simulation with maya fields

[Louis158]

Hi I am destroying a wooden house using dmm and having problems with the dmm shapes/tets stretching. Its almost as if they're exploding across my scene and then falling out of the simulation. Does anyone know how to prevent this?
many thanks.

This is a serious issue with using fields and DMM i believe it is caused because the tet meshes are affected throughout by the field not just on the surface and a big enough difference occurs that causes stretching(blowups).

some guidelines are
use passive colliders when you can to create the movement.
If you need to use a field do not try to break (fracture) your tets using a field, only use a field when you have a decent amount of fracture in place already.

you can also, if you only have a few, after Alembic cache or geo cache keyframe the offending tet out of camera view or into a zero state scale

good luck
