realtime feedback for tonemapping,exposure, gamma correction, camera vignetting

[pengo]

I'd like if could have in vray realtime feedback for exposure, gamma correction, camera vignetting, camera white balance even into the view image file command (watching the vrimg)

thanks for vray yet as it is of course

There is V-Ray RT for that

The problem in the regular V-Ray is that these settings affect the calculations for GI, glossy reflections etc. For example, if you take an image that was rendered as dark, and try to brighten it up you will likely see noise and splotches. In reverse, if you render an image as too bright, it will take longer to calculate and you will be wasting time.

Small adjustments are possible, of course, but they are perhaps better left for an image processing application like PhotoShop.

Best regards,

Vlado thanks for the reply but i don't think is proper the same thing what u told!
Interactive during rendering is very different from realtime with vray RT solution I use it (RT) and is not proper the same concept I expressed and I'm sure u understood what I intended.
