CJH_Lod90-Fixes.zip (47.1 kB) contains some Lod90 (Neighbourhood View) fixes from A&N, the one named TriumvirateMouldedBelt-Lod90Fix.package is the one you want. There is two of those corners and Maxis has muddled the Lod90 meshes from A and B up, that file just renames them so the game uses the correct one. You won't need to do anything, once the file is in your game your building is instantly fixed.
The other files (note some may not work well with custom re-colours);
PlayGround-Lod90Fix.package, Maxis included all of the re-colours for the playground equipment in Apartment Life but failed to link them. For this to work you will need to enter and re-save the lot.
WindowBayEmpire-Lod90Fix.package, fixes the Lod90 colours of the M&G bay windows. For this to work you will need to enter and re-save the lot.
WindowBayStorybook-Lod90fix.package, adds a Lod90 mesh to the Storybook bay windows so from neighbourhood view they don't sit flat against the building any more. For this to work you will need to enter and re-save the lot.
