Vertex Animation output from Houdini

I don’t know if this thread is dead, but I think I’m having a similar issue.

I’m using the Vertex Animation Tool to export a large destruction animation for use in UE4. Unfortunately, on the first frame of the animation, most of the chunks seem disconnected and are just a little bit off. They don’t line up properly, so it breaks the illusion that the large structure is slowly falling to pieces.

Is there a way to make this more accurate? I have turned on full precision UVs in my models, and it looks like vertex color is exporting correctly (I think- at least, every chunk seems to have it’s own color). I’ve also turned off normalizing from zero to one. I thought it might be a limitation caused by the size of my geometry, but I’ve seen this problem on much smaller sims, too. Is there anything else I can try?

Thanks, everybody!
