For my defence, I’m trying to reduce the load and we don’t have a bunch of 4K, though we do have up to a dozen textures on the really, really huge ships, those are things the size of Sajuuk you should never see in a game or fleet carriers that don’t get built in more than one or two. And even then, among these are common textures for all ships larger than a bomber.
Thanks for the vertices hard limit value, however, that will be a very useful info for my modeller!
As for my problem, I think I will try to bypass the issue by making the big go-through hangars of my carriers their own unselectable subsystem innate to the ship and then play with the collision mesh to make the whole thing work correctly ingame. After all, the ships with problems are the carriers, in which the hangars are detailed to hell (the original files come from a fighter space sim, so you spent some time in the hangars and could strafe them).
