threshold per object or material? Thanks for the suggestion, but the viewport material just goes black then because it’s ported from Max. Yeah, that’s annoying - I’d love for this to be fixed as well.
