Anyone got any links to a good Joint Morph Tutorial?

Depends on what you're looking to do... joint morphing in LW isnt particularly straight forward.

I'm about to start testing importing characters into Unreal
that utilize morph targets. Ideally I wanna be able to just
import a control rig and not have to worry about extra bones
being used just for deformation purposes.

FYI, I'm using Joint style bones. (just in case someone has a good reason why I shouldn't)

And I'll be using it for the basic joint areas like knees and elbows.

In which case you'll need to drive the morph channels directly using expressions so that they can be baked properly for export.

Ok, so I got it to work somewhat using expressions, but it is moving before bones.

Is there a function that I can use to tell the expression to apply the morph after bones?

joint morphnig needs to happen before bones, otherwise it wont work under parent level transforms.

The morph seems to be morphing ahead of the bone rotation
and I did use the mapRange function. Maybe I don't need any
any bone influence since the morph is driven by the expression?

I'll post the file when I get home if I can't figure it out.

So if I turn the bone strength to 0, the morphs
beginning and end frames are shaped correctly
but the transition from start to finish is wonky.

Thinking maybe I can create a morph for Mid
Transition to fix the wonkiness between the
beginning and end frames, But, it doesn't
seem to wanna let me append another morph
to the expression. Is there a way to do so?

This is my current expression

You havent created a compensation morph... youve just stored the pose in the morph. You cant perform taht kind of rotation movement using a morph, because the transition is linear, no matter how many in betweens you add, you'll still get the same behaviour between each of those. Go back and see the vid I posted in the thread I initially referenced... its the ONLY way to do this correctly.

I'm assuming that you mean the second part of the video
where you use EditFX. So if the animation is 30 frames,
then I need to create a "compensation" endomorph at
frame 15 using EditFX?

Wouldn't that be like just creating another morph or is
EditFX keying it to that frame?

Lightwave 3D group need proper tutorials....................

No... the first part where I show how to get a comp morph modeled that behaves properly with bones. And no, you dont need to create a fix morph at the mid point... you need no morph at the base state, and a fix morph for the bent state. yours isnt a fix morph, its a "bent" morph.
