Hello,

I'm new to the Houdini, and I’m trying to make some basic stuff, Torus was broken via voronoifracture and drawn on the flor via rigid body dynamics. If you don't switch on the Redshift mesh deformations blur - everything is fine.
Before Redshift mesh deformations blur:

If switch it on, then artifacts appear at the boarders of the meshes. Sounds like a normal angle smooth artifacts.

I tried to put the facet node and took advantage of the internal switches of cusps angle. But there are no effect. Maybe there is not obvious to me, as a beginner way to fix this? All tips are welcome.
