Energy Preservation in v ray rendering

[nilariver@gmail.com]

Any body can tell how to manage energy preservation, which causes colour change because of reflection and refraction. Basically how do we get actual slot colour in the rendered image ? (In 3Ds max vray rendering)

i think your question is a bit unclear

I *think* (iv only used it with white) using Lele's linear workflow method with the colour picker will allow you to get exact RGB colours / values with 'perfect' exposure.

 

Download his videos from Chaosgroup and have a go, once you get your head around it its fairly straightforward.

 

Is that what you meant? Do you really need exact rgb values in your rendering anyway? I can see how it might be important for product vis.
