I am a newbie at compositing and I have been encountering slow render times on 3ds max.
I heard that compositing can speed up work flow
But what am I suppose to start with?
I am currently using brazil or finalrender.
But I maybe depending on finalrender for good
Hi! You may want to check out your lighting setup or run a render diagnostic (or whatever the equivalent is for 3ds max) and see if that’s causing the slow render times…
as for where to start I’m assuming you mean in terms of techniques for outputing from 3d for compositing…
Setting up layers will be dependant on the complexity of your scene and camera moves. You might want to render out layers like shadow,beauty (or specular and diffuse for added control), reflection,occlusion and depth. Or if you have a fairly simple scene with a static camera and an animated object in the foreground, you might to render off the background as a single frame and do seperate passes for the foreground object and shadow. As for setting up shadow passes, with maya you can use a special material called use background which does the trick nicely- i’m sure there must be an equivalent for 3ds…?
If you’ve got an object interacting with a volume light and soft shadows etc, you may find its not worth setting up layers becuase the render times won’t be reduced by very much.
In terms of how many layers to render basically the more layers you have the more control you have when you start compositing but also the more disk space it takes up, so don’t go overboard! Decide what you need the most control over and set up your renders accordingly…
One final tip: don’t render the alpha unless you need it, becuase otherwise you’re using up extra disk space which isn’t needed. Only render alphas for objects which need to be layered on top of things-hope this helps and isn’t too confusing!
