I am just using the plane mesh for now. I am using ApplyLinearImpulse to move a ball (sphere shape) forward. With the mesh collider on my plane, the ball hits the inner edges and bounces up a little. I have set Restitution to 0 for both Physics Shapes, and it's minimal but still noticeable. I also have linear damping set to 0 as I want my ball to free roll. It appears as if it's hitting the edges. Almost as if for a moment in between faces, it drops down due to gravity for a fraction and gets knocked up again. problem worsens with velocity. Anyone know why this could be happening, and even better a solution?
