    The FK IK snapping problem.
    https://prnt.sc/ugqmsas0V7bB

    This is a problem for me, when I want to work with IK and FK.

    Strech is 0
    Limit is unthick.

     

    The last problem I mentioned was still all in Blender environment.
    About the feet and arms that can't stay put, I try to recreate it again.

    Ah, I saw the moving which I also encountered the similar issue. Pls try ticking Pole Targets when rigging to MHX, which can enable perfect FK/IK snapping.

    @James I can't reproduce the issue with snapping, it works fine here. You may need to update since I recall this issue was solved a while ago. The actual MHX version is 1.7.4.0111.

  • crosswindcrosswind Posts: 9,548

    The snapping issue can be easily reproduced with default MHX rig with no Pole Targets activated...

  • PadonePadone Posts: 4,002

    Nope, tried without poles and works fine here.

    my steps:

    1. import G8F and convert to MHX
    2. pose the hand with the IK control and keyframe
    3. snap FK to IK then IK to FK multiple times, nothing moves

    Thanks, that was my key finding as well... but pls try with G9 in Blender 4.0+ if possible.

    Here's a quick video - https://mega.nz/file/KaAQFAgA#7f8COWa3s74S2ZlOCTl2qXGoMeY9dZF2KEmfV4mdrWQ

    Actually even with G8F/M, there's very subtle change when toggling Snapping or FK/IK, easy to overlook...

    @Padone

    Here's an example how I recproduce it from the rig > convert > posing > snapping problem
    blob:https://giphy.com/e5693e30-8451-44c7-9693-9b0a6aab7059

    (Please copy paste the urls including the blob word to see the gif)

    I use g9, MHX, no limit, no poles

    It seems up to certain point the bones will stop moving after awhile of snapping back and forth.
    It could be Padone can't reproduce the problem because there's certain situation, where the snapping wont show any problem.

    Nope, G9 works fine here, blender 4.0.2 mhx 1.7.4.0111, or please describe the exact steps to reproduce the issue as simple as possible.

    my steps:

    1. import G9, then convert to MHX without poles
    2. pose the hand with the IK control and keyframe
    3. snap FK to IK then IK to FK multiple times, works fine nothing moves

     

    update. It seems it's disabling limits with the MHX panel, while disabling in the global settings works fine. Reported to Thomas.

    I'm using blender 4.0.2
    MHX 1.7.4 (is it different from 1.7.4.0111?)
    The add on says the version is 1.7.4.
    I downloaded it from the repossitory.
    Which I think that should be the most updated commit.

    Here's the step by step How I did it.
    This time I use the leg.
    No need of a keyframe.

    I attached the video in above post of reproducing the issue you have in the same way. The issue really exists there. That was why Thomas added Pole Targets to assure perfect snapping I presume.

    Your latest version numbers are correct. But your link shows no GIF or file...

  • JamesJames Posts: 1,145

    Do you include the blob?
    Don't just click it.
    Need to be copy pasted.
    It's a strange kind of a link, but I dunno, that's how the host provide the link.

    The address is stated as invalid if including blob. NP~ anyway I experienced the issue on my side.

    OK, I've updated the link.
    The video is for Padone to see, the steps I took.

    Anw, I tested to disable location and rotaition limits from  global settings, but the FK IK snapping problem still persist.

    Why sometimes the body  mesh could become totally mesh up when I import a pose?

    The bones pose correctly, but not the body mesh.

    https://prnt.sc/9k4dnfrZa7FP

     

    I loaded a scene where there are 2 figures standing in the center of a room in neutral A pose.
    One figure always bending like that, everytime applied a pose, the other is not.

    It looks like the mesh is not normalized, easy import does it by default. For example if you enter edit mode and move the mesh away from the armature then you get those "rubber" effects because the pivots are misplaced.

    update. I tried to easy import multiple G8 G9 figures together and it works fine here. However, importing each figure alone is recommended, especially for complex figures.

    Hemm, I did use easy import.

    Why it still behaves like that?

    Currently I have to easy import one by one, to prevent that. Each character, and then the scene.

    Base figure ? or custom figure ?

  • JamesJames Posts: 1,145

    both custom figure.

  • crosswindcrosswind Posts: 9,548

    Rigging of both custom figures have been adjusted to shape in DS?

  • JamesJames Posts: 1,145

    It's a DAZ store figures.
    I supposed it's adjusted.
