   How to discover erronous data sets for Leafy BSPTree construction?
  Is there a way to check if a mesh is suited to feed it to a Leafy BSP Tree construction procedure? Are there any tools that pre-process the mesh and make it suitable for this kind of job or expose the parts that are wrong? I keep getting back leaves with all the polygon used as splitter on a level created by a friend of mine. I tested the algorithm on 3 small(<1000 poly) to medium sized(<6000 poly) levels and it worked, so i let's assume there's nothing wrong with the algorithm.
