What are LOD Meshes?
LOD means "Level of Detail". With LOD meshes you can control the amount of details seen from certain distance. This is incredibly useful when you have a lot of cars in the distance, as it helps performance by giving you the ability to reduce the polycount by making less and less detailed meshes.
So basically this is how it should work:
-When you're close you can see all the details
-When you're a little further away, some of the smaller details (things like interior door handles, etc) can be removed, certain features could be made with less polygons
-When you're very far, even more details can be removed, the mesh could be low-poly.
In some Torque games there are settings for the mesh detail, but I haven't found it in Blockland, yet.
I better stop digressing now.
