Does Unity support .BSP and .MAP files? In my knowledge, these formats are the best for low-poly collidable interiors/buildings.
These formats are the ones which use a specific spatial partitioning scheme (BSP tree) to render static (non-moveable, non deformable) indoor level geometry. Mostly used in FPS games, because they usually consist of static geometry and mostly indoors.
Unity does not use BSP partitioning, so there’s little use of BSP or MAP formats. Just give it your level geometry as a Maya file, Blender file, FBX file etc.
OK thanks. The reason I was wondering is because BSP and MAP offer extremely simple collision meshes, making them very fast to calculate.
