I have an octree sort of thing, but I can''t figure out how to keep my engine from drawing an object over again if it finds it in many nodes, a very large wall would do this for ex. Would you just have a draw tag on EVERY object, cycle throught each object and if it has a true value in the draw var then draw it? I just can''t think of any other way to do it. Is the previously mentioned example really how you do it? Thanx ahead! Zach Dwiel ~ Tazzeld
