  • VrfR4 new gamma options

    I work with the often discussed 2.2 gamma correction settings... the textures had to be corrected with an inverse gamma-curve of 0.4545 individually to get the "right" results.

    now: what about these new gamma features in the "options"-"global switches" rollout? I think "correct LDR textures" is clear, you do not need to individually correct your imported textures anymore, this is cool ;D
    but the "correct RGB" is not clear to me :... it says in the popup "globally applies gamma correction to all RGB colors", is this this color chooser thing (in VrfR3 you had to import little colored textures and apply the inverse gamma curve to it to get your desired RGB values because the color chooser itself was not gamma corrected) ???
    thanx again, ciao,

    The problem was, that the color chooser is gamma 2.2 corrected and the colors must be corrected for Vray internal gamma 1 space.
    So, correct both should work, if not a current bug would cause, that colors are shown to dark -> see bug section.

      ok, thanks micha

      I encountered the "darker" problem especially with glass... so I turned it off ;D

      sometimes it's not easy to keep track of all the tiny buggies

      so long,
