Apply "Inside" material in a Boolean Shatter - fracture effect Aug. 17, 2017, 9:38 p.m.

Hi
When using Voronoi fracture applying materials ti the inside surfaces is simple. You just enable the creation of “inside” and Outside" groups on the Voronoi Fracture SOP.
But when using a Boolean SOP for a Shatter operation how would you accomplish the same thing?

Enable "Overwrite Attributes" on specific frame of simulation...possible? Aug. 17, 2017, 9:14 p.m.

Hi

In my DOP network for a RigidBody test I need to enable “Overwrite Attributes” but ONLY at a specific frame in the simulation.

Is this possible?

centroid instead of $CEX ? Aug. 13, 2017, 8:28 p.m.

So apparently you cannot use $CEX, $CEY, CEZ anymore?

I get a
syntax error, invalid syntax
!

But how would you use centroid() on the Pivot parameters of a Transform SOP inside a For Each block?

If I try

centroid(opinputpath("."),0)
I also get an error,

Unable to Evaluate expression. Name ‘centroid’ is not defined
