Change building lod distance script

change-building-lod-distance.cs

// Change the LOD distance of building assets. Run this script while the building is loaded in asset editor, then save the building
// It basically "fakes" a mesh in the basement, adds something to the building bounds in negative direction. 
// The game thinks that the asset is bigger and gives it a higher LOD distance


// maximum support value is 1000f, minimum is 250f
