How to keep active pieces of pieces go out of bounds with RBD configure.

[pac]

Hi,

I'm looking for ways to activate and keep active pieces from RBDConfigure with active use bounds on.

Here, I have a tentacle come out of the ground, the bounds its my tentacule its self, first bounds active the closest pieces. But a few frames later, The active pieces that go out of bounds become inactive again.

This is a ways to force to keep active ?

Thank you

Try to use a trail for tentacule with preserve original option to make a trail of geometry. And don't forget to calculate velocity for a collision geometry.

Hi Paul,

Thank you for your answer. 

Yes, I was expecting that technique as well, and it works well. I will test if it works with a more complex setup.

Thanks.

Keep in mind, bound method based on packed primitive centroid location, it can be not accurate in many scenarios. Better way is to activate based on volume intersection. Check an example.
