Panda Bullet

Hello,
I’ve tried to use an egg file as a map for a test, and … look at the screen shots:

The code i used for the map is:

	# Load the environment model.
		self.map = self.loader.loadModel("models/map")
		geom = self.map.findAllMatches('**/+GeomNode').getPath(0).node().getGeom(0)
		mesh = BulletTriangleMesh()
		mesh.addGeom(geom)
		shape = BulletTriangleMeshShape(mesh, dynamic=False)
		body = BulletRigidBodyNode('map')
		bodyNP = self.worldNP.attachNewNode(body)
		bodyNP.node().addShape(shape)
		bodyNP.setCollideMask(BitMask32.allOn())
		self.world.attachRigidBody(bodyNP.node())
		self.map.reparentTo(bodyNP)

Where is the problem ? Blender 2.63 don’t export (with Yabee) the blend file, but with export directx and x2egg, i can use it with panda. But is it possible that there is a problem with the geom ?

Here is the blend and egg files : http://www.benicourt.com/bullet/models.rar
