Originally posted by Nem thats actually a pretty good idea for simple things Yeap .. for example Jeremy Birns (3drender.com) makes a heavy enfasis on rendering by layers, this way you could actually grab a bunch of layers (say the background ones for example) and batch process them all to a desired effect (You know how photoshop handles effects on 2d images, so instead of letting the renderer actually calculate everything you can manually tweak the results). It has great possibilities (However If it´s an animation better go with after effects which can already comp those images without all the batch-editing-jargon ... ) (or Combustion for all that matters) Great huh?
