@sivan: yeah, me, too.

I also hope (for the future, no necessarily the next update) that they'll concentrate more on performace and usability / control of whats going on on a lower level.

So if you want to to change something or add some custom stuff to the rendering process
there's not very much you can do. In that case you'd have to rewrite the whole rendering
code on your own.
And besides that, I'm pretty sure that most of the Acknex stuff like ENTITY* and all the
move / trace / scan functions won't be compatible if you do so.

So in the end this would be just like writing your own engine...
