The terrain as you probably know will only have working collision if the mesh is sliced into 3x3x3 parts. 300pix x 300pix.
The hard part was always getting the parts to line up properly without seams etc.Most folks seem to have taken their slices into FPSC seperately as entities or segments.
If you slice up your mesh in your modeling prog(I use Max as you know but it should work this way in any.)The pivot point should remain at centre axis for all parts when you export each individual slice,this means when you bring them into segment creator they will align at the position and distance from the same centre and position as in your modeler aligning all the slices perfectly.
I have found that segment creator will bring in up to 55 slices,which you can export to FPSC as one single segment.Anything over this and it will crash on you,in the case of a 20x20 mesh there were around 110 parts so I had to move half of them 100 pixels so the two finished segments would match but not conflict when placing.
This may seem like a lot of work,and I know it probably is but for me there seems to be no alternative,Butter fingers has said that Maya's .x exporter does not have any collision problems with a complete mesh,but I dont think I could afford the 7,000 dollars for that right now
