Ok … as i found so far … the shadow only option in blender … receive only shadows but the object him self also cast shadow in another object and adds that to the shadow.
How can we make the " shadow only object " only recieve and not cast shadow !!!
Many thanks
A couple of ways:
Use buffer shadows and disable the objects ‘Cast Buffer Shadows’ option
Put the shadow only plane on a different layer to the lamp and in the lamp / shadow settings enable the ‘This Layer Only’ option.
Can you also post support questions in the appropriate support forums, not Blender Discussion forum
