Please make yourself familiar with the basics described in the introducing chapter. You need to know them when using Blender to create objects to be used in the Warper or in Pandoras Box. Even more detailed information can be found in the Warper's chapter "General 3D Modeling Terms".
To set up generic units in Blender, usually you do not have to do anything. The "None" setting matches the generic unit already. In the same dialog you may adjust the camera to match Pandoras Box' camera.
If you like to learn how to generally create an object and how to apply an UVW Map, please refer to the chapters in gmax.
The next chapter describes how to create and export objects in Blender.
