problem with fracture voronio and Arnold subdivision tag

[Anonymous]

I'm having a problem here, I used a fracture Voronoi, then I added subdivided the mesh using Arnold tag, im tried liner and catclark , the surface should not look like this, it should look 100% flat, here are the images before and after the Arnold subdivition tag , so please if anyone can help with this

This has come up before (type voronoi in the search above). For example here:

The best thing for Voronoi is a dense mesh rather than using render-time subdivisions. As the subdivisions will make it smooth the edges, unless you have set up creases (https://help.maxon.net/us/index.html#OSDS-ID_OBJECTPROPERTIES)

but this will make the viewport very laggy!

yes but no answer there !

[ashley.handscomb.retallack]

If you add creases it shouldn't be as laggy as the number of vertices won't change, are you after adding displacements to the inner faces?

As for viewport lag with dense meshes, this is where you may have to start having proxy meshes and replacing at render time with procedurals.

yes im After displacments for inner faces , how to add creases ?

[ashley.handscomb.retallack]

Here's a video on adding creases, you need to convert to subdivision surface https://vimeo.com/125698748

It may not help in your instance however
