I have finished a building, and I'd like to render it in Cycles:
As it is with shadows: I know how to do it. I've done it and it looks great.
As it is without shadows: I know how to do it, I just untag 'Cast Shadow'.
Only with shadows: I don't know how to make the mesh dissapear from the render and render only the shadows. This is where I'm struggling. I tried to find help online but they're all old guides from a different version of Blender. I also found ways to do it with Nodes, but the question is: Where do I set up the node system? In the World, Object or Line Style? And how, because if I set it up on the World it will overwrite the other nodes that I use for texturing.
Thanks for the help!
