Trimesh falling thru

Any idea? The trimesh sits on the terrain created using TerrainGeometry. Have changed the weight from 5.0 down to 0.01, it still falls thru. Below is the code:

OgreOde::Body* body = new OgreOde::Body();
node->attachObject(body);

ent->setNormaliseNormals(true);
// Set the mass and geometry to match the visual representation
OgreOde::Geometry* geom = 0;
OgreOde::BoxMass mass;
Ogre::Real massReal = StringConverter::parseReal(valueMass);

OgreOde::EntityInformer ei(ent, node->_getFullTransform());
geom = ei.createStaticTriangleMesh(mWorld->getDefaultSpace());
Vector3 size = ei.getSize();
size *= scale;
mass = OgreOde::BoxMass(massReal, size);
mass.setDensity(5, size);
body->setMass(mass);
// Tie the collision geometry to the physical body
geom->setBody(body);


The thing is, the collision went fine if I replace the trimesh with primitive box collision.

strange, as test_heightfield works with trimesh.
did you try with a bigger trimesh ?

I have tried it with gun.mesh (mesh supplied with demo), it still falls thru. But I am not sure with the scale though.. I will have to double check and will post any progress.
