Gotcha, so from what I've understood when it comes to rock/mountain LODs one size texture fits all, the main mountainslab02 texture is used regardless of distance from the player, so any downsizing would affect every rock/mountain in the game (which leave's me wondering why there's even a LOD texture if the same full sized one is going to be used over and over). Just one little thing, you mention at the beginning that this is for rock/mountain meshes LOD4, if I were to select Static LOD8/16 in the LOD4 column would this have an effect (again if there's no corresponding LOD8/16 mesh I would see why not)? Sorry if this betrays a complete lack of understanding of how this actually works but I'd rather more objects in the distance at the expense of texture quality than a few gorgeous mountains that I can't really see in game. Thanks again. Edit - as for your second reply the main and LOD textures are from the same mod so no colour change when entering a new cell
