Indirect specular\glossy with alpha

Post by Rivental1 » Sat Jan 11, 2020 10:17 pm

Hello. Is it possible to get indirect glossy (or any other pass) with alpha? In cycles no. And it is strange for me, after usage v-ray , corona and physical render from cinema 4d where each pass it is image with transperent background. It is very usefull for compositing.

Can't you just use the output of the Alpha AOV in compositing?
Since an alpha channel needs memory, it would increase the memory usage a lot to add an alpha channel to each AOV.
But maybe I misunderstand what you mean.
