For physics actions it’s really important to have good static meshes, velocity, damping and collision settings. It takes a lot of work to fine tune the settings. If something weighs very little or a lot or if it has a lot of allowable velocity weird reactions can happen. If you limit the velocity of physics objects they tend to react better as well as if you set a lower friction coefficient material so things react more normally. Destructible meshes are a lot of fun and would be good in a puzzle game, there’s actually a lot of potential with controlling damage spreading (objects can be hidden inside destructible meshes, on top of destructible meshes or whatever you can think of).
