Hello Houdini Users,
I've got a simed object that once broken, the faces on the interior of the geo shift as they settle. is there a way to triangulate the geo without it shifting or moving?
I have a hip file and mov file showing what I am referring to.

You can partially fix the problem by putting in a rest geometry in the 2nd input of the divide node. My simed out animation is quite different from yours but I noticed that the geometry changes a lot from frame 44 when the glass hits the ground.

By plugging in the geo from frame44 the divide sop uses that as the rest geometry to do the convexing (it's in the help).

The topology of the input geometry changes again in frame 99, 133 and 188 from 21310 points to 21308 points so the divide will have different results again. (The reason for the popping in the video) So no fix for that even by switching to the new geos.

You could triangulate before dops if sim time is bearable.
