Conveyor Renderer System by No-Half-Measures
This is just a simple demo of rendering conveyors and moving meshes along them to give the impression as if the conveyor is pushing the Items along with physics when it is not.
When Conveyors are abouve a certian distance from the camera the animating of the meshes is less frequent and at larger distances they don't animate they just appear/jump to their next slot, This is to reduce the cost of calculating this when you have much larger numbers of conveyors on screen.
The overall effect is that you can have hundreds of these on screen at anyone time with little performanc impact.
