I have purchased Mesh Generator and used it quite alot around 6mths ago. I am trying to use it again now and my simple railing of 6 prims & 4 faces, when using the Mesh Generator becomes 17LI. Can anyone shed some light on why this would be happening. I have previously converted a gazebo I made that was 236 prims down to 35LI. So i was expecting a simple railing to come down to around 2 or 3, not go up to 17. Thanks in advance, Julya
