I was wondering if it were possible to find a equivalence between parameters of reihard colormapping of indigo and vray...

res=color*multiplier

post-scale ?

-multiplier
-burn
-gamma

prescale ~ gamma
postscale ~ multiplier
burn = burn

I believe that is not correto, since the gamma in Indigo other option

No, this Global Gamma you are mentionning is applied to RGB colors and textures only.

Talking only about reinhard tonemapping, gamma must correspond to prescale as Kram and I told you

if you just look at how prescale changes the scene, it roughly works like gamma. That was mentioed in several threads and by several persons before... though, it might be hard to find^^

As CTZn said, the "Gamma" setting in Indigo works on textures, not the tonemapping.
