i made a new map just to test out my new base model i made and the bsp is fine till you get to the bases then the points i place just fall through! what is going on!?!?

Spawn points you place? You spawn, and fall thrue? Or you spawn, go to the base, and fall thrue?

You put a spawn point in a scenery base? If so,
in sapien, uncheck Gravity
move the spawn point so you don't spawn in the base's floor/wall

or better yet, make the spawnpoint outside

no the base is not scenery and the points are falling through i cant get them to stay on the bsp! like hers my bsp -------------
point --> *

need more info
screenshots - transparent faces, no backface cull, visable edges
materials list

i dont know how to take screenshots of sapien and its just a flat ground in the air with 4 bases on it that wont stay on the bsp no walls or anything on the ground just 4 bases

in max, select your mesh(s), and do this:

Are the bases welded to the ground, or are they placed in max like you would in sapien?
If they are placed, I think you'd need to move their centers to zero, as depicted above
I got very little info to go on, so I'm guessing
