Randomly passing through RigidBodys

Troubleshooting physics
1

Hi guys!

I’m working on a jmonkey game and i’m using bullet’s native library and i have a big problem…That’s the code i use for map’s spatial and physics:

        //Terrain geom
        Spatial map = getAM().loadModel("Models/map.mesh.xml"); 
        map.setLocalScale(100f);

        //Terrain Physics
        terrain_phy=new RigidBodyControl(0f);
        map.addControl(terrain_phy);
        bulletAppState.getPhysicsSpace().add(terrain_phy);

The problem is that sometimes the player can pass through the map just like it has no physics and maybe go under the world,and then while(true) fall;

Here’s a video: - YouTube

This happens randomly an i can’t understand how this bug works. Does somebody have my same issue?

I guess your terrain have really large triangles which does not work so good in Bullet.
