hallo, i´m doing a tutorial and have a problem.


it s not easy to explain the problem but i attatched a hipnc-file.


The tutorial is about generating a crack that goes through a grid.
there is a cookie sop that should cut a poly grid. but sometimes the grid explodes!!!!

can anybody help me?

Basically you're doing a boolean operation with a flat plane and that sometimes doesn't work (for a lot of 3D apps it rarely works). I just had to move the plane up in Y a tiny bit (0.01) and it worked.

Cheers

thank s for the fast reply!
yes, playing with the ty of the grid really helps!
i don´t not why but it is working now.

my fazit for today:
houdinis booleans seem to be situated anywhere between control and fortune.
that´s nice! i like random!!!

Yeah, it's about how faces intersect, it's never 100%. But it's not only Houdini, The best boolean I've ever seen is in a software called Form-Z that I used many years ago! That was a hell of a boolean engine! But other than that, all the other 3D software I've used fails once in a while…
