Shadow volumes toolkit

How to remove the blackout on the object, but the object to accept a shadow?

 

You can use multiple cameras to selectively shadow the scene.
Render all the static geometry and shadows using the first camera, then the dynamic game objects or objects that you dont want to self-shadowing using the second camera (which doesn't clear the display buffer). This way, only the static geometry will receive shadows and there will be no self-shadowing on dynamic objects.

 

But I need to get shade from other objects (dynamic).
