How to limit which bones to be exported from DAZ in FBX?

I want to use cascadeur, but the free version limit only 120 joints when exporting from Cascadeur back to DAZ

I think many bones on the head unnecessary, cos cascadeur only use the neck and head bones.
Also fingers.

How to limit which bones to be exported from DAZ in FBX?

    No limitation can be set when exporting FBX from DS... you want to set limitations when exporting FBX from Cascadeur if it's really needed....

    However, if you use, for instance, G8 figure, don't worry about that 120 limitation because as default, only 94 joints (incl. root node) are needly to be exported as FBX animation by Cascadeur (incl. fingers' joints but there's no control of fingers in free version, so it even doesn't matter). G9 should be even less (I've not tried it yet...)

    really?
    G8 is not 170? That's what I read on another thread.

    I can't export any pose or animation from Cascadeur right now.
    It keeps throwing errors saying the limit of 120 joints and 300 frame for the free version.

    Since I don't use 300 frames, then it should be the joints.

    Well, once I had succesfully  exported the figure from Cascadeur back to DAZ. but now, it just throwing errors.

    Here're two ways you may try:

    1st way, before export to Daz FBX, delete unnecessary joints in Cascadeur, as per the screenshots 1 - 2.

    2nd way, before export to FBX in Daz, delete sub-nodes - Lower Jaw and Upper Face Rig as per screenshot 3, by using this free script - http://www.mikededes.com/delete-selected-bones/. Then import FBX to Cascadeur, Rig, animate and export to Daz FBX, then send back to Daz.

    Both these ways worked on my side, with Cascadeur Free version.

    I had no problem using a G8 in Cascadeur when I was on the free version. I suspect the problem is not the figure, but how you're exporting. Go to the Commands menu and choose "Export to Daz".

    @crosswind
    Do you ever cross a problem where the pectoral of the character always goes up, when sending back to daz?
    @gordig
    I use the "export daz"
    Maybe Cascadeur add a limit on the new version. currently it's 2023.2

    Yes, even with Pro version... You may either uncheck "Is exported" in Object properties panel - FBX export, for both pectorals, or when you apply pose preset in Daz, hold Ctrl to apply the preset and check "Obey Limits", or Zero poses of pectorals joints as you wish.

    The limit of exportation was newly added.... I also remembered there was no error message in older version when exporting to Daz FBX...

    @crosswind
    Do you know how to export a character with all the props, ex: shoes, hat to cascadeur?
    I always end up only with the shoes and hat, but the body mesh is missing.
    I tried various settings, but end up with the same result.

    DAZ video  about exporting a character with all the things is outdated.

    It seems that my sneakers causing the problem.
    If I put the sneakers on, using the settings above still causing the same problem.

    If I delete it, then it's okay.
    Other shoes, no problem.

    I'm not sure why the LJO sneakers do that.

    If the mentioned sneakers are from this product - https://www.daz3d.com/dforce-hnc-leather-jacket-outfit-for-genesis-8-males I've found no issue there.

    Yes. That shoes.
    This problem also appears on grafts.
    (Why... this is happening to meee T_T)

     

    And I've found another problem.
    One of my character doesn't show upper and lower face rig bones group on the DAZ scene Tab.
    But when in Cascadeur it shows.
    Is there a way to hide/unhide bones from the scene tab in DAZ.
    So I can delete them.

    If those shoes contain a geograft that hides the feet, that might account for it as geografts tend to screw up FBX exports. I should add that I always export my characters to Cascadeur naked, which keeps the number of joints down.

    First, don't export with geo-graft, which is not necessary for animating your figure with Cascadeur. LJO Sneakers do have auto-hide grafts but it do not impact export bones for animation in Cascadeur.

    For hidden rig bones, tick Show Hidden Nodes as below.

    Yes... but that'll be a bit cumbersome by writing a Script. Actually only G8F Dev Load has such an "issue", you may simply follow the below steps to "make a modification" in batch ~

    1. Open "Genesis 8 Female Dev Load.duf" with Notepad++;
    2. Replace

    ,				"extra" : [					{						"type" : "studio_node_channels",						"hidden" : true					}				]

    with Null (empty..). Save and reload "Genesis 8 Female Dev Load.duf".

    3. If there's the same issue in other Scene File(s) you ever saved with the original version of Dev Load, open the Scene File(s) and do the same as above, if you'd like to...

    I made a script to get under 120 bones on g9 by removing the facial bones and doing a silent export. its in freebies incase the above didnt help^ (didnt work for me)

    https://www.daz3d.com/forums/discussion/668346/script-to-lower-figure-bones-count-and-export-as-fbx-to-cascadeur#latest

  • crosswindcrosswind Posts: 6,987

    Thanks ~ but MikeD's script always works well... expand all from Head node first and all facial sub-nodes need to be selected before deletion...

  • torn1942torn1942 Posts: 2

    True! though I needed to use that fuctionality in my own script so I had to make my own multiple-bone delete script cool

    https://github.com/ibrahim-humadi/Daz-Misc-Scripts/blob/main/deleteBones.dsa

    Select as many bones as you want and run script^
    Mine's not encrypted too so feel free to use in your automations! :)
