Hi~Everyone
After reading doc, it says you can use Render Channel to separate channel in one pass, like diffuse,specular,reflection....etc.
But in Render Pass is also can only render diffuse or reflection...etc. So , what's difference between Render Pass and Render Channel in function ?? Or someone can says something special using of Render Channel.... :)
Thank you~

With passes... each is rendered seperately, for instance it takes 3 minutes for your occlusion pass, and then 2 more minutes for your reflection pass.

With channels, they render at the same time but create two separate files (or at least images)... running them together may take only 4 minutes instead of the 5 minutes to render them separately.
