I am trying to build a vehicle game, something like smash race in Dirt, you use your car to smash objects to take score. I have made the mesh to be destructible, and it destruct just fine. but the problem is, the debris are heavily affecting my vehicle movement. I checked online solutions and set the large chunk threshold super high, but still doesn’t work. the car is still bumping around by the debris.
BTW I tried to use a first person character to test it, the debris are not affecting the character (so I guess the large chunk threshold actually worked). Then I put the mesh in the VehicleGame project, it is also affecting the driving badly. so I guess it’s because vehicles is handled only by physics? Is there any other way to set the vehicle to ignore the debris? I can’t turn off the collision because I am using vehicle to smash the mesh.
Unfortunately the solution that I came up with currently has a blocker (pictured below). You should be able to just change the Collision Response Channel once the destructible mesh is fractured but that is not currently possible. We have it logged as [JIRA UE-7162][1]. I’ll update the JIRA to show that this is a blocker for you. You can follow that link to monitor it’s progress but it maybe some time because the issue is backlogged.
Thank you very much! Now I am using a work around to use another collider as trigger to trigger the destructible effect, when the car’s speed is high it looked ok, but when the car’s speed is low it look weird.
