Hey guys, just wondering what is the best way to get an alpha layer in RT cuda?
Basically, I have a product sitting on a white stage and I want to get an alpha of just the product. ie so the stage isn't included in the alpha element.
In vray adv I would do this by simply adjusting the vray properties of the stage to have an alpha contribution of -1.0. But it appears this doesn't work in RT...
Any other solution to this (besides turning off GI and using overide material to quickly create the alpha in vray adv)?
Would be nice to be able to save the alpha element with all the other elements in the .exr saved from RT.
