you could offset the camera and the position of the points so you can only see the lidar effects.
sm.camera.setCameraState(3) -- the camera changes only happen in this state
sm.camera.setCameraState(1) -- reset to default

sm.camera.setPosition(sm.vec3.new(sm.camera.getDefaultPosition().x,sm.camera.getDefaultPosition().y,sm.camera.getDefaultPosition().z - 10000))
sm.camera.setDirection(sm.camera.getDefaultRotation() * sm.vec3.new(0,1,0))
make sure to use sm.camera.getDefaultPosition() when getting the player's position in other parts of the code.
