Hello

I have a voronoi fracture of some pieces of a box, super simple set up. Now I would like to “explode” the pieces like the explodedview sop does but only in the z direction. The explodedview sop only explodes from the center axis out in all directions.

Anyone have a simple way of doing this?

Sure, what you can do is follow up the explodedview with an attributepointwrangle and copy the original X,Y coordinates over top the exploded view XY. Then only Z axis will be affected.

pack your geo, try this in a point wrangle:

vector bb = relpointbbox(0,@P);
bb = fit(bb,0,1,-1,1);
@P.z += bb.z*ch('explode');
