Default Rendering shadows, for compositing

Does anyone know how to render out a shadow, like from the sun, to my spaceship, and the shadow will appear on the Live Action ground that was filmed already. Does anyone understand?

Yep

This is what the USE BACKGROUND shader is for.

Check out the Docs for usage.

Basicly, in Maya, you create a piece of geometry to "catch" the shadow from your light so it appears to be falling on an area of your bg plate footage.

That piece of geometry is not rendered, but the shadow IS

make sure you go into the shader properties of the use background and turn off its reflectivity if you are just using it for the ground.. I have made the mistake of not noticing that, and it can really screw up the ground.

Not sure about the email notification, I never use it, I always have SM open in ma browsa, so I can just keep hitting refresh in the "new posts search page", and if the last person who replied to a post changes, then I check it out

But on your movie, cool! I'll check your thread occasionally to see when you have a sample of the cg shadow footage available
