I started playing with oolong engine http://oolongengine.com/ I had some issues in mixing my code with the engine but
everything looks ok now .There is a lot of usefull stuff and most important it is free!!!
I ported my doom 3 model code ,something is f..ing wrong with the texturing also I need
some kind of material file loader also in order to load the textures per mesh.
Horrible horrible zombies with crapy texture code
The next step is to load doom 3 level geometry (proc files bsp portal stuff) Ill move my dx code to iphone.
