Suggestion - Layering

[gah5118]

check out the lighting mixer in fryrender or in maxwell, this is a great post-render feature

also being able to have alphas of each object or matting would be great for composites

render passes basically.

This one is off the topic but the ability to adjust your max samples with out it resetting a render. in other words if you increase it it wont start from the beginning but from where it left off, or if you lower it so it stops sooner, it will just stop at the desired sample.

Thanks.
