Re: Render Channels

[Sam Cuttriss <sam(at)janimation.com>]

ive been enabling them, on the off chance that something relevant is rendered "free"
I have occasionally been able to use the a channel as a matte when comping, but more often than not i just get a laugh out  of them.

that said, im still just wrapping my head round their idiosyncrasies,
perhaps the penny will drop one day and i'll get something useful out of each channel.

my dream would be to render a 1 beauty pass,
and automatically spit out channels for all the passes i painstakingly set up now. (beauty materials might need a few extra hooks to output channels, preferably governed by some kind of override system)

Im not holding my breath though.

I agree but only because of the current implementation. Is there any real reason that those things can't be implemented into a new render channel setup?

So lemme ask ya, do you use them as they are now? And if not... why?

Lemme add to my list something else that would be neat. Lets say they were implemented exactly like passes. Now what if you want to render just a reflection channel but you need to tweak it a little bit. Obviously it wouldn't be wise to re-render the entire thing just for your reflection channel. So... wouldn't it be cool if you could duplicate a render channel into a new pass while maintaining all needed settings?

For me the big workflow killer is the transparency bug - refract rays
only display the output of the main framebuffer regardless of what
channel they are.

I'm not sure, there're a lot of things you need control over that
framebuffers don't solve.  Arealights on/off, finalgather on/off, stuff
like that.  If your load times are killer or you have a lot of
preprocessing (displacement,finalgather,lightmap,shadowmap generation)
then it will probably save you time.
