Theres a Physics problem killing the framerate...
Also, everything you see is an entity, with allot of polys, jammed together... The killers are the boxes that are falling through the floors, something wrong with Newton setup... Im also very curious how the framerate is going to hold up in A6, hopefully soon you will have your own examples
I updated the demo, the model is smoother, the junk you see is the slapped on texture... I'll make something better...
hourousha - I'm not tool designer, But I will link to all the needed tools. There are so many ways to make Normal maps, and many tools...My technique just makes them work with 3Dmax... Hopefully others will adapt methods for various modelling programs...
