Alright you two quit over complicating this thing.:tt2:

If you want to make clothes in Blender for V4 as an example.

Open Blender.
With the cursor in the 3d window press the 1 on the numberpad.
Import the V4 mesh from the geometries folder.
Right click on the V4 obj.
Press S and enter 10 to scale up 10x.
Press the decimal point on the numberpad.
Split off a new window and set it to Outliner.
In the outliner window click the cursor symbol to make the mesh unselectable, this prevents moving V4 from the default position by accident.
Save this set-up as V410xBase.blend or some such so that next time you won't have to do the above steps.
You are ready to start making clothes.
When the clothes are modeled, mapped, etc. turn selection back on for V4.
Select the clothes objects and the V4 object.
Press S and enter .1
Select and export the scaled down clothing mesh as required
