Is it possible to create material in blender that can catch/stop shadows without generating itself a shadow? So far i have used material called holdout, but this material is still generating weird shading effects.enter image description here

As you can see this material can catch well shadows but it itself leavs an ugly shadow. So how can I create a material witch can catch shadow (as this material did) and not cast itself a shadow. If some of you can give me answer I would be very thankful :)

Maybe you want to use the Input > Light Path node like so:

shadow light path test

If the cycles ray is a shadow ray, use the transparent BSDF, otherwise use the Diffuse node (or whatever material nodes you want).

The grey cube casts a shadow on the plane and the blue cube, but the blue cube casts no shadow.
