Title: sRGB mode
Post by: art-MIXER on 2013-12-18, 12:55:49: hello everyone
Please tell me , how do I make it so that would result in rendering VFB displayed with gamma 2.2 ( by default ) but write OpenEXR file for compositing with gamma 1. In Vray I used in the settings of color mapping ( do not use ... ) and display mode sRGB, to display the result with a gamma of 2.2
So I get the original file with gamma 1 and opening it in AE or Nuke, it displays correctly , and in the case of the Corona he writes a file with gamma 2.2 and it turns into double conversion compositing . How to make a save with gamma 1 and the map in the VFB, mode sRGB mode ?

The concept is simple! Somehow I slipped my mind that there is a mode while maintaining override, thanks man, sent to the right path)))

That's just I work in 2014 Max and do not work in the automatic mode for 32 bit files. Corona autosave writes with a gamma of 2.2

What happens if you use the regular VFB from 3dsmax?

Conservation through standard automatic mode works correctly. Corona autosave does not save with gamma 1 simply uses its own gamma VFB

Works just fine for me.

Well, in general I did so
