LOD limits?

How many LOD can I add to an object? Is 4 the max, or can you do as many as you need?
Also, is there a way a LOD object can be made to face the camera at all times, while it’s high res versions are normal?

For instance, if I had a tree in the very far distance, I could theoretically cut the super low poly version in half, or eve replace it with a mapped plane and only one side would facing the camera if it was far enough away, but as I got closer it would be swapped for the whole tree, which would stop facing the camera.


You the lod level is an int 32, so you can add 2147483647 lod levels.

And as for the facing LOD, there should be an option in the materials setting to have it always face the camera. It’s under billboard I believe.
