BlendTuts takes a great look at creating a simple VFX shot in Blender showing tracking and integrating 3D objects into a scene of live action footage.
In this video you’ll learn how to set up render layers, create some tricky materials and finally, how to composite all the mess to end up with a great integration of 3D objects over your footage
Oliver Villar Diz demonstrates how to set the Blender scene up to render separate layers, and creates Conditional materials which will strategically effect the parts of the scene and then provides some tips for compositing the material together for the final result.
