Hi, Your COL file is too large. I mean not in filesize but in scale. Must not go above 512,512,512 Generic units Inches in 3ds max.
Import the COL file back into 3ds with Kams scripts, notice how all the too far geometry is exploded on the side. Well I guess its that, hope so. Next time create a box of size 512,512,512 each COL files should fit in that.
