Subject: Hip movement independant of whole body?


Dowjonsie ( ) posted Tue, 10 March 2020 at 12:46 AM ยท edited Mon, 25 November 2024 at 9:02 AM

Blender has a way of creating an armature where hip motion can be independant of the rest of the body, yet confrom to its constraints, maintaining proper realism. Does poser have an option like this? It makea the already tedious process of animation so much more difficult, and a simple feature like this can REALLY streamline workflow. If it ia not natively possible, does anyone know of a tutorial for, perhaps say control props, that can make this achievable? Simply locking upperbody portions doesnt save face as most figures apparently come preconfigured with a hip as a parent to most the rest of the body. Perhaps maybe just making the chest or even abdoment the parent can help a lot but I am not an advanced user when it comes to rigging.

The hip actor is a child of body actor but it has all 6 degrees of freedom and all 3 schaling directions, so yes hip motion can be independent of figure(body) motion.

If you do a pose of a couple talking you normally keep the body actors at their original zero place and you move the hip actors to ensure relative position.

Sorry... maybe i need to clarify. When i say "whole body" i do not mean the body node. I know the hip can move independantly of this. By "whole body",i meant the entire body of the figure in question; ergo rotation and translation of the hip bone moves the abdomen and chest as if it were statue. What I am seeking is a means to translate/rotate the hip without mirroring the translation in the chest and abdomen. Say, as a belly dancer swings her hip, her upper body does not move in exact motion with it. It sways freely. Blender has a means of achieving this type of kinetic motion. I was hoping poser did, as well. I know i can, of course, pose the hip, THEN pose the chest and abdomen. But, again, i am looking for a means of streamlining this, to maintain the fidelity of the upperbody position withoit having to compare/contrast between multiple keyframes for an animation.

You mean inverse kinematics? Yes it is there, applies to hands and feet. The IK chain you mention is not normally implemented. I am not sure if Poser would support it but it is worth a try.

Check the manual about how to define IK in Poser. Facilities will be in the Setup Room of course.


Dale B ( ) posted Tue, 10 March 2020 at 6:46 AM

Be very careful with Poser IK; it is onlya partial implementation at best. Something like bellydance hip lifts can be difficult to keyframe, as you have to be aware of exactly what is going on. Most hip action starts at the feet, since that's where the weight is being supported, and involves all the joints up to the end of the lumbar chain.

This is an example of why I say we need a full IK/FK system. Poser only supports IK; with FK you could reassign a target at any joint, so you could designate the top of the belly bending as an anchor to get the basic motion down in hips and legs, then turn it off so the rest of the body is affected by hip action. As it stands now, if you animate with IK in Poser and then turn it off, you can have some serious issues, particuarly if you used quaternions. Although it can be amusing for others to watch your figure turn into a mesh knot monster.

Content Advisory! This message contains nudity

@Dowjonsie - Yes, it is possible as can be seen here (I think this is what you're refering to).

This is SASHA-16 with the whole figure selected, then you go EASYPOSING>TORSO>Hip Rotate X. You will notice that unlike other figures, everything above and below the hip stays vertical while the hip is rotated, very nice! Cannot tell you how it is being achieved as I've only recently installed her and she appears to have been created by some figure wizard who can do clever things with the Poser dials, but it does at least show that it is possible, which is not surprising actually since Poser is very powerful animation-wise under the hood (it's just got an atrociously clunky animation interface).

Its ERC. You can set that kind of motion up with say Netherwork's Spawn scripts; enable IK on the legs, rotate the hip, re-adjust the rotations on the abdomen and torso to default and spawn a master dial. Or some variation on that IIRC...

Dependant Parameters should be able to do that, I used them a lot when building my skeleton figure, it's a useful feature. I set up a series of nested dials that enabled posing and manipulating the figure without leaving the Body tab.

...I set up my missus figure with such dials that posed the figure, one of them being a tilted hip arched back pose. There's a lot going on in the dependency but you could just choose to slave only the hip rotations to the dial I suppose, I'd need to look at the script again.ex1.png

...or, as Caisson stated, use the dependency editor. I find the the Spawn scripts to be a little less convoluted. Same result though...

There is a simple way to achieve this option. In blender you mostly have a Pelvis and a Hip Ghostbone now if you want to have this option in Poser you will need to do it in the setup Room.

Load your figure " Doll " in the setup Room of Poser there you create a new bone in the body root of your Doll, Click the Body and place a Bone on the Hip level of the doll. Name the Bone Pelvis. you now have a Ghost bone. Drag and drop in the Hierarchy the Abdomen of the doll into the Pelvis bone. now the legs and hips are detached from the upper body.Drag and drop now the Hip into the Pelvis, go back to the Pose Room, Save your Figure.

you now have individual control for the Lower and upper part of the doll. Due the fact that the Hip never has been rigged you will have to make a little Adjustment with the zone XYZ influence between Hip and Abdomen using the Joint editor. not a biggie and should be done quickly .

If you wish to avoid the Rigging of the Hip then simply do the same steps as mentioned but use the Pelvis ghost bone to attach the Left and right leg. Pelvis on Body and hip on Body. the hip will not be used anymore setting limits to zero. you can add an other bone as Master bone that replaces the Hip function as ghost bone by having it linked to the Body and drop the Hip and Pelvis into it in the hierarchy. Toying a little around with ghost-bones will offer you incredible possibilities without affecting your Figure setup and basic functionality.

Note : doing such a setup will generate a new Obj file for your Doll that will be saved at the same place where you saved your Doll in your Library


Dowjonsie ( ) posted Tue, 10 March 2020 at 8:54 PM

No, i am not talking about an IK. An IK would move the hip only independant of yhe hands and feet.

I figured out a way, nonetheless. For those interested, its an extremely simple process. Spawn a primitive (select an object you are not trying to aninate), and simply click either the chest or abdomen, go to the object menu at the top, and plint the chest or abdomen at the prop. With an IK enabled, this will give a remedial means of mpving the hip independant of the entire body.

Lol so... i created a control prop for most actors. Thighs, upper arms, abdomen, chest, head, hips... its essentially an archaic and amatuer puppeteering setup but holy hell it works and so far has actually been much, much easier to animate and pose with than individually orienting each body part. The extremities i left alone because of my characters posing but if she were standing, id do those instead of the upper limbs.

One problem to have shown is when an IK is attached, parented child bones to a point at actor lose fidelity. I.e. chest has a point at, ik on hand DO keep their orientation, however the upper and lower arms do not follow the hand.

Edit: as suspected, simply pointing the forearm to the hand and upperarm to the forearm fixes an attached ik.

This is awesome. An amateur setup yes but this is just great lol

One thing I love about Antonia is that she has a separate hip joint just to bend the hip without moving the entire figure.

My v4.2 has a bendwaist morph. Im not entirely sure where it came from. I think either The Girl 4 or Aiko4. No matter, i will be upgrading to Genesis 2 since she is backward compatible with v4 clothes and hair (to my knowledge). Im going to give Carrara a shot with an import scene since it has a native poser scene loader and try animation in that program.Boni posted at 10:39PM Tue, 10 March 2020 - #4383190

Hello @Dowjonsie

I'm the creator of that figure, just back after a serious accident. To get the figure, look here:

sasha-16.forumprofi.de

Just remember the iron rule:

  • Never, ever, ROTATE a figure (any figure!) by the hip in the Y-axis. Use the BODY actor instead!
  • Also, never TRANSLATE (as in: move side-side etc.) a figure's hip. Use the BODY actor instead!

For more details why this is good practice please read the manual that comes with SASHA-16 to learn more about gimbal locks and actor offsets. After that, you'll have a much better understanding of how to pose and move figures in your scene without getting nausea...

Took her for a test drive and it is simply amazing. One problem i am having, however, is with an IK rig attached, her knees tend to bend in very odd ways, with the shin (not particularly the thigh) rotating a complete 90ยฐ at certain positions. Copying existing characters was a breeze, though. And her organization of morphs is robust yet concise. I was giving genesis 2 a test the other day and this has simply brought me back to generation1, again. I'll read the manual and see if my aforementioned problem is noted within.

I'llfigure it out. I thought i was being clever with my amateur puppeteering setup (which was working on a per load basis, loading a scene with "point at" actors ruins conforming figures until deleted) but this is simply amazing. KarinaKiev posted at 4:32AM Sun, 15 March 2020 - #4383600

Sasha is great, and I was really hoping for the male version as well. They would be my preferred realistic figures for some time to come.
