Displacement map visualization gets clipped within the bounds of some geometries

In this image, you can see a displacement map on a plane. The displacement in this case gets clipped within the boundaries of the plane geometry. I have seen more similar clipping artefacts with other geometries as well.

Forgot to mention, engine is NorthStar

Can you attach some way to repro this?

I have attached a trace. Thank you for looking into this.

Technically, I believe the engine is still using the original bounding box of the mesh to perform clipping and culling. The bounding box should be expanded accordingly to the displacement.

The problem has been fixed. Good job!
