Feedback Cloth jumps when 'Pausing'

[josemendez]

Hi there,



When pausing our game (we set our timeScale to 0) and reset it back to 1 when we unpause. We seem to have an issue where the cloth receives impulse and ends up jumping every time we pause and unpause our game.



I've attached a video where the main character's gown ends up jumping up. I'm wondering where I can take a look to start debugging this issue with ObiCloth?

Hi Porrith,

Tested this on a character cloth setup (setting timescale to 0, then back to 1 to unpause) but couldn't reproduce this ourselves.

My guess (bit of a shot in the dark) is that there's some constraint the particles are violating while the game is paused (collision or skin constraints are most probable culprits) and since the simulation is not advanced while timescale is set to 0, when unpausing the game the particles are instantly forced to meet the constraint causing them to jump.

If using them, try disabling your skin constraints and see if this improves. If it does, look if there's any chance the character animation might be running while the game is paused (for instance, if your animator update mode is set to "unscaled time").

kind regards,
