Need help

RudySchneider:
I got to thinking about parenting and independent relationships and threw together this short video for folks to ponder...

DFX2KX:
Nice overview, Rudy. I generally use the 'static mesh' method' when I have something that needs to match an already existing shape, and then cut it apart for things to move. but hierarchical building is a bit more flexible.

Anim80r lacks the sort of 'constraint' system that a mechanical modelling software would have, though (Anim8or isn't made for that, after all!), so really complicated things are going to be a mess all the way around.

Owl:
Need more Help, can only read the documentation and forum so long before signing in for a rescue.
Why in MODE>SCENE when a parent and child are selected and then displaced on a keyframe do they move different amounts and thus loose their relative locations??
If I select only the parent and not the child they do move together?
Thank You

PS: Maybe related, even though that say they are parent child, they are on the same line under World.

RudySchneider:
It's not necessary to choose both parent and child.  The child should "tag along" with the parent's motion.  Conversely, you should be able to move the child independent of the parent.  If you sel;ect both and move, you may get results you're not after.  Did you see what I posted here?: http://www.anim8or.com/smf/index.php/topic,5281.0.html?

ENSONIQ5:
Owl, think of the parent as the child's 'zero' location, and the child's position as being relative to the parent's position.  So, if you move the parent only, the child moves with it since its location relative to the parent hasn't changed.  If you move both parent and child in a single frame you are moving both the child's reference AND the child's position relative to that reference.  Any movement of a parent will result in movement of a child, but the reverse is not true, as RudySchneider pointed out.

One way to visualise parent/child relationships might be to think of your arm.  Your fingers are 'children' of your hand, which is a child of your forearm, which is a child of your upper arm, which is a child of your shoulder.  If you move your upper arm, your forearm, hand and fingers all move too since they are 'attached', even though you haven't flexed any finger, hand or elbow muscles.

Setting a skeleton in Figure mode essentially constructs a parent/child hierarchy, but for non-organic things (ie. meshes that don't deform) such as a robot arm you could assemble the parts in Scene mode using a parent/child relationship without using Figure mode at all.
