Parented Props randomly not following figure

I wonder if anyone can help me predict when a problem is going to happen, and preferably why? A solution would be nice, but I don't want to ask for the world!

I have set up some favourite figures with hair and clothes, decorated with props for jewellery. The props come in three flavours, poser prop finger rings (from 2007 or earlier), primitive toruses for simple ear-rings and G8F props for a nose & lip piercing. The primitives and poser props I have placed in the figure tree intending to parent them to the appropriate bone on G8, and they do move with the figure as intended when the figure is posed. The G8F props have a node of some sort (identified by an icon of an 'I beam') that sits between the prop and the appropriate bone of the figure in the tree.

Anyway, I save the figure as a scene subset, ready to drop the set-up figure into any new scene. Then, in the new scene, I apply a library pose and.. in about half of the cases the poser props and toruses don't move to match the figure. And in about half of the cases they do. The G8F props with their 'I beam' node always move.

Can anyone enlighten me as to why, how to predict which poses won't move the props and - this would be really nice - suggest how I could create an 'I Beam' node so that I could convert the dodgy props into ones that behave like the G8F props? I suspect this is a very simple problem, but it has stumped me.

I am using DS4.11 - I have not upgraded to 4.12 because 4.11 is working and I don't want to 'fix' my system until it breaks... Unless I need to.

Regards,

Richard.

    So are the props parented to the relevant bone or not?

    The I beam is a Rigid Follow Node - a way to haev a parented node follow a specific part of a model as it poses and morphs without itself deforming.

    I think they are poperly parented - but because I am not absolutely sure, I thought the beginner forum was the right place for this query rather than nuts & bolts. 

    In the figure tree the problematic props are in the right place. I put the rings into the scene, and they were added to the bottom of the feature tree. Then in the feature tree I dragged the ring and dropped it on the figure part I wanted it to be parented to. The ear rings are below the ears in the tree etc. The finger rings move with the ring fingers when the hands are posed. The problem only ever appears when I apply a library pose to the figure, and then the rings seem to be left behind where they were. But it doesn't happen with all library poses, which is what seems really odd to me.

    Had it again last night. The finger rings stayed put in space but this time the ear rings moved with the figure as the pose was applied. The translation on the finger rings showed 0,0,0 for X, Y & Z, which is what they become when first parented to the fingers in the correct place for a ring, but, the display position was where they had been before the pose was applied. Very odd. It was as if DS forgot to update the finger ring mesh display co-ordinates as the pose was applied.

    Was it a plain pose or an AniBlock? Can you tell if it used Pose Control sliders on the figure or just bone rotations?

  • richardandtracyrichardandtracy Posts: 5,665

    A plain pose, I think, using the control sliders.

    Does it make a difference? If it does, then maybe the library pose uses both normal slider poses and bone movements. Being a relative beginner, I don't think I'd be able to tell the difference. The pose seems 'correct', by this I mean 0 translation and rotation of the figure, the hip translation & rotation moves the figure so the appropriate figure parts touch the ground (probably applied after the majority of the pose was created) & then all sliders create the pose from there. 

    Ah well, looks like I may just have to apply rings etc after posing to be sure.

    Regards,

    Richard.

    Bone movements would be my definition of normal, I wouldn't expect it to matter but it might. You could try the Bake to Transforms command from the Edit>Figure menu, see if that helps (it turns pose cotrols into local bends on the bones).

    I shall try this evening, thanks.

    Thinking about it, I am not entirely clear by what you mean as 'Bone Movements' rather than 'Sliders'. If by 'sliders' you mean combined movements like 'Left Hand Grip', then the poses are all 'Bone Movements'.

    Since starting this thread I've not had any more problems with the primitive torus ear-rings. I wonder if the problem was down to the finger rings being old poser stuff. I'll try modelling some new ones on CAD & do an entirely new model.

    So, thanks for your help, I'll just file this problem under '??!?'.

    Regards,

    Richard
