SimpleScene falls through floor

Hi,

I'm integrating OgreODE into the Practical application without using framelisteners. I can get a box (crate.mesh) from simplescene to drop onto a floor plane successfully. I noticed the box mesh is of size 10x10x10 units so I tried changing scale of the boxgeometry. However, it will fall through the floor if the boxgeomtry is big (> 10)

This is my setup, which is mostly ripped from the SimpleScene demo, except where I scaled the box size.

// Create the ODE world
mWorld = new OgreOde::World (mSceneMgr);
mSpace = mWorld->getDefaultSpace ();
mWorld->setGravity (Vector3 (0,-9.80665,0));
mWorld->setCFM (10e-5);
mWorld->setERP (0.8);
mWorld->setAutoSleep (true);
mWorld->setContactCorrectionVelocity (1.0);
mWorld->setShowDebugObjects (true);

mStepper = new OgreOde::ForwardFixedInterpolatedQuickStepper (0.01);
mStepper->setAutomatic (OgreOde::Stepper::AutoMode_NotAutomatic, mRoot);
mStepper->setStepListener (&mOgreODEHandler);

// Create a default plane to act as the ground
mPlane = new OgreOde::InfinitePlaneGeometry
(Plane (Vector3 (0,1,0),0),mWorld->getDefaultSpace ());

// Create the visual representation
Entity * entity = mSceneMgr->createEntity ("TestBody", "crate.mesh") ;

SceneNode* node = mSceneMgr->getRootSceneNode ()->createChildSceneNode ("TestBody");

node->attachObject (entity);
entity->setNormaliseNormals (true);
entity->setCastShadows (true);

// Create a body associated with the node we created
mBody = new OgreOde::Body ();
node->attachObject (mBody);

//%%%%% THIS IS WHERE CHANGING THE SIZE WILL MAKE BOX FALL THROUGH FLOOR
// scale box
Vector3 size (50,50,50);

// this makes box bigger as box is 10x10x10
node->setScale (5,5,5);

mGeom = new OgreOde::BoxGeometry (size,mSpace);

OgreOde::BoxMass mass (10.0, size);
mass.setDensity (5.0,size);

mBody->setMass (mass);

// Tie the collision geometry to the physical body
mGeom->setBody (mBody);

// put box 100 units above ground
mBody->setPosition (Vector3 (50, 100, 0));

// In game loop, if step is using elapsed time, it will give assertion error
if (mStepper->step (0.01))
{
mWorld->synchronise ();
}


Practical application
What's that ?


// In game loop, if step is using elapsed time, it will give assertion erro
remove the assert in code or use another stepper, and report results here.

Practical application is the tutorial on the ogre wiki where there is no frame listeners events but a custom game loop

The assert (in the other thread) has nothing to do with this falling through.

I tried the QuickStepper, ExactVariableQuickStepper, ForwardFixedQuickStepper with time step 0.01 and same results. It falls through.

Did you try just modifying simplescene to use same big boxes, does it also falls through ?

No, I didn't. I don't have a simplescene setup cos I use the precompiled version of ogre.

Then do that first, so that you can find if it's related to your code or if it's an Ode or OgreOde problem.
