    Newtek...Where are they?

    I see some stuff for expressions on your tut site,
    specificaly this :

    MBLightWave 3D Expressions Part 1: Nuts And Bolts

    Are the other parts somewhere else (not on that page and no links to other pages there).

    I need to learn this and that first part was basic enough for even me. BUT I need more!!!

    I can't speak for anything currently being developed for our site, but you might want to try LightWave Tutorials on the Web: Expressions/Sliders/Motion Modifiers

    All statements to the effect of this parrot is still a going concern are from now on inoperative. This is an ex-parrot.

    K, Thanks


    Looking for something that should be really simple to do (cept for me)

    Kinda like ;
    If bone 1 rotates 90 degrees then bone 2 rotates half of 1s degrees.

    But I have brain implosion when it comes to this stuff.

    on the second bone you could do this expression:

    [firstBone.Rotation.H] / 2

    See ??
    That's why your name says 'Super Genius' and mine only says 'Member'

    So if I read this correctly;

    I need to put an expression on what I want to have result to be and *not* the driving bone?

    And I can change the H to another channel? Or direction?

    And I can do this even if the bones aren't even close in the skeletal system?

    Now...where does it go on the second bone?
    I mean where do I put this info?
    Same channel?
    Or can I do another channel to rotate second bone 90 degrees on Y and half the amout that bone 1 moves?

    Hmmm, gotta set up a 2 bone scene and play with this.

    right.

    Yup.

    And I can do this even if the bones aren't even close in the skeletal system?
    Right again.

    Now...where does it go on the second bone? I mean where do I put this info? Same channel? Or can I do another channel to rotate second bone 90 degrees on Y and half the amout that bone 1 moves?
    You put the expression on the channel(s) you want to affect. Getting 90 degrees plus half the rotation of bone 1 looks as you would expect:

    90 + [firstBone.Rotation.H] / 2

    Or, you can get the keyframed value plus half the rotation of bone 1:

    Value + [firstBone.Rotation.H] / 2


    Hmmm, gotta set up a 2 bone scene and play with this.
    as they say in gaming: GL. HF.

    Well, no matter how I try to put this stuff, I get the same errors.

    Blue bone is bone01
    Yellow is bone02

    I highlighted the channel on bone02 that I want to effect
    then I wrote the expression (making sure that caps and everything was exact)

    and I get the error in pic.

    ARRGGGG!

    i'm not an expert on this stuff, but i think the bone is only accessible via the object it belongs to so you might have to do something like:

    [myObject.Bone01.Rotation.H]

    [firstBone.Rotation.H] / 2

    That was your example

    This is mine
    [Bone01.Rotation.H] /2

    except for name of bone it *looks* the same to me

    Yet when I rotate bone 1 nothing happens to bone 2, no matter which way I rotate it (figuring I might have got the wrong channel)


    It's ONLY 2 bones!!!!
    what is my brain NOT grasping???

    Prospector:

    Just curious, have you tried Amelie Visual expression editor. It makes such as this much easier, for only $49.

    You need to prepend the name of the object that the bone belongs to:

    [objectName.boneName.Rotation.H]

    that should get rid of the error.

    No, I didn't know about it..

    Usually when I saw the word expression, I went screaming away from the computer.

    But I guess it really pays to learn this stuff, so I'm back.
