Camera Tracking - How to cast shadows from objects in footage to object in scene.

Support Lighting and Rendering
1

Greetings,
I encountered some problems trying to cast shadows to object from footage.
What I tried:
a) Camera tracking of footage, setup default tracking scene in move clip editor.
b) Build geometrie which should cast shadows on character.
c) Switched off in object tab > cycles settings > camera visibility > camera OFF.
But it casts shadows on footage as well .

In the pictures below you will see:

  • The node setup generated by the movie clip editor after tracking.
  • A render where you see the light shadows from the geometrie and the darker shadows that are the real shadows in the footage.
  • The geometrie I build on layer 1.

I hope to receive some suggestions on:

  • How to cast shadows on character but not on footage from the geometrie I build.
  • The left leg is to bright: it receives to much light from environment map,

Regards,
Robert

I think I have to put the poles in layer two and play with the renderlayers there.

update:
Ah that was the trick:
Put the poles geometry in layer two, and in the background layer mask layer two so it won’t have any influence. ( I hope )

I also put a plane on layer two on the floor so the character won’t receive to much light from below. Now the left leg seems to be ok.

There is still a small problem with the shadow on the first pole which shouldn’t be there.
