  18. : I got the tutorial to work, but it took me an afternoon of playing with
  19. : numbers.  One thing that that LWPro forgot to mention was that the texture
  20. : sizes for some of textures needed to be increased, especially the
  21. : displacement mapping.  Sizing just the bones just doesn't cut it.  Also,
  22. : since the object was built along the Z-axis, that was the fall off % that
  23. : mattered the most as to the trial fading out.
  24.  
  25. I had no problem getting the Displacement Map textures to look good...the
  26. problems I had were with the Bones themselves...each part of the contrail
  27. that was being affected by a bone was "stretched" away from other parts, so
  28. if I used 3 bones, the contrail was broken into 3 distinct parts with very
  29. thin "stretched" pieces of the contrail connecting each part.  (I hope this
  30. makes sense!)
  31.  
  32. I'm wondering now if the Bones should have had Limited Region turned on?  I
  33. don't recall reading anything about that, but this problem seems to be
  34. occurring because each bone is influencing too large a section of the
  35. contrail.
  36.  
  37.  
  38. Here's an attempt to show what's happening to my missile contrail, note the
  39. "stretched" parts of the contrail between each bone's region of influence:

  57. It's been at least a week since I've played around with this tutorial...
  58. maybe it's time to tackle it again with a fresh perspective.
