I am creating some paths on a grid at render time using point clouds and need to be able to blur the result so the edges can fade into the underlaying color. I have attached an image that illustrates the paths I am talking about. I don't have enough experience with Point Clouds to solve this my self, and I have not been able to find any examples of point cloud attribute blurring in a shader.
Edit: I found a solution in a SideFX example file that blurs a volume based on a point cloud and transfered this to a shader. Attached is a hip file with the attribute blur shader.
