Seems like it doesn’t matter, once you have set the sleep family to custom, you can set the sleep threshold multiplier with a 0, 0,0001, 500, 9999999 and it doesn’t change the fact bodies will sleep after being completely stopped, and it doesn’t matter the sleeping bodies are constrained, it will just ignore all motor forces, so if you are simulating breast, arms, belly, thighs, anything that could be simulated to add realism, and at some point the character is stoped for time enought to let bodies stop moving, chaos will put these to sleep, they will be stucked in the air for ever even if the character walks away.
The only workaround I have found too is using wakeAllRigidBodies function every tick…
