I have a helicopter mesh parented to a invisible cube that has all the movement and such. I made it so when the chopper is killed, its mesh is replaced with a destroyed helicopter mesh and it removes its parent. I tried making it fall two different ways:
1 - Replace physics with the replacing mesh brick.
2 - Just making the helicopter mesh dynamic ghost. Hoping it would fall when the parent is removed.
Both of these didn’t work. It just sits in the air, collisionless.
You could just End Object the aircraft mesh and Add Object the wreck mesh. This way the physics, the collision mesh and all that stuff is setup correctly in one go.
