I have been looking at the latest Bullet video from sidefx, and tried all examples which has the Bullet Glue SOP node, works fine, and looked at Jeff W example of the crumbling ground, and I can recreate that.
But, a big but, I need to use animated base geometry, think spaceship hitting a mountain side,
the space ship will be driving into the mountain, just the pieces that are flying of the ship should be active and fall to the ground, ship continue on its course (use animation).
When I do this using constraints, it works fine for 30% of the pieces, the rest goes crazy.
So for the spaceship example, I constraint the backside of the spaceship that is going to be the last to hit the mountain.
I am using a sop solver connected to the glue network constraint to delete parts of the glue network.
Cheers
