This is similar to a question I asked before. I have some simple text that casts shadows onto a plane. I would really like for blender not to render the plane, but make it transparent so I can use the transparent PNG on my website. (By “transparent”, I don’t mean Raytracing transparency, I mean PNG transparency)
I know how to make the World transparent, but that doesn’t help since I really want the shadows, which means I need a plane.
