- While going through my recently acquired huge pile of LightWavePro back
- issues, I came across Mojo's tutorial entitled "Missile Contrails Made Easy"
- in the March 1995 issue.
-
- Has anyone successfully performed this tutorial and gotten the desired
- results???
-
- I've tried to follow along on this tutorial and picked up enough to try a
- number of varations on it, but nothing works quite the way it should!
-
- I keep ending up with a missile contrail that has wildly bent parts in it,
- where one Bone's area of influence ends and the next Bone begins. I've come
- to the conclusion that it is totally impossible to pull this off with only
- three bones, as Mojo describes, but even with 30 or 60 bones following the
- same path, I still get undesired bends in the trail.
-
- The way the tutorial is worded is somewhat confusing...I'm not sure if the
- Bones' rest positions should be inside the missile itself, relative to the
- top, middle, and bottom of the missile contrail (which doesn't make any
- sense whatsoever) or if the three bones' rest positions should be placed at
- the top, middle, and bottom of the missile contrail, and then set to follow
- the missile along it's same path while maintaining their position relative
- to each other.
-
- The only way I was able to get marginally decent results was to use
- approximately 100 bones, all linked together like a chain, but not parented
- to each other...I then loaded the missile's motion path and offset each
- bone's motion by an appropriate amount. It worked (sorta) but it was a real
- pain in the ass and was a LOT of work for a not-so-realistic effect.
-
- So what am I doing wrong here? Has anyone else actually gotten this
- tutorial to work right or have you come up with a better way?
-
- Thanks....
