I’ve been wondering if there is an easy way to fade out small objects or other objects depending on your distance away. I don’t think it’s to important to render little tiny mushrooms, boxes, or other small objects if your really far away. I’m getting way to many draw calls if I’m staring at my town that my frames drop very low. Even though all my models are pretty low poly. Any good techniques for optimizing my scene that has a lot of gameobjects?
Unity 3.5 will have a LOD system for things like this. With Unity 3.4 you can turn off renderers yourself based on distance.
