Re: Render Channels

["Axel Akesson" <axel.akesson(at)gmail.com>]

Rendering lights or "light categories" (key, fill, back etc.) separately is a HUGE timesaver. 

For me the goal with render channels/AOVs (or whatever your app calls them) is to recreate the beautypass exactly and to be able to tweak as much as possible. 
Rendering dif and spec per light category (in float of course) enables you to grade/change intensity e.g. only the fill light without having to re-render. It also enables crude relighting systems (i.e. change intensity/color with a tool in Shake and then export the values back into your 3d app).

I don't know if this is possible with framebuffers in XSI yet though.

For me it's strange that film houses have been using these tools for years (AOVs in RMan are great) but commercial houses are still a lot about "the beauty pass"... and commercials have much much tighter deadlines and fuzzy clients. :-)

Cheers,
Axel

I can think of many situations where the framebuffer wouldn't be of much use to you. For example, separate passes for lights wouldn't gain anything because lights are never rendered separately, in fact probably wouldn't be possible.

 

I'm not a great fan of removing functionality. Even without the above, different strokes and all that.
