there is some more thing i noticed: When I'm loading 3ds object and cycle trough all mesh elements doing: (loader.getChildAt(i) as Mesh).bounds.nullify(); model displays well after load but while camera is close to the model those triangles that are not in center of camera disappear (some clipping effect)
When I omit .nullify() and just add loader to scene, some of faces are not vissible but there is no clipping effect and during zooming camera (by lowering distance value)
