Hey gap ! That's working just fine !
Destroyable zone linked to the propeller "texture" (moving), without collision sphere. The spawned propeller (not moving) is in a library file.
Now, I remember why I gave up with this. I wanted the propeller to be destroyed when the engine was destroyed (non destroyable zone with a spawned fire). So I created a link between both. So when the engine was destroyed, the propeller was supposed to be destroyed too, and the unmoving propeller was supposed to be spawned. But that didn't work.
About bunkers, maybe a chain reaction could be created : when the "concrete type" zone linked to the bunker is destroyed, then a model of a little destroyed bunker is spawned (also with a concrete zone). If this new model is destroyed, then another model of a more destroyed bunker is spawned. Etc.
