Each CBB loads at the origin and is about twice the height of your standard human figure. Creating your own chedi is a simple three step process.

Load one of the four CBB as your base, scale it as required (do not move it at this stage), apply the morphs to get the shape you want, and apply textures/bump as required.

Load another CBB, scale it as required, move it vertically upwards so it appears to sit on the previous one, apply the morphs to get the shape you want, apply textures/bump as required, and when you're happy, parent it the previous CBB.

Repeat the above step as many times as required.

And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
