Add new sprinkler_model prefab that has two set of renderers: one for skinned meshes and one for normal renderers - reduce skinned LODs from 3-> 2 since the AnimatorLOD will turn off the renderers once they are past 25m (meaning it will switch to placeholder renderers) - reduce unskinned LODs from 4->3 since the 4th LOD was messed up (still hide after 100m)
