render mask issues

[lorenzo_spinola]

Good morning everyone,
I tried to use the render mask for the first time yesterday, hoping to save some time having a 2nd option for a different material, but I had some problem using it, in particular:

-when I start to do the second render, the first one is not refreshed, so I see my second render on top of the first one...the elements in the first renders ar not deleted
- Sometimes, AA looks very bad compared to the whole render.

A video here to show the problem: https://youtu.be/cam24FFNJN0

Is there any easy workaround to this?

Set that rollout to "advanced", then set the shown dropdown to "clear".
The AA is fine, it ought to look allright when comped (see the actual alpha).
