I recently started doing some 3D stuff again, and I decided to 3D track a shot, and add a object to the shot (an old C64 joystick modeled in Maya 2011).
I have come to one of the last stages, and that is rendering my stuff. I decided to go for a multiple pass render, with a shadow pass, and then composite in Nuke.
And you can see that only the shadows on the joystick itself is in the pass (I can’t either see any white in the alpha channel). What I really was expecting was that the pass included ALL the shadows, including the shadows cast on the plane behind the joystick! :argh:
I have tried to find a reason behind this wierd problem, and I have sit around all day trying to figure it out. The worst thing is, this is maybe an easy solve!
