How to put destructible meshes to sleep?

Hi there,

We are creating a game based on bunker destruction. The whole scenario is destructible. I’ve used some tricks like replacing instanced static meshes with its DM counterparts on damage, but I have a problem with the visual feedback on impact. The impact “activates” the DMs and hide the statics, but doesn’t really “hit” and break the destructibles correctly.

If I use directly DMs, the collisions work fine and the feedback is awesome, but the game freezes really fast due to the great number of collisions of the chunks on scene. We already optimized the game removing unnecessary DMs and using the replacement trick, but I am struggling to get the good feeling.

The best solution would be to use directly destructible meshes, and put their (or at least the chunks) collision to sleep until it gets hit or damaged. Do you guys have any idea how to achieve this?

Thanks in advance!
