[Bullet]Fast objects crashing through my level bounds

1. Is the ship a kinematic body?
2. If yes, have you disabled deactivation?
3. Are you using the provided "car simulation" code?

I was performing some search and found this thread.
Perhaps I'm going to ask you a trivial thing but...

1. Is the ship a kinematic body?
2. If yes, have you disabled deactivation?
3. Are you using the provided "car simulation" code?

I'm glad you found it! ;)

1.: No, it's a normal rigidbody.
2.: -
3.: Nope, I have written one myself, using the scripting feature of our engine. The whole thing is a raycast vehicle which moves around by applying forces.
The script is a bit messy because of the tests I had to do, but I'll clean and post it if it's needed.

Do you use the same mesh for collision that is rendered?

What kind of time-step size are you using, and is it fixed? [/quote]

1. No, the collisionmesh is much simpler. I also tried the whole thing with a simple cube, and it happened there as well.
2. I can't really answer that question, because I don't know which timestep you exactly mean. Bullet uses an internet one as far as I know. Here is my Update()-Function:

/** Call this to update the physics */
void BulletPhysicsEngine::Update(float DeltaTime)
{
if(ThreadWork.bRunSimulation)
{
const boost::mutex::scoped_lock sl(ThreadWork.SimulationMutex);
GetDynamicsWorld()->stepSimulation(DeltaTime, BULLETPHYSICS_MAX_SUB_STEPS);
}
}

DeltaTime is usually around 0.02ms (0.00002). I run my rendering in a seperate thread, that is why it is so low.
BULLETPHYSICS_MAX_SUB_STEPS is left to the default value of 1. The fixed internal Timestep value is as well left to the default.
Could you recommend some settings for this to me?
