Premul alpha

[rws]

Hi there!

Is there any way we can;

1- Have pre-multiplied alpha on .png output (ie black background without changing background settings)
----at the same time as----
2- other render layer with background only (showing the sky texture and such).


Current workflow for me is to change the background influence to 0 on the world texture (to get nice alpha blending), and make another separate render to recover the background texture/sky for later composing behind.

Thanks

I wish I knew another workflow too...
But I do it like that too...
