Proper way to render using linear workflow?

V-Ray V-Ray for Maya General

I have been pretty confused about linear workflow and the correct method of rendering it. Is there a way to render out exr’s (16 bit) in linear workflow, and not have to manually gamma correct each and every texture? Right now under color mapping, we are putting it at 2.2 gamma, checking on “don’t affect colors”, and checking on “linear workflow”. Then in the Vray viewport we are turning on the sRGB button. Is this correct? I remember vlado saying to not turn on the linear workflow checkbox, but then you need to add a gamma correction to each texture in the scene… We are using 8bit textures by the way…

Also, what should the flame guys who comp it be doing to it when they get it from us?

Thanks

This script automatically adds gamma nodes to all the correct slots in all materials of the scene.

Thanks. So is everything I am doing correct, but I should not be turning on the linear workflow checkbox? (which means I have to run that script to add gamma nodes to everything?)

Sounds like ur doing most of it right. Though no need to check on “linear workflow”.
I’ve been using crGammaCorrect 1.5b mel here for my textures. Also turn on "Convert image to sRGB’. And the compers should be asking for 16bit scanline zip Exr’s (I use multichannel) though usually they
will just take what they get and change it in Nuke.
Ok.. looks like jjGamma tools is a bit more robust,.. though i’m not sure why all my texures switch to some proxy looking low res version of my real texture… I have to switch it back in the unwrap editor.

For the textures you can use the Vray Attribute “Texture input gamma” for color swatches I use the JJJ_gammatools … which helps a lot …
