Hello
I don't know if this will work but when you export to .x file in milkshape via Direct X(JT) (near the bottom of the list) it gives you the option of scaling the model.
If you export the building out of 3ds Max as an .obj and import into MilkShape then you export back out of Milkshape as a .x file scaled to whatever is needed.
I know it sounds a bit of a messy way to do this but until FPSCR has the model importer working it is the only way I know to do it.
Unless anyone has a better way that is (I would also be interested)
I've got something to say
