how to freeze bullet objects?

[kleer001]

It's simple, right? Maybe a sop solver or a modify data dop ?

 

Check out the scene, it's fast.

At about 1600 frames in everything starts to slosh around then it freaks straight out.

A RBD auto freeze node may help.

Nope, that's only for RBD objects, not Bullet objects. Different solvers.

 

In the bullet object there's an "Enable Sleeping" checkbox with a linear and angular threshold, but they don't seem to do diddly squat for me in this particular sim.

 a quick hack might be to make inactive any objects older than a certain threshold.  Either that or start playing with oversampling on the dopnet or some of the accuracy settings on the bullet solver.  I've attached a way to do it using packed objects and a sop solver.

thanks bro!

 

I spent a few minutes with the manual and found exactly the same solution. Funny thing that, instruction manuals. Ha!

or you can use the length of velocity to turn off "active" in sop sovler,like this:

if(length(@v)<1)

@active = 1;
