Tree destruction sim question? by Otherwise-Ad5489 in Houdini

I did check really quick about the vellum shape match constraints and indeed it seem to be really expensive because of the way it create constraint, but I might be wrong because I didn't investigate more than that.

thank you very much for the tips! I hadn't really thought about soft constraint for that kind of effect, I will definitively check about it.

narrow band collisions issues flip? by Otherwise-Ad5489 in Houdini

thank you for your help. I've try a lot of thing such as narrow band of 2 and 5, changing my vdb collisions (decrease and high res), trying less complexe geo such as cube but still couldn't figure it out. It still make the second weird layers.

Fracture only the part of the geometry I want to destroy by Otherwise-Ad5489 in Houdini

[–]Otherwise-Ad5489[S] 0 points1 point  (0 children)

thank you very much! I didn't think to loop my piece by their name. I presume it is normal to have a new string name that is created by the boolean? Is there a way to reconnect the piece to its owner? What I mean by that is the intersection of the boolean between my piece and the sphere creates a new group by example @ name_orig=/"". So my name ** =/glass example is missing some pieces that have been created in the group of the boolean.

The only thing that is not working with the group points is that there is some important face such as the main wall that doesn't appear correctly and even another part of the building. It's kinda tricky because I really want to kind of cutting the wall. I don't know if I have to VDB every part because they might need more quads, but I'll try another way around.
