Can the subdivide and displace node not change the physx shape hulls?

[xtremist999]

Hi there,

I'm doing a basic voronoi fracture & physx smash effect, and I want to add subdivide and displace to give the frags some subtle rough edges, but I don't want to send the frags into a new event to do apply these nodes. However, I'm finding that it changes the shape of the original physx collision hulls, which is what I don't want.

Is it possible for me to subdivide and displace the voronoi frags in the same event as the physx nodes, but work as a post process effect so that it doesn't change the shape of the physx convex hulls?

Thanks

Unfortunately, no. Currently PhysX hulls will update any time a change to a shape mesh is made.

If you want to apply displace/etc without affecting PhysX, do it in a reference flow after simulating the un-displaced particles in another flow.
