Hello! I'm building a mesh single object three floor house 32x32x15 and I need cubic physics for it. All walls have own cubic phys (27 cubes total). There are gaps between them. But the physics that I made when uploading a mesh into sl w/out analyse is for some reason used upside down. The door hole is on the top/roof, the floors are parallel to the walls ... I'm confused. Please tell me why this is happening and how to fix it? I tried to spin the house and physics in a blender but it did not help. Thank you for any help!
