desaturation of HDRI

[kpavlov]

Usually when I render with linear color correction and use blue sky HDRI all my scene gets that blue color. Its a little less noticable using exponential color corection but its still there.

The solution is to desaturate HDRI map in Photoshop and usually I want some color to bounce from HDRI map so I have to guess how much I have to desaturate it in Photoshop. ( I dont like when its desaturated totally )

It would be a great help if there is slider 1-100% in material settings to desaturate HDRI directly in max so there is no involvement of Photoshop in the process. Hdri doesnt have to change phisically , just Vray can take into account how much we desaturated it.

Is that possible to implement in Vray.

kpavlov have you tried coloc correct plugin for max? works really well on hdri, plus you can adjust colors of hdri, hue etc.

Are you talking of HDRI being reflected, or of HDRI as a source for GI lighting?

For the latter, you might wish to check out the saturation multiplier under the GI panel in the VRay settings...

Better yet... split out the G-Buffer, rebuild the render in comp, and do a color correct in post.

indeed

Composition rulez!! Comp or die!!!

BUT

Color correct is very cool indeed.

Use whatever it takes, actually.

I also prefer the color correction plugin over comping. For me, comping requires a lot of additional work, understanding and software. I usually don't do animations so in these few cases I need to rerender something it's not that a big deal.
