how to reduce bounce effect

Unity Engine
1

I’m trying to land an aircraft(spacecraft, for this instance) on a runway.
The problem is, it bounces the hell off it as soon as it touches it!
I’m using icy physics materials on both objects, so the bounce is 0 and combination set on “minimal”.
I tried adding more mass, i thought maybe if the object was heavier it wouldn’t bounce so hard, but it just didn’t work.
Is there anyway to reduce the bouncing without scripting the whole thing using Kinematic or Trigger?

Some questions which may help determine the problem.

  • What are you using as colliders for the space craft and runway?
  • Are you using 1 unity unit per meter as your scale?
  • What is the velocity of the spacecraft when it hits the runway?

The runway should set be kinematic = true as I’m assuming its a stationary runway.

Webplayer would be nice…

Are you using forces, torques?

There is also some bounce setting in Edit / project settings / physics…

the runway is not a rigidbody, but its parent is SUPPOSED to be a rigidbody(currently isnt)
the runway is a box collider and the spacecraft is a mesh collider, but its GEARS are box colliders
im not sure about how to check to scale
the velocity’s square magnitude is 78 point something, cant remember specifics…and i dont remember if its the normalization that i need to check or the square magnitude…

im using forces and torques, as the spacecraft is a rigidbody
the bounce threshold isnt relevant right now, because i dont want no bounce at all, i just want to minimize it…

Is there any Drag on the objects?

With 0 drag, even the smallest reaction (the act of moving the colliding objects apart so they no longer collider) can cause them to launch apart. Try with some drag on the ship to see if that improves anything (though the ship itself could act a bit odd at this point).

the ship has 1 drag, ill try setting higher values, see if it works

EDIT: it works, but as you said, the ship’s acting wierd…and i have to multiply the force by the drag
plus, it doesn’t give me the effect i want, i want it to bounce a little then land back, but this time with less force, the problem is, that there is no decrease in the force, so i just get all the screen vibrating insanely…
