I've been working on the visuals for when things get completely destroyed and the plan is to have a bunch of generic wrecked shapes that can be re-used for different objects as well as rubble piles for smaller objects.

When something is destroyed, the plan is that there's a particle explosion of junk that hides the object being replaced by a wreck.  

Ultimately we want wrecks and rubble piles to eventually be actual resources, so you can salvage or sell the scrap.
But right now they're only visuals.

There's also a broken door there, which is how it will look after doors get blown up.
As for the flickering, it adds a lot to the immersion, but we're not sure yet where or how we'll use it.
