Morph Parameter Settings Help

Trying to learn how Daz works and how the morphs are connected. So the FBMVoluptous drives the Left and Right Pectorials.
- Does X Origin and End refer to a delta of the position of the bone?
- Are there additional deltas hidden somewhere in the morph, or does this morph only rely on the sub-components below?
- Do we need auto-follow only for clothing or other things that have to follow?
- What does 'as percent' mean?

and final question

- Is there any update on the documentation planned? It seems to be outdated.

    Those are not the morph deltas, they are adjustments to the named bones so that they are still correctly placed relative to the changed shape.

    If you want to place an uploaded image in the body of your post you need to leave the attachment, otherwise there's nothing for the link to refer to (you may still be seeing the image as you have a cached copy from the original post).

    Thanks for the reply. I tried to attach the image now. Hope it works...

    I really try to understand the rig and morph system used in Daz in general and used with Genesis 3 in detail. Freeze ERC delivers a list of [DeltaAdd] and I really like to understand how this works. I'm coming from Poser and I'm relatively new to Daz. I like Genesis 3 a lot and the quaternion weighting, as this is exactly the same system that is used in Cinema 4D spherical weighting. I miss some detailed technical explanation of the MCM and JCM system, as well as other things.The documentation at Daz seems to be a bit outdated or WIP.

    So the Origin and End thing is not a change of the position in absolute coordinates in space? If you say relative to the changed shape, what does that mean? The shape are polygons or vertices, or am I wrong here?

    DeltaAdd is a type of ERC link - it's called the same in Poser. It's not the same as the morph deltas, though in both cases dleta refers to a change in value.

    Consider the hand - if a morph scales it to make pianist hands, with extra long fingers, then when the fingers are bent the hinbge points will be in the wrong place. Using Adjust Rigging to Shape or by manual editing those points can be moved so that they line up with the morphed knuckles, then ERC Freze is sued to link the changes in the hinge points to the shape so that they move as the morph is set.

    So to get this right. The hinge is shifted in order to get it to the right place for the bending. Is the origin or the end the position of the hinge?

  • Richard HaseltineRichard Haseltine Posts: 102,716

    The origin is the hinge point, the end point may need moving too of course.

    Thanks again. So the hinge is the start of the joint and the end the 'end' of the bone.

    Yes.
