This is for people who use the Original FUSE, before Adobe.
In the past, I personally have found it difficult to size things appropriately to CopperCube
CopperCube is easy to work with, but dimensions are best done BEFORE import
The theory here is simple...

• a. make a character in FUSE
  
• b. export the character in FUSE using the point zero nine eight (.098) as your scale
  
• c. make more characters for your story
  
• d. export them the same way
  
• e. import them into your 3D modeler of choice
  
• f. make the characters unselectable
  
• g. make your environment objects to the scale of your unselectable characters
  
• h. UV
  
• i. import them into CopperCube, save
  
• j. rig your characters
  
• k. export them into .x after researching a bit via a search engine (CopperCube supports many formats for importing basic 3D meshes, yet has very few format options for importing rigged meshes.)
  
• l. import your characters into CopperCube
  
• m. now you should have your environment and your characters of a scaled size that will work with the 3D models that are included with CopperCube

Good Luck.

I am not great at CopperCube, but as there are so few walkthroughs, I thought I could take a minute to put this up so people would find this part rather easy.
