Hi, I am new to Houdini world. I have a question about deep shadow and motion blur. For some reason when I apply deep shadow I get a shadow in a front of the object.In the scene there are two point lights one in a front and one behind the object The front one has a depth shadow with transparent turn on .I want to use micropolygon rendering and motion blur.I know that if I use ray-tracing I will get automatic motion blur on a shadows, but it's too slow.Is there any way to get it to work with deep shadow?
What I am missing ?
here it is a test render:

Could you attach your hipfile to this post? Something's fishy..

Shadow bias issue. Increasing shadow bias to 1 lays the shadow in the right place.
Tweak the shadow bias until the shadow lies correctly. Too high a value and the shadow will jump off the feet-ground intersection (just try a value of 5 to see this).
The shadow bias is in Houdini scene units and is optimized for objects that fit in a standard homed viewport: from 0.5 to 10 units in size typically. Your character is around 170 units high so the bias has to be adjusted upward.
Shadow Bias is used to help the renderer figure out what is in self-shadow and what isn't in self-shadow. The bias value is added to the value in the depth map.
Shadow bias is used in both raytraced shadows and zdepth generated shadows. It tends to need more “management” with zdepth shadows.

There's at least one school like the old school!
