? ... never heard of that happening before.

Oh ;7; The only thing visible are some bones at the center part...

You must have clicked on something wrong - adding bones doesn't make materials disappear.

Uuuu ;u; I just moved the bones and changed the child/parent bones for them and such...

Sometimes when you mess up the bone hierarchy, the model displays in a really odd way. It's happened to me when I messed up. Might want to check your bone hierarchy (and that can be a real pain).

Ahhhh ;7; I tried to make it seem almost exactly like what's in the picture, with just a little bit of editing due to model height...

You do have a back up of the model you're working on right? Best thing to do is redo from start. Just add the groove bone first and see if that works before messing with the model's height (as that can really mess things up).

actually what do you mean by edit the upper and lower body

If the center bone was originally the parent bone, then when you add a groove bone, that becomes their parent instead. In turn the groove bone has the center bone as its parent so the hierarchy is maintained.

Well...you just saved one of my models from looking like a total doofus in a motion data. Thanks!

How do you attach a bone in the first place? I'm using PMX editor so mine looks a little bit different (I also cannot read Japanese very well) Along with not being able to read Japanese, I am not that great at PMD so...please help me a little bit more. Your tutorial is great by the way
👍: 0 ⏩: 1
You attach a bone by telling the PMD/PMX editor to which bones it is supplicant to (ie. which bone is it's parent and if relevant, it's immediate child). There are fields for the parent/child entries. Not something that's easy to explain in words I'm afraid.

That to me, actually makes perfect sense! Thank you very much.

What's the difference between the new and old placement?
👍: 0 ⏩: 1
What the groove bone really is, is a center bone with reversed orientation. If it is used in a motion it will add slightly more bounce to the movements. But due to the lack of proper documentation a lot of people, me included and a few Japanese modelers, made the wrong assumptions about it. Once you think it through, it makes logical sense which is what I did and, hence, why the correction was necessary.
Impact is minimal as no harm (or real benefits) will be done if the model had an incorrect placement of this bone, especially since most motions still don't use this bone. This is probably because of the confusion over the placement of the bone due to a lack of proper documentation.

I see
Thank you for explaining. Whenever I need to make/edit a model and add a groove bone I always go to your tutorial because it is so clear and simple :> I'm glad it won't do anything that bad since I've added it on a couple models so far!

I've been slowly correcting the placement on my models.

I suppose I will too then XD

Dear Trackdancer, could you please make a tutorial how to add rotating bones to the arms? I can't find one anywhere

Adding a twist bone is situational. What work is needed to make it work on different models will vary from model to model.
👍: 0 ⏩: 1
So basically - it won't work for some models?
👍: 0 ⏩: 1
It will work on most humanoid models, just that models are different and there's no generic way to do this. Its also quite fiddly.

I was just hoping that I will be able to make rotating bones for Dreamy Theater models since some motions require having them...
But I see it's much harder than I expected. Nevertheless, thank you for response Trackdancer

It isn't hard, just hard to explain.

Like everything in PMD Editor

Could you tell me how to use the plug in or make another tut for PMX
This is strictly for PMD and I no longer use pmde only pmxe
👍: 0 ⏩: 1
[1] Adding a groove bone manually to a PMX model uses exactly the same procedure as with a PMD model.
[2] There's already a tutorial on how to use the plug-in. But basically, it's easier to use the plugin but its hard to explain w.o pictures (I'm assuming you don't read Japanese either).
Try and find that plugin tutorial, it might be listed on Citrus-Smoothie.

I actully just found a semi bone plugin that does more then just groove bone. But still thanks for replying ^_^
👍: 0 ⏩: 1
This just helped me so much! Thank you
👍: 0 ⏩: 1
YW - you could also use the plug-in. That does all the work automatically.

Cool, thanks for the tip
