VRAY color gamma correction.

The gamma correction field in vray color doesn’t seem to work correctly.

eg: color value of 122,84,59 is given a specied gamma correction of .456.
This changes the color swatch in color parameter to 51,22,10 (as expected). However the max material sample slot is not effected and still displays the uncorrected color: 122,84,59. Max renders and displays the uncorrected color.

If you select “none” on the gamma correction but stick the vray color map into a color correction map with a advanced RGB gamma of .456. The corrected color is passed through to the shader and renders and displays as expected.

QED- the color correction field in vray color doesn’t seem to be working.

This is how it is designed to work.
The Gamma correction is applied only to the displayed color swatch for the Color parameter, it does not affect the actual RGB values.

Use Color Gamma instead - it will be applied during the rendering but not on the swatch.

That’s okay then :slight_smile:
