I'm trying to get a custom entity to spawn but it's not showing up at all. 
  
http://pastebin.com/8uKFxqVY - BaseMod - I've registered the entity according to this tutorial:

http://pastebin.com/f5LA5Khf - CommonProxy - Nothing here really 
http://pastebin.com/gSCre6wj - ClientProxy (maybe something to do with using RenderLiving instead of RenderBiped?) 
http://pastebin.com/CfkXXiDP - EntityUndeadKnight 
http://pastebin.com/zBg2QZvz - ModelUndeadKnight - really just a zombie model with the left hand down 
  
I really have no idea what's causing this, as I've checked every tutorial I can find... 
  
EDIT:  When I run start_client.bat it doesn't crash or anything.  The entities simply don't show up.   
'NOTHER EDIT: Also I didn't mess up any of the base classes so that's not the problem.
