Soft Body Collisions

I’m having an issue with soft bodies as follows.

If cluster collision is disabled the soft body will become stuck in and slip through triangle meshes. If cluster collision is on, there is no such problem but the Mass physics setting seems to be ignored.

Is there any way to alter the mass of a cluster collision soft body? Or prevent non-cluster soft bodies from falling through the landscape?

Don’t use Loc and LinV for the movement use force.

I am. However if a soft body if smacked with enough force then parts of it will penetrate a triangle mesh and it will become stuck or fall through.

You can increase under advanced the margin. Or increase in the world options the physic substeps and (or) the physic framerate.

Margin is already pretty high. Physics are as high as they can go… well actually I guess I could increase the base frame-rate from 60. With recent optimizations to Blender and my game itself that might be feasible but I was really hoping for a way to have cluster collisions act as though mass were relevant. Cluster collisions work more or less fine except for that fact. Increasing the basic framerate is going to be a lot more intensive for other physics and rendering tasks which don’t really need it.
