Freeze softbody in certain axis

[josemendez]

I want to have my softbody to fall to the ground with a fixed position, yet it moved a bit on X and Z axis.
Is there a way to freeze a softbody position in certain axis (X and Z) like in Unity's rigidbody setting?

Hi!

Yes, you can change any per-particle property using the provided API:

So you can project each particle position so that it doesn't move in a specific axis, or even stay on an arbitrary non-axis aligned plane, whatever you want.

Also how can I make all the softbodies to not interact with each other?
I figured out that I can use 1 solver for 1 softbody, but it'll bloat my scene with solvers, so is there any other way?

As far as you use one solver per softbody but the same updater for all those solvers, that's fine performance-wise. If you use separate updaters, all softbodies will be updated sequentially and will not make use of multithreading, which will of course result in worse performance.

If you want an alternative to using separate solvers, you can filter out collisions between softbodies using collision filters. See:
