Hi,
I have a still photo which I intend to integrate CG objects into. My issue is that when I make my CG object sit on the floor, there is not contact shadow 1.) applied to the CG object and also 2.) no shadow cast on the floor visible in the CG object's reflections.
This is my setup:
I've reconstructed the room in Maya...
...and applied a material wrapper on all meshes. As base in the wrapper, I'm using a light material. The light material is projecting the photo onto the meshes.
When I render this, I get all my CG objects against black and the shadow is present in the alpha channel (which is great for compositing later on):
However, I notice (in the render against black above) that I don't get contact shadowing (of the floor) in the CG object's reflections. A CG object sitting on the floor should also get shadowed at the bottom of itself by the fact that it is close to the floor.
If I place a plane at the base of the CG object and turn primariy visibility off, I see that this contact shadow I am looking for is appearing. However, I am trying to find a solution in the shader network rather than having to work with double meshes...
Any ideas on what I should do to make that work?
My issue is basically that I can't cast shadows onto a light material, I guess...?
The light material is all at default values. This is what my wrapper materials looks like:
Any help much appreciated!
I'm on one of the most recent nightlies.
