i dont realy see any problems with the compiles they dont realy take that long, the limit of 2000 verts doest worry me bu i gess someone who does more moddeling would be the one to ask
i was thrown a bit by the fact that to convert the tags you had to put your first output into the input then run mode 4 but when u get it its not realy a problem
if you are updating the tool u might want to consider making it export the mdx differntly, now i belive all animation comes out in one file, this is usable its just harder to write the .anim files or whatever to pin point the exact frames but it loses the best bit that is were u can just take out one mdx and put in another
take this senario, u have all the animation of ur player in one mdx file, you have a bad walking animation near the start of the file, to modifly this u need to add several extra frames thus pussing th rest of ur anmation frame numbers up and all .anim files have to be updated. or you can add the animation onto the endthen you have wasted memory loading unused animation into the game
