This is an odd little shout, but do any of you know a way to limit anti-aliasing while rendering a model to just the model itself? The problem I'm having is I need to render the model with a floor plane beneath it so it casts a ground shadow, but with anti-aliasing on it blends all the items on the screen, and I need the floor and shadow to remain separate so the model just blends into its own parts.
The image below illustrates the contrast that occurs:

Any ideas on how to approach this? The only thing I could think of was rendering the model without the floor and disabling anti-aliasing against the environment (though I'd need to remember how I did this) and then overlay the end result onto the unanti-aliased render without the floor...but man that feels tedious and there has to be a simpler method.
Any ideas?
