Niektb reported to me not long ago that my chinese buildings were having strange normal issues as you can see below. This as nothing to do with textures, but that means your AO is wrong. How can it be wrong. Well you maybe forgot to triangulate your mesh, or have too much UVs. The game reads the two first UVs of the mesh. If there is three, and the last one is the good one, that won't work. I also noticed that sometimes the game doesn't like the smooth option. So how to fix this ? Make sure you have two UVMaps only and that the mesh is triangulated correctly (To be sure, export it in the game and import it back) PS : If you never saw this it's because your graphics are not set to high. Search for the user cfg and replace the code by those lines : gentangents = "true"gpuskinning = "false"locale = "en_US"materialmgr.PARALLAX_DIST.max = "150"materialmgr.PARALLAX_HQ_DIST.max = "75"materialmgr.PARALLAX_VHQ_DIST.max = "0"materialmgr.quality = "10"particles = "true"pauseonfocusloss = "true"postproc = "true"preferglsl = "true"renderactors = "true"shadowpcf = "true"shadows = "true"shadowsonwater = "true"showdetailedtooltips = "true"showsky = "true"silhouettes = "true"smoothlos = "true"splashscreendisable = "false"splashscreenversion = "0"userreport.enabledversion = "0"userreport.id = "e012e183767f1423"vsync = "true"waterfancyeffects = "false"waterrealdepth = "true"waterreflection = "true"waterrefraction = "true"windowed = "false"
