HI,
I am not sure I understand your problem; I would think that using the proper bsp tree with the traceline/tracehull function provided by the HL SDK should help.
The trace functions in my Bspview have been coded starting from quake, but the tracehull provided in my code is not as accurate as the one available in the hlsdk. I do NOT use my code of my Bspview trace for tracehulls; in other words , the source code of my bot uses only hlsdk functions.
Endly, remember that for collision checks, the first ( word) bsp tree is useless; if you want to use directly bsp tree in your code, you must select one among the three others, as they represent a different geometry than the first one ( ie if I remember well, they include blocking brushes/faces which are not included in the word bsptree because this one is used for drawing).
PS sorry for the unanswered email, but I had ( and still have!) a problem with it.
