Weird one. I have 3 vehicles in the level: a sedan, a 2 wheel robot, and a grey “fridge bot”. I used the sedan and robot from other places, so I did not set them up and they work correctly. I created the fridge in blender and imported to ue4. I copied the robot blueprint and changed the mesh to the fridge and put an instance in the level. Whenever it collides with the ground all 3 vehicles disappear from the screen. Here are the details:
- If I uncheck simulate physics I have no problem
- If I uncheck simulate gravity and hit it with the robot I have no problem
- If I start the fridge already colliding with ground but do not simulate physics then I have no problem
- If I simulate gravity and physics and the fridge collides with the ground THEN all 3 vehicles disappear
- If I simulate physics and gravity and the fridge collides with the robot THEN all 3 vehicles disappear
I have not done any editing on the files imported from blender, here are some screenshots
