At first sight, LOD groups seem like they are great. Imagine if one were to have a scene where every single object has LOD Groups. Would this give stellar performances or would the large number of LOD groups actually counter the good. If so what is a reasonable amount of LOD Groups?
In my case I have a trench scene with many sand bags. Would I be better of having every single trench object be an LOD group or would it be better to group trench pieces into larger LOD groups.
In short, Is there such a thing as too many LOD groups? If yes, how many is too many.
