I found this in the source-codes of irrlicht:
"Warning: The BspTreeNode is not bug free yet. Use the OctTree instead."
I plan to design and make some complex levels, so i should go for the OctTree renderer in irrlicht ? what would be the best format for my level to load it in irrlicht ?
Also, i would like to know if anyone has made a custom scene node renderer which is more complex than the one in the tutorials. Rgiht now i am trying to find out if its better for me to make a custom renderer in irrlicht or just make my levels and store them in a format and let irrlicht render it with an octTree. I dont like to go with bsp-format for many reasons. I want to make some levels which have very easy structures like hallways in dungeon master. From then i would like to extend my level-structures and enhance it more once i am more familar with irrlicht. The point is i dont want to do arbitary levels and want to restricts my structures so that level editing become easy. Another example could be doom2-like 2.5D level format and let irrlicht render it.
