do you want to see through the window into the plane?  if so, did you
model the inside?  what is the box in step 3?  i haven't used udos
much.  are they solid?  so you have three copies of the udo?  it seems
like you should be able to do it cleaner.  answer the above q's and i'll
see if i can help.
