shadow compositing
hi there i want to compose an object in real footage, and i want to have a shadow of the object, my method is to render with a floor and to create an object buffer of all objects and to have a multipass of the shadow, illumination, object buffer, and then i compose all in AE.
Is there another way to do this? Without putting the plane?
Cause when i put a compositing tag in the plane, to not be seen by the camera, the object and the shadow desappear.
Can anyone help me?
Thanks a lot
