avatar-rigging

[sage patio]

you mean hitboxes?

if so, that's not something you really do

[tender summit]

i forget the name , the capsule restraints for dymamic bones and cloth physics

[sage patio]

colliders?

dynamic bone colliders are their own thing, cloth physics use capsule colliders with Is Trigger enabled

[tender summit]

oh i thought capsule colliders worked for both

is there any way faster way to make them rather than going manually?

[graceful escarp]

for cloth you can also use two sphere colliders to form one collider for it

[astral warren]

Rigging is super complex and not really meant to be an automated process the fact that one exists at all is feat of its own

[elfin nexus]

is there any reason why mine (and nearly everyone elses that i've seen) avatars hardly move their shoulder bones?

when we raise our arms up, our shoulders only move a little bit when they should be raising up way more than that

i notice it all the time but then when we take our avatar to a dancing map the avatars arms and shoulders move and look much much better

is there something we're missing or is this just the way things are?

[hearty thunder]

Has to do with how the IK solution is set up in VRChat. Though, I think it has more to do with the VRIK VRChat is using, more so than anything VRChat are conscientiously doing.
Comes down to a lack of tracking points. You can IK a 3 point system (hip-knee-ankle and foot / shoulder-elbow-wrist and hand) fairly ok, but have a 4 point system (shoulder blade-shoulder-elbow-wrist and hand) and suddenly it becomes way harder to know what to do with all the joints. (This is why people clamour for elbow and knee tracking.)
Any IK where you strictly only have a start and end point is largely down to artistically tuning in and guessing where the joints should be based on the start and end points. Which with how the VRIK solution decided to handle shoulders, it basically largely mutes them as you noted.
Also, shoulders are pretty hard to weight paint well, and I'd imagine on most avatars if you went and moved the shoulders a bunch it wouldn't look great.

[formal hare]

2 Things:

1. I noticed my avatar is not moving the neck bone properly, as if i rotate my head ingame only the head bone will rotate, but the neck will stay in-place; and it will only move when the chest moves. It moves/is weighted fine in blender & unity, but having it animate in them causes the same issue; how do I fix this?
2. My avatars have bent knees when in fullbody, i can fix this if i calibrate then physically hold my tracker up higher (by a good few inches) but obviously thats not a real sollution; how should I go about fixing that as it seems like a rigging issue?

[elfin nexus]

thanks for the response i guess that makes sense yeah. Thankfully the weight painting for my shoulders in blender is quite nice, just never reflected in game, thank you!

[astral warren]

Also real life shoulder bones don’t move very much. They are surprisingly inflexible compared to the upper arm. Most rotation comes from the ball and socket joint at the end of your shoulder bone rather the clavicle

[cedar vapor]

Hello, I’ve created my own avatar but when I upload it to Vrchat it’s invincible. I can’t figure out what I’ve done wrong, do you guys know what might be the problem?

[astral warren]

Could be a bunch of things. First, did you place the avatar descriptor on the root of the game object? If it is placed on a different object or placed inside it on its skeleton everything else isn’t going to get uploaded

[cedar vapor]

That might be it cause when I was the upload screen there were no photo of the avatar

[astral warren]

Did you have any warnings before upload

[cedar vapor]

Ok I’m gonna start from scratch

Is it best to use sdk3 or 2?

[modern lantern]

2 is simple, while 3 allows lot more customization. If you start with 2, it will be harder to learn 3. So for long term benefit, start learning 3.

[cedar vapor]

I got it to work using the SDK3

But my hands and gestures are way of and lipsyncing is not that good

Can all that be changed in unity?

[modern lantern]

Depends on how "way off" and "not that good" is. Could you describe the detail? Preferably via image or video

[cedar vapor]

I will send an image later but basically it’s the fingers are not moving the direction palm if that makes, it does not look natural at all

[honest ice]

HOW DO I MAKE this rig work

i cant figure it out at all

plz help

[cedar vapor]

have you added avatar descriptor?

[rose wadi]

Hello! if i were to give to someone knowledgeful on rigging/weight painting my blender model, could i ask what's wrong with it? it 'works' currently when in VRchat, but looking at my arms in first person it's like the arms are pulled way back compared to the skeleton/where my arms are IRL (so i almost can't see my arms unless i look down), i'd bassically want my models skeleton to act like any basic nicely working vrchat avatars

[storm reef]

Can i pick some genuises brains? I'm created a few avatars now, number 1 was a write off with FBT, second one somehow works flawlesslely, but the last two i created are getting mild side hip tilt. I've got them both refined so it ever so slight, probably to a point that only i would notice it, but the fact is it's still there. All bone roll set to 0, and aside from flipping the hips i've tried nearly everything, changing origins, moving bones around, and yes i've watched Kung's guide multiple times. I'm trying to avoid any "rig hacks" as SDK3 documention claims those will become broken in the future. Here's a screenshot of the latest rig, please let me know if you can pick out where i'm going wrong. Thanks for you time.

(mesh hidden for clarity)

[unreal shoal]

Does anyone have an idea why this won't bend in Unity? the dynamic bone shows.. .but it moves while the poster sits still

[glacial minnow]

I’m sorry but I do not

[unreal shoal]

i weighted it to the bones

but the bones move without taking the mesh

[vivid carbon]

how many tri's are there in that square, if it is a single quad then that would probably explain it

[unreal shoal]

nah.

it bends great with the bones in blender, but in unity it's like the bones aren't conencted

[sage patio]

@unreal shoal make sure there is an armature modifier on the mesh

[slate sky]

@remote jay

[crude lake]

I have a GLTF model that I would like to rig for ingame use. Can anyone help me with that?

[pure dome]

i've got a friend whose avatar has four tentacles instead of legs and we're trying to figure out how we should rig it for vrchat, does anyone have any ideas? https://twitter.com/octakopie/status/1376415679218388993/photo/1

[crisp tendon]

probably won't walk, so dummy humanoid armature with animated tentacle walk cycle

or dynamic bone

[sage patio]

@pure dome either dynamic bones or FinalIK

or like ruuubick said, you could just animate it manually and use that for walking animations

[pure dome]

when you say dynamic bones do you mean basically just having the model slide along with non-weight painted legs and then the tentacles just sorta wiggle behind the model or is there something else you can do with them?

as for the animation idea do you know of a guide on how to replace the vrchat walkcycle with a custom animation (if that's what you're referring to)? because that is an unfamiliar world to me

[crisp tendon]

plenty on youtube afaik

[fervent hornet]

Is it really a good tentacle monster if each tentacle doesnt use CCDIK to ground itself 😔

[hearty thunder]

As the others have said, either custom locomotion animations and just live with no real full body capability below the waist, or you set up a combo FinalIK and Dynamic Bone thing where the wearers feet kinda puppet the tentacles around, with some flopping around so they don't look completely stiff.

[pure dome]

they do not have a vr setup so full body tracking wont be needed

[hearty thunder]

Any aspirations for such in the future? Better to future proof than to have to gut and redo half the setup to make things work.
Unless it's a absolute hard no for ever getting into VR, there seems to be a recognisable pattern for people who play,
"Oh man it be so much cooler/better if I was IN this with you guys!"
"Man, my PC sucks. Looks like it's upgrade time! (Literally just for VRChat.)"
"This fun and all, but I hate how I can't move my lower body around, looks like I'm getting Vive trackers now!"
Every time, life situation depending of course.

[winter axle]

my bones for my model here should be fine right?

[hearty thunder]

Don't want the hip bone under the leg hip bones.

[winter axle]

so something like this?

[hearty thunder]

Maybe not that extreme, but yes.

[winter axle]

so i want the dotted lines level ?

[crisp tendon]

Nah rig is good

But whatever bone is below the hips you want to get rid of it

and shoulder bones be flat

well i guess it doesn't matter if they're not weight painted

[winter axle]

theres no bone below the hip bone. thats just the hip bone

should it not be like that?

[crisp tendon]

There's definitely a bone at 0,0,0 in a screenshot above

#avatar-rigging message

[fervent hornet]

dotted line shows child-parent

[winter axle]

oh the one at the feet. thats the base bone. i should delete that?

[fervent hornet]

Yeah you dont need it

[winter axle]

i thought with a name like Base Bone it was important

[crisp tendon]

[fervent hornet]

A root bone (or base bone) is useful in some applications, but for VRChat you dont need it

[winter axle]

ok. i didnt know that

so this may sound dumb but how do i attact the armature to my model? at the moment my model is just kinda ontop of the armature.

[fervent hornet]

You need to weight paint it, the mesh should be a child of the armature and have a modifier that applies weight

[winter axle]

i still cant connect my armature to my model.

what exactly am i doing wrong?

i have the mesh parented to the armature but i cant select any bones when i try to weight paint

[sage patio]

@winter axle bones don't just magically make the model move

you need to tell vertices which bonee they should follow by assigning them to vertex groups with the same names as the bones, typically done through weight painting

[kind mortar]

You don't select bones, you select this

[sage patio]

if you want to select bones directly rather than the vertex groups in weight painting mode, them make sure to select the armature and shift click the body before you switch to weight painting mode

then Ctrl + click a bone to select it

that way, you can also hit R to rotate the bone to test your weight painting

you should also enable X mirror and Auto normalize in the top right

AN is under Options

[kind mortar]

also make sure the x y and x are not highlighted when you weight paint x.x Made that mistake more then I can count

[sage patio]

@kind mortar X mirror is very useful

[kind mortar]

Not when you're painting boobies 😅

[sage patio]

it's still useful

need to make sure your mesh is symmetrical

you can also use Weight paint tools (add-on) to mirror-project weights on non symmetrical meshes

[crisp tendon]

Your boobies aren't symmetrical ? yikes

[sage patio]

lmao

[kind mortar]

I like the jiggle to be set to each individual 😄

[sage patio]

@kind mortar ...mirror does that

[crisp tendon]

That's what symmetry is lol

[sage patio]

if your vertex groups follow a proper convention, like Boob_R and Boob_L, then painting for one willl mirror for the other

you can also use a . rather than a _

[kind mortar]

The way my bones are set, they are painted separately 😄

It works perfectly for me

[winter axle]

my armature doesnt have a selection for Vertex groups

[sage patio]

@winter axle when parenting the mesh to the armature in object mode using CTRL + P, you can choose a few options

one of those is Using automatic Weights

which will try to do the weights automatically based on the proximity of the bones

but if you want to do it yourself, you can use With Empty Groups to create all of the group's for you, but with nothing assigned to them

[winter axle]

im still confused as to how i parent the mesh to the armature.

also does it make a huge diffrence when the head of my model and the body are seprate?

[kind mortar]

Click the mesh first, then hold shift and click the armature and Ctrl P

You can have tons of separate meshes as long as they are connected to the bones

[winter axle]

whats it mean when i get an error saying Bone Heat weighting: Failed to find solution for one or more bones

i got the head to work with the armature. but the body is having issues

whats bone heat?

[winter axle]

whats going on here?

how do i fix Bone Heat?

[atomic harness]

I Got this model but when i export it the camera is at like knee height.
any idea what could be wrong?

there are like alot of bones

[north knoll]

If I've added bones to a model in blender, and weight painted them such that things move correctly in blender when I move the bone, but in unity moving the bone does nothing, what's most likely the issue? I've been googling for a while and not figured it out.

[sage patio]

@atomic harness the models origin should be at the feet

right now it's at the crotch, and your model is half way through the floor

[sleek radish]

I know that VRChat uses very specific proportions to do a lot of the full body tracking. Does anyone know if there is a "Optimal" skeleton/armature with those proportions and bone positions baked in?

Something I can use to at least sanity check my own model's rig against.

(especially for thumbs, dear god)

[sage patio]

proportions should be following your own body's proportions for the best results

this is the "standard" rig

some of these bones are not required, such as the toes, and the pinky and ring fingers

[sleek radish]

Noted.

[sage patio]

you can also optionally have an UpperChest bone

[sleek radish]

That doesn't break anything?

[sage patio]

I thought it did too, but apparently it doesn't, according to one source

[sleek radish]

Hm

Interesting. I'll keep that in mind.

[sage patio]

what does your current rig look like?

[sleek radish]

Unity doesn't track bone roll or head/tail, correct?

[sage patio]

the head of the bone determines where the bone's pivot is

there is no bone length information preserved

[sleek radish]

Currently just plotting out a new avii, and it was a question that always tickled my braincase.

[sage patio]

so if you need that, add an extra bone at the end of the chain

call it like _end or something

[sleek radish]

I'm dreading adding certain stuff like twist bones, since I'm not quite up to speed on how the rig functions, compared to blender.

[sage patio]

I've not messed with twist bones but they can definitely help

not too hard to set up either

then again that won't really have an affect on the proportions

[sleek radish]

Yeah, I know they'll be needed for this guy. I'm just plotting out what I need to know and targeting each in order, as it were.

I think currently the rig rotates the forearm wholly with the wrist.

[sage patio]

it mostly does yes

[sleek radish]

(the standard 3.0 humanoid)

[sage patio]

the alternative would be to have the wrist become extremely over twisted

[sleek radish]

If so, that will effect my twist bone placement and painting

[sage patio]

hm

yea that's an interesting point

[sleek radish]

Gonna be fun, especially since the body is cyberntic, so I get to do both hard surface and soft surface painting

[sage patio]

if the forearm is twisting to compensate for the wrist twisting, wouldn't adding a twist bone for the lower part of the lower arm not do much

[sleek radish]

Yeah

[sage patio]

since the problematic area isn't really the wrist anymore, but the upper lowerarm?

due to the IK?

[sleek radish]

You'd have to weight the upper part of the forearm to a twist bone that's rotation constrained to the forearm, but only on two axises

Sort of a second forearm.

Fun stuff.

[sage patio]

yea

[sleek radish]

That's why Im looking into it before doing all my rigging. If I can know what I'm going to be aiming at, easier to hit the target

[sage patio]

or putting a negative value for the rotation constraint

[sleek radish]

Especially if I do some of the muscle bones I plan to have. Damn my obsession with anatomy.

8 bones just to ensure the pecs don't act oddly. 😒

I'm going to have to make a script to apply all these constraints based on name. I'm not doing this all manually, lmao.

[sage patio]

kek

[sleek radish]

Should be easy, as long as I name each bone correctly.
Maybe "XY.Elbow" where XY= the axises to be constrained, and "Elbow" = the parent bone to constrain to.

Then just a script to parse the bone name and apply the appropriate constraint.

I'm honestly surprised this isn't already a thing, but maybe it is and I haven't seen it.

[tawdry dragon]

Hello guys! So my rig is working with the mesh. Lip Sync in Unity is working too. But now i had to separate the head, jacket etc, in edit mode in blender from the mesh, so i could put the texture on correctly. Because the first version was just like one material and effected everything. After finishing shading and exporting, my lip sync is not working anymore in Unity

[kindred pollen]

should preferably keep one material and one mesh for everything, multiple meshes/materials is v unoptimized o:
also doing that might have destroyed the blendshapes, so you'd maybe have to recreate them?

[sage patio]

in the lipsync section of the descriptor, you need to specify which mesh to use for the face

also you shouldn't really need to separate the meshes to texture them

you can just add materials and assign parts of the mesh to them

[tawdry dragon]

I tried your tips, but they were not working. Still thank you for your help 🙌 What i did now was after shading/texture the meshes that i separated. I just merged all meshes and exported it. In Unity i created for every material a preset. AND EVERYTHING WORKS NOW 🙌 💯 You can't imagine guys how happy i am right now!!! 😊 I was working on it for like 7+ hours. I hope this helps someone too. Can't wait to see you guys trying the new avatar.

Thank you, guys!!

[hot pumice]

Has a solution ever been found to this issue? I have been attempting to fix this for a long period of time now, but have been unsuccessful.

[turbid spear]

Can you post your armature in blender from the front and from the side

[fading verge]

thank you for these tips. are these standing animations in the sdk somewhere (SDK3)?

[vivid carbon]

The proxy anims are, not the full ones

proxy_stand_still, proxy_stand_still2, proxy_stand_still3

[fading verge]

Ooo that's helpful

okay thanks

[fierce grail]

Use orthographic view (Numpad 5 to toggle it) for screenshots and those photos perfectly from the front and side (Numpad 1 & 3 respectively).

[hot pumice]

I'll keep that in mind, thank you

[ivory grove]

I'm weight painting a skirt, so I added some bones as children of the left and right legs along with their vertex groups, tweaked it and tested it in pose mode and everything looks and moves fine in blender, but when I import the fbx into unity one of the sides looks all "scrunched"

I literally did the same process for both sides, yet only one of them is causing this issue, why could it be?

[turbid spear]

Yeah, post some orthographic screenshots, it's easier to see if something's not aligned well. I think this is usually a hip issue but I'm not sure

[soft star]

so for some unknow reason unity added my rig as a bone on my finger ( between left index 2 and left index 3 ) and it won't let me remove it or change it

and it for some reason is overriding the finger bone

whats more confusing is that no such rig bone exist in the blender file.

[soft star]

can i get any help with this issue or am i gonna have to start from scratch again?

[turbid spear]

Uh, what?

[turbid spear]

Personally, not sure, but I've heard about this issue before so you should try and just match a working armature

Try matching the one in the channel pins

[hot pumice]

I'll see if I can make a second version and overwrite the bones after matching scale, maybe. I'll see what happens.

[soft star]

so after a re-import it seems the rig one isn't there anymore, (likely an error on unity's part) seriously how is this stuff not fixed.

[faint wadi]

That's a cool avatar 😮

[cinder sable]

I weight painted something to a rig that works in blender so it would move with dynamic bones in unity, but it doesnt move

what do I do

[wheat beacon]

Can someone help me with cloth?D: I did everything how it was supposed to but as soon as i am in game the mesh moves with my head..

[untold monolith]

show a picture of the mesh youre using in the avatar's hierarchy?

[wheat beacon]

unity?

[untold monolith]

yeah

[wheat beacon]

https://gyazo.com/216c1f51238f1ebe1e80e650ceaf1267

[untold monolith]

does the dress move with your body/hip/etc. when the cloth component isnt activated?

my suspicion is the dress isnt weighted to anything

[wheat beacon]

it is weight painted to the chest

[untold monolith]

so when the cloth component isnt activated when your chest moves, it will move?

[wheat beacon]

yes

https://gyazo.com/8bd485cf0805902215f180724f81e0c3

[untold monolith]

how does the...forget what the term is, those orbs you paint, how do those look

usually at least the topmost ones should be red

or 0 movement or w/e

[wheat beacon]

https://gyazo.com/c6bdc0572acfad1a082994b027b7626d

its not my first time doing cloth

i never had this issue before

[untold monolith]

wew thats a lot of verts
does it look fine in unity play mode?

[wheat beacon]

https://gyazo.com/cf62517c4b6540fdcb1f5c80a46b2520

yeah it does look fine in unity play mode

its like i always do cloth

but as soon as i am in game after 2 seconds it starts to follow my head movements

[untold monolith]

what does your armature's transform component look like?

[wheat beacon]

i even took all capsule colliders down to see if that was the issue, but it was the same

you mean this? https://gyazo.com/b4abba24a9173b8846886101c6a4e932

<.<

[untold monolith]

i know ive sometimes had weird issues with cloth when all of my object transforms weren't 0'ed out
does your skirt's transform look similar?

[wheat beacon]

https://gyazo.com/50d17db544e897add0e6580655cc2af9

[wheat beacon]

was it the same issues?xD

[untold monolith]

hm

different issue, they would spazz out and fly outwards

i would backup your fbx and unity savefile just to be on the safe side

but you could try selecting the dress in blender, hit f3 and search apply object transform, and that will probably bring it to the like
0 0 0
-89.98 0 0

the reason i say that is it might mess up the cloth component

so make sure you have a savefile with your old cloth component settings

in case that doesnt help and you need to revert

actually

hm

before you do the blender work, backup unity save and right click on the dress's transform component and try revert to prefab @wheat beacon

and see if it 0's that stuff out
in either case if neither of those addresses the issue then im at a loss, too

[wheat beacon]

tried all..q.q nope

nothing changes

[untold monolith]

huh, that's quite weird.... one last idea came to mind: are any of the bones the dress is weighted to constrained to something?
i have one cloth physics thing that moves with my head and the mesh its on is on a constrained object

[wheat beacon]

hmmm like for example hands? or?

because thedress is painted to the chest

[untold monolith]

i wouldnt expect it to have issues if none of the bones the dress is on are constrained
although if you do have constraints on the avatar you could try disabling them all temporarily as a test just to be on the safe side

[wheat beacon]

i dont have any though q.q

[untold monolith]

oh yeah then that obviously wouldnt be the issue. im outta ideas then

[wheat beacon]

this is the craziest thing ive had so far xD

[fading verge]

Why does Unity not automap my finger bones? I've sorted the Hierarchy, Vertex Groups, even renamed them all as attempts to figure it out but for some reason I have to place them manually in Unity

why is that?

[fervent hornet]

How are they positioned in world space?

[fading verge]

In Blender or Unity?

[fervent hornet]

Blender would be more clear to look at

[fading verge]

This is how they are positioned in blender

[fervent hornet]

Oh its a kon right?

[fading verge]

Yep

[fervent hornet]

Do you not actually have fingers?

[fading verge]

There are no fingers

[fervent hornet]

It might be struggling since they have no weights, regardless you dont need all those fingers if they do nothing

[fading verge]

But so that you don't crouch into the ground it has finger bones on it

[fervent hornet]

I think you need index, middle, and thumb

and only proximal

So even if you need to manually assign them, you only need to assign 3 instead of 15

The sdk will tell you what fingers you need if you try to upload without em

[fading verge]

Hmm alright I'll do that instead then qwq

[fervent hornet]

You can either just ignore the other bones when assigning manually or better yet delete the bones in blender

[fading verge]

True that

Thank you

[fervent hornet]

No problem gl

[fierce grail]

SDK3 avatars work completely fine in FBT if you don't have any finger bones at all, but in case of SDK2 it is as Scionzenos wrote.

[fervent hornet]

Yeah havent done a fingerless avatar since half life alyx came out and I got index controllers so Im going off old info 👍

[willow seal]

I have a problem

On my model, I can't move the mesh in blender, when I try in pose mode, it only moves the bones

[kind mortar]

Seems like your mesh might not be parented to the bones

[sage patio]

that's only part of the story, there are 3 different things that need to be correct

1: mesh needs to be parented to armature
2: mesh needs unapplied armature modifier with correct armature selected
3: mesh needs to be weight painted

[winter axle]

is the last tip of the fingers important. if not im thinking about getting rid of them on my model im making. can the model work with just those two main finger bones. or do i need those other bones at the very end of the fingers?

[fair plank]

Hey, when merging armatures like clothing and hair etc, should you merge them to the armature with the head or body?

Guess my friend'll just find out

[mild stratus]

You should have them, but they don't need to be weighted. You might be fine with two, but idk how the SDK will act.

[crimson girder]

is anyone willing to add different expressions to my rocket raccoon avatar a friend gave to me

[fleet lintel]

How do you make your rig have rotation limits/constraints once in Unity for VrChat?
I don't want the shoulders to rotate on their axies

[sage patio]

@fair plank there should only be one armature, I think you're getting confused with meshes

[cinder sable]

hey what do I rename the bones to on the body

I need to know

[fair plank]

Nope, I know there should only be one armature

[rose wadi]

heya! Anyone online and free? i wanna ask if someone free could see how i could improve my weight blending, it's already done but yeah in vrchat it's not perfect at all (the bones are setup right in unity) , but ingame i have a lot less good control of the arms than other base models i can choose online

i'd send you my model and such, or show you in a screenshare, see what's wrong with it

I doubt sending a lot of screenshot here would do good haha, especially since each bone has it's own part of the model

[peak rune]

am im trying to rig some hands from a mmd and its a nightmare

[vague laurel]

Did you know if you ever finished this??

Sorry for ping

[rose wadi]

here's the problem i'm talking about

ingame/invr, my arms always feel like i'm not controlling them right

(this is in the muscle pose so i can get a look at it)

[undone vale]

can anybody dm or just help me with my avatar animator problem?

[mighty pebble]

Have you tried watching this video? He goes into great depth with weight painting and modifying existing weight painting. As well as even as deep as studying human anatomy to determine where the weight should be. And fun shortcuts as well.

https://www.youtube.com/watch?v=2sfTEBAl8sA

It's a long video but it will save you probably 5x the amount of time in the future if not more. Armatures and weight painting isn't something you learn super quickly anyway

[rose wadi]

Thank you! i'll study that video then

lowkey if i can't do it i'll probably pay someone for it but hey last resort lol

[wide frost]

I'm Trying to make a cartoony character, So I want a sudo rubber hose effect like old school cartoons, how would I rig / weight paint this to get that effect ya'll think?

[winter axle]

so im making a robot and im having abit of trouble with the joints can someone tell me why my joints are making my model "squish" in onto itself?

alot of the joints are my model are ball joints and im having diffculty getting to where the model saves as it is. its made of metal. so it shouldnt stretch of squish but it is. can anyone tell me whats happening?

[crisp tendon]

It needs to be weight painted to 1 with no gradient and not affecting other parts of the mesh

[winter axle]

i used Automatic weight painting. is that not good enough for what im trying to achieve?

[sage patio]

no, absolutely not lol

doing so will still have smooth weight gradients between joints

you don't want any kind of smooth gradients

parts need to be weighed to one bone and one bone only

[merry valley]

Cleaned up some things and broke another. Almost feels like its actually dynamic bones effecting the head's mesh. Near the cheek bone area you can see clipping.

[merry valley]

Not dynamic bones since trying to excluding it. (The mask)

[winter axle]

Thanks Sacred once again. You have all the answers to my never ending animation trouble.

[sage patio]

😄

[round falcon]

Man.. I can never do simple things...

How do I add clothes to an avatar in blender that has pre-done armature / shape keys?

Merging armatures in object mode makes a clusterf*k of bones

[zinc fulcrum]

how do i make a wheelchair avatar in wich the arms move but the legs dont?

[sage patio]

@round falcon there are many ways, are those clothes specifically made for the model you are using?

also, you don't want to just join the armatures in object

you want to use the Custom model creation section in CATS

1 - import the outfit into the same project as your model

2 - under "Custom model creation" in CATS, have "Merge all bones" enabled, Apply transforms disabled, Join Meshes disabled, and Remove Zero Weight Bones enabled

3 - with the "Base" armature being your main model's armature and the "To merge" armature being the outfit's armature, click "Merge armatures".

4 - to test if it worked, click on the armature and switch to Pose mode (shortcut: ctrl + tab). click on a bone and move it using the rotate tool (or R) and see if it moves correctly.

5 - if everything is good, export the model, preferably using CATS.

[brisk terrace]

I need help with a weird behavior. In blender there is no issue with moveing the neck. But in unity , the face and part of the head don't follow when i move the neck.

[crisp tendon]

Where is the eye patch part in blender ?

[round falcon]

nice thanks

I don't use cats. But that was enough to get me to where I needed to go.

Click mesh, then click armature. Right click > parent > armature deform

[brisk terrace]

Eye patch is a separate object added in unity

[rustic needle]

anyone know the fix for this?

[sage patio]

open up your model in blender

[rustic needle]

now what?

[sage patio]

send a screenshot of what it looks like

[sage patio]

I think the origin is below the floor lol

do shift + C to center the 3d cursor

[rustic needle]

got it

[sage patio]

click on your model, do CTRL + A > All transforms

do this for both the mesh then the armature

then right click the armature and do Set origin > Origin to 3d cursor

you should then see a small yellow sphere where the 3d cursor is

that's the origin point

[rustic needle]

alright

[sage patio]

send a screenshot after doing that so i can confirm that you did it correctly

[rustic needle]

do i click on the model in object or edit mode

[sage patio]

object

[rustic needle]

k

the option for set origin does not show up for the armature only the mesh

[sage patio]

you sure?

[rustic needle]

yea

thats after i do all transforms

[sage patio]

in the top left of unity, do you see an "Object" tab?

[rustic needle]

I see GameObject

[sage patio]

uh

[sage patio]

wait

shit i meant blender lol

[rustic needle]

oh

yea i see it

[sage patio]

do you see Set origin there or is it the same thing

[rustic needle]

i see the set origin there

[sage patio]

aight

[rustic needle]

i think that solves that issue, another problem i have is that when i tested the PC version of the avatar it would like crouch or go prone

[sage patio]

that is probably the same issue

[rustic needle]

the same issue with the origin point wasnt in the PC version tho so thats why im a bit confused

[near grove]

is there an easy way to put a bone between my avitar's sholders and head that doesnt affect anything?

[sage patio]

@near grove what for?

[near grove]

Because the model I'm importing had no neck

And humanoid rig need neck

Else he goes tpose mode

[sage patio]

then yea you need to add a neck bone

you can split the head bone in 2

right click in edit mode > subdivide

then maybe make the neck one smaller

just need to check the weights afterwards

[near grove]

Can't you just add a null bone?

Aka a bone that doesn't effect the mesh

[sage patio]

a bone is a bone

whether you have vertices weighed to it or not

don't forget that the bone hierarchy important too

[near grove]

So a bone with no weights is easy to do?

[sage patio]

yea, you can add that in edit mode in many ways

[uneven needle]

I'm having trouble with FBT on this avatar I'm working on

normal tracking is fine

but the moment FBT is enabled it goes:

like a crab

any ideas as to what the problem could be?

[sage patio]

@uneven needle can you show us your rig in blender

[sage patio]

if you have any client mods, remove them

rig looks fine

[uneven needle]

none at all

...actually hold on

this isn't me testing it it's someone else, lemme ask

[sage patio]

it also seems like the hip tracker is flying off

ask them where they have the tracker dongles

or better yet

ask them to talk here

[uneven needle]

will do

apparently no mods

he wears it on the right side of his hip, and has 2.0 trackers

although FBT works on other avatars for him so I'm not sure if its the trackers' problem

[topaz surge]

im here

sup Sayuyu

[uneven needle]

this is my FBT guy

[topaz surge]

anyway to answer what ya put I have my dongles spaced apart and I dont lose tracking unless say my bed hides the ones I strap to my ankles.

my left foot seemed bounded to my chest and that was the only way I could move up. Tho to Sayuyu I was unable to be seen to them

[sage patio]

@uneven needle I meant the dongles. not the trackers

woop didn't read last message

[uneven needle]

I found a problem with the chest bone in the rig

it got unmapped at some point

[sage patio]

ah, fun

[uneven needle]

so i fixed that and i'm uploading a test

thing is, when i was testing it with just headset + controllers there wasn't any issues

and you'd expect that not having the chest bound at that point would cause trouble, but who knows...

[uneven needle]

yup that fixed it!

@sage patio thanks for helping

[misty rivet]

Hey not sure if I’m asking this in the right channel but does anyone know of any good YouTube videos or tutorials on how to put a avatar base and head together in blender? I have both but I’m unsure of how to correctly make them connect and fit together to make a complete head and body without leaving holes around the neck and back of head area.

[round falcon]

I cannot, for the life of me, get Voxian's rave pants to rig in blender. It's beyond frustrating. Nothing in it behaves as expected

[sage patio]

@round falcon go to the modifiers tab and make sure there is an Armature modifier present, and that Object is set to your main armature

[wild sundial]

Can someone help me with my arms twisting? It seems that in full body when I extend my arms in a t pose while looking at myself in a mirror they look just fine, but when I look at whatever arm is extended, they twist up a little bit and it seems the full extension length is shortened.

It doesn't twist in non full body mode.

I did already follow Kung's most recent limb twist fix but it's still twisting a little bit.

[round falcon]

oh nice perfect thanx

So... Pretty much re-rigging the thing from scratch.

For weight painting: Is there a way of increasing the contrast between colors, or otherwise showing ambiguously low values as something more easily visible?

[sage patio]

sure, you can either switch rendering modes, or switch it to Solid and clicking the black arrow to the right to tweak it

you can also go into the preferences and change what colors are used

[round falcon]

Having some crunching on the belt, and some sections with flipped normals when imported to unity. Goes away if I remove the associated vertex groups. Looks fine in blender though

Has me scratching my head a bit

[sage patio]

is it rigged?

if so, click on the fbx, go to the Rig tab in the inspector, and click configure

at the bottom, click Pose, then Reset

[round falcon]

noted no change

[sage patio]

@round falcon what if you drag the FBX into the scene again

[round falcon]

Nice that was the magic trick that worked. Thanks!

[sage patio]

@round falcon for future reference, if you change the pose of the model in the rig config, it won't show on the model in the scene. to fix that, you can reset the pose using Pumkin's

[shadow fern]

Does anyone know if there's a way to update an existing avatar's armature with additional bones without having to redo the whole avatar? Currently it causes the mesh to disappear and the only way I know to fix it is to drag in the new model and re-do everything

[wild sundial]

https://m.youtube.com/watch?v=2sfTEBAl8sA&t=

At 19:55 or so he re-imports a new model to unity. Follow that.

[shadow fern]

Don't think is gonna work for me. They're merely adjusting bones; I'm adding bones.

[sage patio]

@shadow fern yes, you can just override the FBX

make sure to always export using CATS, not using blenders default exporter

[shadow fern]

I am not using CATS

[sage patio]

why not?

[shadow fern]

Does nothing for me.

[sage patio]

CATS is a toolbox containing many useful tools. you don't need to use all of them

in this case, the export button in CATS is a shortcut

so you don't need to change a bunch of export settings yourself

[shadow fern]

I've already been exporting my stuff without CATS for years so I have no need for it.

[sage patio]

notably Leaf bones, FBX scaling, and enabling the meshes in the scene

if you reimport a model in unity and it breaks, just drag the FBX into the scene again and use Pumkin's to copy all components over

[shadow fern]

Now that's useful. I didn't know Pumkin made a tool for that.

[sage patio]

it's part of the Pumkin's avatar tools thing that has existed for a while

you just scroll down to the Copy components section

[shadow fern]

Cool, thanks for pointing that out.

[fading verge]

im making a avatar

[jade bane]

Can someone point me in a direction for figuring out how to rig a skirt? I want to add it to my avi as a seperate object in unity preferably so I can have changable outfits

Or would it be a lot easier to just have a seperate avi for seperate outfits lmao

[sage patio]

you can do changeable outfits in blender...

you should be adding your clothing in blender

all you do to toggle it is disable/enable the mesh

https://www.youtube.com/watch?v=SimRLR_lRcA

[jade bane]

Thanks, I'll look at it another day 🙂

I gotta take frequent breaks from the unity/blender life or I stop making progress lol

[forest charm]

Anyone know how to stop the viewpoint drift when sitting down in fullbody

[sage patio]

are you using the old (legacy) calibration?

[forest charm]

no

[sage patio]

could try either tweaking your user real height setting and recalibrating

otherwise you might want to edit your model

either by using an Upperchest bone for better spine bending, or tweaking the proportions to match your real proportions

[forest charm]

I dont have an upper chest bones

[sage patio]

I know, but you can always edit the model lol

if you know how

[steel bolt]

Hey, is there a rig I can download anywhere with all the default animations I can slap onto an existing mesh?

[atomic harness]

how do i rig hands and head of a non humanoid character

character doesnt have legs so the animations are non issue

@steel bolt rigs and animations are 2 different things

what mesh you got

i can rig stuff

[steel bolt]

Wait so how exactly does parenting animations to an armature work?
All I know how to do are the shape keys but how do I get the walking animations and such on the mesh?

[atomic harness]

if the rig is humanoid. it can use the defaults vrc animations

[steel bolt]

Even with a custom rig?

[atomic harness]

if its a human yes

or human like

if its a centaur or flying robot no

[steel bolt]

yeah its human the face isn't

[atomic harness]

thats already rigged

[steel bolt]

Yeah

[atomic harness]

i need to go in a meeting soon but i maybe can call you lateR?

i can help importing it in unity

[steel bolt]

Sure dms are open im about to head to bed tho.

[atomic harness]

ok in unity click on your model

press rig

animation type humannoid

and there you have a configure button

i need to run now

but uhm you can probably fix your stuff there

you can send dm

[steel bolt]

Alright ill check it out thanks, I was confused I always thought there was a premade amature with the animations attached that you parent

So that actually cleared up a lot thank you ill look into it

[atomic harness]

are you working on it right now?

[buoyant badge]

hello! i want to make my eyes a little lower, aka i wanna change my blendshape, can i do that?

[crisp tendon]

on Basis yeah

[steel bolt]

Didn't see this till now, idk what time zone you're in but I prob wont be on until like 12 hours from now.
Thank you for the offer tho, ill dm u if im having issues when im back to working on it maybe our free time will line up

Thanks again

[atomic harness]

so can anyone explain me how to rig an avatar without legs as generic rig with only head and arms

do it for KVN

[fervent hornet]

If you have arms, why make it generic? Do you use VR at all?

[atomic harness]

yes i use vr

i itill want to be able to use arms

[fervent hornet]

You cant use generic then, to use VR it has to be humanoid

If you dont have the required bones for a humanoid model, just have them present but unweighted

For example, have a full humanoid armature, then around the shoulder area you mesh sits with the arms weights correctly. Youll have invisible legs underneath you but it will allow you to use humanoid and VR

[atomic harness]

i did have tried that before. but i thought it was not the proper solution.

it also said you can make a custom rig. but it was more advanced

[fervent hornet]

It's as proper as you can get, you are making a humanoid that isnt humanoid 🤷‍♂️

[atomic harness]

and also poorly documented

[fervent hornet]

Generic is what you should use in a non-vr scenario, but in VRChat you need a humanoid if you want to use VR so you dont really have a choice

Generic is only good for desktop use in vrchat due to that

Even then youd have to manually animate everything about it, instead of using VRChats prebuilt locomotion

[atomic harness]

yeah i think there should be some option where you can set a bone to be IK tracked

[fervent hornet]

You can use Final IK to create your own inverse kinematics, however, you would still need a humanoid armature somewhere on your avatar to use your VR, making it kinda redundant in this case

[dusty sparrow]

What’s a good place to find someone to rig something? Mixamo is garbage and I’m willing to pay

[atomic harness]

humanoid?

[dusty sparrow]

Yes

[kindred pollen]

VRCTraders in the #community-servers-old, and/or https://ask.vrchat.com/c/commissions/40

[dusty sparrow]

To be exact it’s a halo character, but no rig

Alright

And rigging it is not something in my power I’m more just someone who fixes shoddy weight painting

[atomic harness]

oh right i can probably do that

[dusty sparrow]

Well, I’m not gonna get someone to do it now because we have a separate file with UV’s, but there’s also another one that’s very confusing but I have no pictures atm

I have like 4 that I want rigged honestly so I need to get everything separated

[fast berry]

Hey! What could be causing my avatar's hand in-game to split outwards like a starfish VS if i look at it in unity, it looks like..well like it should.
Is it a problem with how i set up my bones or could it be rooted in how the muscles are set up by unity automatically?
If i do any hand gestures in-game, the fingers seem to clip into a more proper angle. I've found that if i fiddle with the muscle angles, i can force my fingers to tighten up more but i cant for the life of me find a way to stop my avatar's hand from idling with fingers spread out sideways.

[round falcon]

2 blender questions:

1. Is there a keyboard shortcut for deleting blend keys? X, Delete do nothing. Bit of a pain to keep going back and forth to the minus button.

2. Any way of hiding / excluding muted shape keys from export? Yes I can delete them to remove from project.. But that would have some effects on future maintainability of the model

[sage patio]

@round falcon shape keys being on the model don't have a performance impact, apart from a slightly larger file size

it's only if you activate those shape keys that it has a performance impact

but to answer your questions, I do not know of a shortcut to remove shape keys. you can probably just make one though

right click on the Minus button

and for the 2nd question, maybe? not sure

[round falcon]

OH gotcha. So the goal isn't to yeet them. It's just to leave them set at zero. Ok, easy enough.

Minus button shortcut isn't working. But meh, sort of made myself a template to make stuff easier

[compact sage]

How do you rig a furry head?

[crisp tendon]

Same as any other head

[atomic harness]

need to be more specific

[compact sage]

I tried this, but thing went hay wire when I try to rig eyes and hair

[crisp tendon]

Head bone needs to be straight

hair should be fine

eye bone should be created in the middle of the eye sphere

[compact sage]

straight up?

[crisp tendon]

yep

[compact sage]

lemme check

[round falcon]

Known issue in blender where reverting a shape key applied to basis causes a python traceback error?

[compact sage]

Idk what the issue is?

hello?

[crisp tendon]

Your issue is the weight painting

So you need to weight paint your head mesh appropriately

[compact sage]

lemme tryyy

[compact sage]

gonna take a while but thanks :3

[round falcon]

So unity and blender are having a disagreement about object position.

It's a collar, with separate tag / ring / base mesh. Base collar is in correct position, as is D ring. Keyring is same offset from origin but in Z direction instead of Y. And tag is same offset from center but in -Z direction.

Tried setting origin to center of mass, but noted no change.

ehh?

[sage patio]

did you make sure to apply all transforms?

ctrl + A

[round falcon]

No change

[sage patio]

also, why are those separate meshes

they really should be one

[round falcon]

How the FBX is set up. Works fine if dragged and dropped into heirarchy in unity. But blender as an intermediate makes it angry

[sage patio]

you really should just join the meshes

and just have the whole thing just weighed to the neck bone

[round falcon]

But then the tag won't jingle jangle 😛

[sage patio]

then add extra bones for the other parts

collar weighed to neck, extra bone for both little chain segments (really no point in one for each), and another one for the tag

[round falcon]

Fair enough. Even w/ the meshes joined, it's still getting pissy in unity. I applied the transforms after joining and it's well... off kilter

[midnight snow]

can anyone rig a 3d model for me? its decently small so he wouldnt be to much of a hassle right? or im just underestimating it lol. i cant figure it out and dont have the time to do it

[sage patio]

it doesn't have an armature modifier on it

make sure there is one

and that Object is set to your armature

[silver pagoda]

yo so ik that this is a channel meant for rigging but does anyone know how to turn a blender animation into a .anim file? I heard that its easiest to put an animation onto an avatar if its a .anim file

[crisp tendon]

Bake action > export your fbx

[eager obsidian]

Hi, i was looking for someone to help me rig up a model i want for VRChat but i have 0 experience using Blender and Unity. If someone is willing to help that would be nice (I got the model and resources but i don't know how to do the bones etc...)

"MF DOOM" (https://skfb.ly/6SruZ) by Joppe Min is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/by/4.0/).

Feel free to dm me

or @eager obsidian

[crisp tendon]

Give Mixamo a try !

[eager obsidian]

I'll see what i can do 😅

[molten granite]

this correct

never used blender before

[fervent hornet]

Correct for what exactly

[molten granite]

for it to work

if i continue

like move

[fervent hornet]

For VR?

[molten granite]

yes

[fervent hornet]

No, it needs to be roughly humanoid, if anything you need legs

[molten granite]

what if it just crawls

like a snake

a floating head with paralized lowe side

[fervent hornet]

I mean sure, you still need legs if you want to use VR

[molten granite]

yeah

[fervent hornet]

Even if they arnt used

[molten granite]

ok

ty

[fervent hornet]

But you can always have a fake humanoid, and then connect your blender thing to it for more freedom

[molten granite]

do the legs have to be at the end

where the spine ends

[fervent hornet]

Nah, should be at the point where that chain goes from going down to going backwards

Hierarchy matters though, needs to go hips->spine->chest->neck->head

[molten granite]

hm

i just moved the entire thing

but a few parts didnt move

oop nvm found the problem

[rain cosmos]

Does anyone have the Blender Add-On for XPS to PMX?

[spice umbra]

I have an avatar I rigged and everything is working great! Walking, animations, all perfect. Standing is perfect 80% of the time. But the legs random contort and crumple up. And idea why?

[crisp tendon]

Make sure the leg bones aren't completely straight

[vestal ermine]

pog

[spice umbra]

In what way? You mean with knees bent? Because they are bent

[crisp tendon]

Can you post the armature front and side view ?

[final bronze]

Physics bones, where do I start?
The only thing I've found so far is a built-in script called VRC_Physics Root.
Does that have anything to do with Physics Bones?

Or.. have they not released yet?

[crisp tendon]

They have not released

[indigo path]

excited for that

[pure mulch]

not 100% sure if this is rigging chat discussion but how do I fix this

(something about crouching breaks if I don't have the menu open

for additional context it only does this if im not moving, the feet go back down otherwise

[plucky ledge]

Can I please have some help rigging this!.

I've tried 2 amateurs but it just won't attach in blender.
I even followed a tutorial but it didn't work. (Yes i was using the same blender at the time 2.9) can someone please help me on this

[pine raven]

Been trying to swap out this model's hand for a new one, and I think I've mostly got it, but the end of the sleeve refuses to move enough with the rest of it

[crisp tendon]

Weight paint it

[pine raven]

Been trying to do that, but I can't figure out how to select the bone it's weighted to

[crisp tendon]

You can select the vertex group in the list, it's easier

[sage patio]

@pine raven either select the associated vertex group from the list, or

in object mode, select the armature first, shift click the mesh, and then switch to weight painting mode

then, you can Ctrl + click a bone to select it and the vertex group

[wild sundial]

I've been introduced to Pumkin's avatar tools (thanks Sacred) recently and I have to say it's a pretty darn cool tool.

Now the question: Is it still relevant to override the old .fbx by renaming the new one, dragging it in, and not having to deal with copying stuff over?

I'm cool with doing either method but I want to see if there are pros and cons.

[sage patio]

@wild sundial you should just override the FBX with the new version

so everything happens automatically and you don't need to copy anything over

your should add a bookmark in blender to the folder where the FBX is located in your unity project

so that you can export and override it directly

this will work as long as you never unpack the model

you should never have a reason to

[wild sundial]

Thanks sacred. The only reason I used pumpkins was because the regular fbx replacement didn’t work.

[jade bane]

God adding a skirt is hard..

[dusty sparrow]

Honestly it’s just the skirt physics that are a pain

[jade bane]

yea im trying to add dynamic bones and cant get nothing to work

been at it for like 3 days

There surprisingly arent really many tutorials on just adding dynamic bones to a skirt

[valid temple]

https://cdn.discordapp.com/attachments/806907605678424066/872995477057060945/VRChat_2021-08-06_01-11-20.mp4

finally made some physics work

[sage patio]

if it's rigged already, just add a dynamic bone component to the start of one of the bone chains, and set the "Root" as the same bone you put it on

that's all you have to do to make it work

the rest is just tweaking the values until it looks good

[feral sinew]

^

[jade bane]

Ohh I think thats one thing im doing wrong, I only have one bone in each point of the skirt which is connected to the hips, I need to figure out how to make bone chains then

[sage patio]

just set "End length" to some value

like 0.01

that'll do

[jade bane]

where can I find End Length? @sage patio

ahh I found it, let me try it out then

Yea doesn't seem to be working for me

[sage patio]

can you show me how you have your dynamic bone script set up

[rigid spire]

i dunno where to ask this but where did my model go? i bumped a button and now the mesh isnt showing up

[sage patio]

did you try just hitting Ctrl + Z lol

[rigid spire]

i'll see...

no it wont go back

[feral sinew]

alt+h

[sage patio]

@rigid spireclick this icon in the top right

the funnel one

click the icon that looks like a screen

[rigid spire]

@sage patio

[rigid spire]

alt+h doesnt do anythin

[feral sinew]

is the mesh still there?

like, in your collection

if so, try selecting it and hitting numpad .

[rigid spire]

its there on the top right

also i dunno what you mean by numpad, is there a button marked numpad?

[feral sinew]

do you have a numpad?

on your keyboard, i mean

[rigid spire]

yea.. its a laptop

[subtle pivot]

I was trying to get a good rig for avatars I can't find any tho

[rigid spire]

wdym rig? like.. finding a model?

[subtle pivot]

Something like that yes

[cosmic nimbus]

You wanna just import a skeleton?

[subtle pivot]

Mhm I'm trying to do

The skeleton was upside down

[cosmic nimbus]

Just make it from scratch or use Adobe mixamo

Mixamo isn't very good but it's about 1000x faster than doing it from scratch

If you're inexperienced, at least

[subtle pivot]

I need a humanoid one tho but it's fine

[cosmic nimbus]

Mixamo generates humanoid vrc ready armatures

automatically

[subtle pivot]

I see

[cosmic nimbus]

Yeah you just gotta feed it your fbx and it'll do the rest

[subtle pivot]

Is it free to use?

[cosmic nimbus]

Again the quality isn't commendable but it's quick and easy

And yeah free

[subtle pivot]

Ok then

[cosmic nimbus]

At least it was last time I checked, adobe being adobe things may have changed

[subtle pivot]

Oh

Thanks for helping tho

[jade bane]

Happy to say I did some other things that got the skirt working with dynamic bones 🙂 only problem I have now is the legs are going through the skirt a bit

[rigid spire]

i still need help with this

[sage patio]

https://www.youtube.com/watch?v=SimRLR_lRcA&t=1151s

@rigid spiretry switching to the Solid rendering mode

the 2nd one

[jade bane]

Ohh god I been avoiding the whole weight paint thing until now, just looks stressful lol

[sage patio]

not that bad

if you want your skirt to look right then this is the way to do it

either that or using Cloth, but that's too computationally expensive if your skirt is too high poly

essentially calculates physics for every vertex

[jade bane]

I feel like I have made so much additions to my character in unity, each clothing item is a seperate object.. I would need to go back to blender and re-do the base, then somehow slot it into unity in the place of the existing base? I dont even want to think about that with how many thing I got attached to the armature lmao..

[sage patio]

any edits to your model should be done in blender so you avoid all this hassle in the future

clothes is the #1 thing that should be added in blender

I'm gonna assume that you unpacked the model at some point

[jade bane]

yes

[sage patio]

which means that it no longer references the original FBX

that is something you should never do

because if you don't, then you can just replace the FBX with a new version (directly exported from blender for example) and unity will update it in the scene for you

[jade bane]

Ohh I was wondering why it wasnt unpacked in people tutorials lol

[sage patio]

unpacking models bad

[jade bane]

ohhhh I see

So shit I gotta basically start from scratch more or less

[sage patio]

it's for the best

also

do I dare ask how you added the clothes in unity...?

like your process for doing that

[jade bane]

yea soooo I add the clothing item with a armature then match the bones

but first I fit it to the base in blender

[sage patio]

huh

that's such a weird way of doing it lol

[rigid spire]

you unpack a model when you're adding something like a springjoint or something with a lot of coding

[sage patio]

no you don't

[rigid spire]

yes you do

[sage patio]

you can add anything onto a model without unpacking the model

you just can't re-arrange the structure of the model

[rigid spire]

but it wont work properly

[sage patio]

that's an edit that needs to be done in blender

[rigid spire]

to add a springjoint?

[sage patio]

no, rearranging the model

[rigid spire]

a springjoint is all unity

[jade bane]

It works perfectly lol

[rigid spire]

i wasnt talking about rearranging the rig

[sage patio]

springjoints should be put on the root of your model, and using a joint to fix it to whatever bone you want

or constraint

[rigid spire]

you rig them to your index finger in unity. to make it work properly you need to unpack the model completely

[sage patio]

you really don't

I've set up springjoints before bro

I would not be saying this and pushing my point if I knew that it didn't work

there is no reason to ever unpack your model. prefabs like spring joints? sure, those you can unpack.

if for some reason you need to unpack it, then that means you're trying to do something that should be done in blender anyways

[rigid spire]

without unpacking the model, to add something like a springjoint, it will not properly contraint to the finger itsself. it will be 50 feet away from your actual avi. unpacking the model completely is important for that so you dont actually fuck up what you're trying to do

[sage patio]

I have a model, which has a springjoint, which is not unpacked. the spring joint works just fine.

your issue is most likely unrelated

[rigid spire]

i find that mildly unlikely but whatever. if you model is the same in your banner, it comes pre-fucking-unpacked

[sage patio]

the model in my banner is a Coppouchi, and my current model is a Kitabunny. neither of them are unpacked. I edit all of my models in blender, and export them as an FBX, which, once in unity, I do not unpack

[rigid spire]

i just think you should just stick to your expertece of giving people blender help than unity help cause, yes, redoing the rig in unity for something like a skirt wont work, but adding something with a lot of unity things like a springjoint, a phone with playable music, a throwjoint especially, needs to be completely unpacked. that is wrong to not unpack a model completely to add something with lots of coding and uses things like the unity springjoint and constraint system.

[sage patio]

I have plenty of experience with both Blender and Unity, more in the latter if anything.

here is an example of a complex prefab, the VRLabs 3.0 Follower. if you notice, at no point do they unpack the model, and it works just fine. https://youtu.be/gSDRDISDSIA

and here's a spring joint tutorial; again, no unpacking needed. https://youtu.be/YQiBD08P42k

working on models is so much faster if you don't need to copy over shit any time you edit the model. you can just export from blender directly into your Unity folder where the FBX is, and Unity will update the model in the scene, no extra work required.

[rigid spire]

https://www.youtube.com/watch?v=umA9b7Yet1o&t=110s

unpack, the model, completely

[elfin nexus]

So i updated my avatar to see if this bone structure would help with some stuff, but instead now my hip is being rotated like 20 degrees sideways in fullbody. So i decided to set the bones back to the exact values that they were before, and the hip is still sideways, any ideas?

[muted mason]

Hi! I'm a bit new to uploading avatars to VRchat, and I can't quite find any tutorials/examples on how to add hair physics to my model. I imported my model with UniVRM to Unity 2018, and I want to add the hair physics back. Is there any way to do that? I've seen other models w/ working physics

[sage patio]

that's done with Dynamic bones, a third party asset which you can get on the unity asset store

[muted mason]

ahh okay, bless

thank you!

[fading verge]

does anyone offer fbx model rigging services? I have an avatar in fbx format from sketchfab I want rigged

[sage patio]

you can probably find someone to do that in VRC Traders #community-servers-old

[fading verge]

thanks

[muted mason]

Alright so I got dynamic bones and rigged the hair/skirt/chest/etc, but when I took it into VRchat then the models physics don't work. Any idea how I can fix that?

[sage patio]

firstly, you can test it in Unity play mode by dragging the model around. for every dynamic bone, did you make sure to drag the bones into the Root slot of the dynamic bones?

if you add a dynamic bone script to the tail for example, you need to drag that same bone into the Root

[muted mason]

Mhmm! I got everything properly rigged in unity, I just can't see it when I go ingame

[vivid carbon]

you might have dynamic bones limited in vrchat

[sage patio]

^

[vivid carbon]

if it works when testing in unity but not in vrchat, that's probably it

that is found in Safety->Performance Options

[muted mason]

`BLESS

thank you

[clear forge]

I'm not sure where I should ask but I guess here. So I've made an avatar from Blender and just exported to Unity. But when I go into playmode, it becomes like this. I think I must have forgot something from Blender, but I don't know what. I'm still kinda learning from Blender stuff so any help would be appreciated !

[humble gazelle]

Does vr chat support shrinkwrap?

My character has shrink wrap eyes

[crisp tendon]

Shrinkwrap should be applied on export, since Unity doesn't support it

[humble gazelle]

but i need the shrink wrap to prevent the eyes from clipping throught he model

[humble gazelle]

guess ill try to carve out the eye hole instead

[humble gazelle]

aaaannd blender swapped all my vertex groups around so now ive lost 2 hours of work

perfect

[turbid spear]

You can just rename v groups

[feral sinew]

It looks like you didn't weight paint the arms

[fading verge]

^ you might as well delete part of the arm mesh that is hidden under the clothing assuming the hoodie is not going to be ever coming off

[feral sinew]

that too

it's better for performance overall

[analog bough]

Is the neck bone used or is everything based on the head bone?

This avatar originally had a very small neckbone between the head and chest, and I'm not sure if that's because the neck doesn't matter or because the rigging is bad

Last time I fixed it by making the neck necklength and head head length but wanted to make sure that's the correct route before doing it again

[crisp tendon]

Neck is used, but not much, its weight paint is important though

[analog bough]

Alright I'll make it bigger again

Thanks

[spiral helm]

can anyone help me fix my avatar's eyes? they go cockeyed in play mode in unity.

[humble gazelle]

fixed my model gonna export it to unity

[humble gazelle]

is there a way to assign the visemes to only affect a certain vertex group?

[sage patio]

@humble gazelle go to blender, and try activating one of the Viseme shape keys

and see what happens

[humble gazelle]

it get all distorted

i think ive fixed it now though

i propigated to blend

[sage patio]

good

there's also Blend from shape which is kinda like the opposite, so it's more precise

[humble gazelle]

now hes not broken but he's to emotive

fixed it

just had to turn down the shape key mix intensity

shrunk him down because hes supposed to be smoll

[humble gazelle]

how do i turn shape keys into an expression i can use with the hand gestures

[sage patio]

the gist of it is that you use the GestureRight and GestureLeft parameters in your FX controller to control animations which in turn animate the shape key values

for the FX controller, you can take the Gesture controller template (called vrc_avatar3HandsLayer) and modify it

start by making a copy of that controller and calling it FX

after that, there are 3 things you need to do

1: remove all layer masks (click gear icon next to layers, remove the mask)
2: enable Write Defaults on every state in both hand layers (including Idle)
3: remove all the animations in every state in both hand layers (including idle)

now finally, you can create animations for the expressions, and put them into the states corresponding to the hand gestures

you can either put the same expression for both hands, or have different expressions on either hands

[humble gazelle]

How many keframes does the animation need?

[sage patio]

1

but you can do 2 if you really want

[humble gazelle]

so the animation is just one keyframe thats the blendshape at 100

[sage patio]

yep

[humble gazelle]

got it working thanks!

[sage patio]

np

[low fog]

iirc you can put the blendshape over 100 if you want (like 150). That way you can be overly expressive.

[wary nest]

forearm. 🙂

if by wrist you mean the hand bone.

[mighty pebble]

any reason why when I stand and touch my stomach, or lay down on my bed and touch my stomach, whatever irl. My hand goes halfway into my stomach instead of sitting on my stomach?

I used h on the 3rd pic to hide hair bones and in second pic I used alt+b on the right arm to hide the right arm because it's likely irrelevant to the armature

I believe I've tried moving the armature forward if I remember correctly, that's why it's further towards the front than normal and it didn't seem to do anything to fix the issue

[elfin nexus]

could be your viewpoint

make sure the viewpoint is just behind the ridge of your nose and not too deep inside your head @mighty pebble

[mighty pebble]

So yeah it's not as simple as my viewpoint after double checking

[elfin nexus]

necc

[fading verge]

mhm necc

[mighty pebble]

The Northern Essex Community College?

[prisma fulcrum]

OO oshawott!

[humble gazelle]

how would i go about playing a sound when a certain expression is made?

ive created a mgs alert expression

and im wanting to have the sound play along with it

nvm got it

[fading verge]

!

[fickle dawn]

ive gotten a random ping in here?

[jovial horizon]

i keep running into this weird problem with blender for my VRchat model. I went back to add bones for these ears and every time i start weight painting , even though i am only painting on the selected faces, They still get pulled randomly all over the body or some parts of it , so the ears get pulled in weird directions.
https://gyazo.com/34709914f82bd82a72d4b6b827f3ce66

[crisp tendon]

This means they are weight painted to other bones

[jovial horizon]

I know but i am not sure how thats even happening when i am using the selection paint and even hiding the rest of the model when i paint.

I painted the ear like this , im very confused how it even got attacked to any other bone when selecting the one bone at a time.

[crisp tendon]

Check the other bones and you'll find it quickly

[fading verge]

if you merged that mesh to ur armature with automatic weights it might of got some paint on it from nearby bones that you didn't intend to have influence

[jovial horizon]

I added this bones after finishing my weight painting when i had auto normalize on my first attempted the ear was painted to just about every other bone even though i selected just it.

I have wiggled about every other bone and nothing moves it.

https://gyazo.com/d4929b3fbe9681ddd854f7710177921f

There is every joint besides the chest/spinewhich im not sure how to lock the ear down while they move to test it

[crisp tendon]

and the other ear ?

[jovial horizon]

I haven't even started on that because this is the 4th time i reset lol.

i named the ears so the vertex groups would know which is which to mirror, that doesn't even work.

Hmm i don't know why but i think its the base bone of the ear causing it.

yaa it has to be when i got to rotate the ear from the base when just the base has all the weights, its causing the ear to shrink instead of rotate.

https://gyazo.com/f18cac877d66beb36cb5a2feb8309197

[crisp tendon]

That'd do it

[jovial horizon]

so D: how do i fix it

Or better understand why its even doing that.

[crisp tendon]

You only weight paint the bottom of the ear, because otherwise it fights all the other bones to move what's weight painted

[jovial horizon]

https://gyazo.com/6e10be9dc32007e8d87c87bbec65876c

Still happens its like its rotating based on something else

[crisp tendon]

No that seems correct

But other bones should move if they're parented

[jovial horizon]

ill try it some more

[crisp tendon]

Make sure that the other ear isn't responsible btw !

Since you fixed this issue

There could be more

[jovial horizon]

i don't think the issues fixed it still keeps scaling down when i rotate even after repainting

[crisp tendon]

probably means the other ear is affecting it

[jovial horizon]

https://gyazo.com/7aa932aab1012d5df81f27dfe285edd7 but there is one vert uneffected by what going on D: im so confused.

other ear has 0 weights

[crisp tendon]

Another bone might be responsible then ? Head or neck ?

[jovial horizon]

The head that was it

about time , thank you Ruubick

[crisp tendon]

[jovial horizon]

Its always the simple things...

[crisp tendon]

So simple that we discard them quickly

[prisma fulcrum]

CUTE

[plush sigil]

i keep trying to generate a rig and i keep getting the message "List Index out of range" Do i need to make a whole new skeleton to fix this?

[sleek radish]

Does anyone know where the IK for VRC normally twists bones?
I keep seeing people have janky/crushed/kinked elbows on wrist rotation, and I'm curious as to how the rig itself works so I can do twist bones correctly.

Since I can't realistically export rigify/constraints from blender to vrc unity (IIRC), I'm kinda stuck while rigging my model, and I don't really wanna spend days testing twist bones

[fervent hornet]

I dont think we've gotten a decent walkthrough of their FIK settings, but setting up your own FBBIK or VRIK in editor will give you something close IIRC

I know they've definitely changed stuff with FIK once it gets into game, but I don't know if they are using targets or rotation limiters or the like on the rig

[sleek radish]

Can you even do full body with your own IK?

I didn't wanna go down the rabbit hole unless I could, but that'd let me do really absurd stuff if so.

I wasn't sure if the full body in VRC was exclusively set for humanoid rig, or what

[fervent hornet]

You can do your own custom IK, its just annoying. You have the unity humanoid that VRC uses, then use the VR tracking points (Head, hands, hip, feet for FBT) for the targets in your own custom FBBIK that is on another identical rig

This was a common work around when they broke using FIK directly ontop of humanoid bones (not really used anymore due to constraints being a thing)

[sleek radish]

That'd double the bone count, wouldn't it?

[fervent hornet]

Yep :)

[sleek radish]

Eurgh

[fervent hornet]

I mean you only need to base humanoid for the VRC one, which is like 62 bones?

Oh no fingers needed so its less

[sleek radish]

Guess I'm stuck using the janky humanoid for now :')

[fervent hornet]

Yeah its jank, but they dont let us override the FBBIK they are using in game so you have to go around it instead

[sleek radish]

I'll maybe use IK stuff overtop for the muscles and a few others. I just hate having to set up constraints any time I make a serious update.

It's a shame, but I'm guessing that it's such a niche use case that it's not worth refactoring how they do fbt.

[fervent hornet]

Well you still need constraints for IK to work ever since they did net ik

[sleek radish]

Though, you could just have it point to bones on the IK in the avatar descriptor, and autofill for humanoid rigs...but that's likely a lot of work under the hood.

I just want my pectorals to move correctly T_T

[fervent hornet]

The main reason they probably arnt doing anything with FIK is because its technically working atm, and they want to replace it down the line anyways

[sleek radish]

Oh, didn't know that was a plan. Interesting.

[fervent hornet]

Its the same plan as replacing dynamic bones

[sleek radish]

I'm almost tempted to wait for the new physics bones update before I finalize this dingbat robot boyo, but then I'll be stuck with my current janky ybot.

[fervent hornet]

Heres a link to when we were talking about the future of FIK in beta talk #open-beta-discussion message

[sleek radish]

Lmao called it

[fervent hornet]

But yeah the physics bones update will be foreshadowing for how the replacement of FIK goes

[sleek radish]

The niche case use is always the killer

I totally get it tho

[fervent hornet]

Yeah its frustrating but working around exploits and other shit is kinda expected once things start to get complicated

[sleek radish]

Normies aren't the kind of people to make their own interfaces and perephierals and push limits, lmao.

I'm literally trying to work around buffer particles so I have one more particle effect available, lmao

[fervent hornet]

Getting called an advanced creator just because I place 4 VRIKs constrained to a body to simulate insectoid movement 😢

[sleek radish]

My current plan is to animate the emit over distance rate and wiggle the particle emitter for a frame or two, and then reset

Stupid janky.

[fervent hornet]

Honestly if you are doing anything with particle death you should wait for physics bones imo

[sleek radish]

Shhhhhh if I do that I'll be stuck with this thing

Instead of this boyo

[fervent hornet]

Oh I see what you mean by pectorals lol

[sleek radish]

Yessss

Also has lats. Both need a pair of bones and weird constraint shenanigans.

[fervent hornet]

Yeah that should be all constraints, FIK will just over complicate something like that

[sleek radish]

Yeah

[fervent hornet]

I've avoided stuff like pistons for no actual reason

[sleek radish]

I'm more interested in fik for this one;

[fervent hornet]

I could have gone my entire life not seeing that

[sleek radish]

Since the proportions are wacc

[fervent hornet]

But yeah you can always have a invis humanoid for VRC to play with, then use your own FBBIK/VRIK to try to match it in some way

Youll have more freedom to fix the jank if you use your own IK

[sleek radish]

Yeah. Gonna have to. I'm doing a rotation puppet thing right now and it's JANKY.

[fervent hornet]

Im just glad constraints are a thing, it was such a sad time before they existed

rigid bodies and fixed joints 😆

[sleek radish]

Eugh

Glad I came into it after that

[plush sigil]

Still need help with this if anyone knows

[vocal crystal]

hey if anyone can fix this issue with the neck id literally pay you 20 dollars. it seems that when i move the neck drags with my body which is kinda weird. someone told me the neck bone is too big but i have no blender experience and im not really looking to learn cause this is 1 problem. https://streamable.com/r6hnwd

pls ping me so i get a message

[crisp tendon]

Do you have a comparison with other avatars ?

[vestal condor]

how do I fix shoulders sagging down. vroid

[sleek radish]

Tpose.

Reset your tpose in blender so that the shoulders, and arms are planar on the z plane.

This will usually fix shoulder sag. If there still is sag, check arm length. Arms that are too short, or shoulder bones that are too long versus arm bones can cause excessive shoulder movement.

[vestal condor]

like so? Idk how to reset so I rotated in pose mode and applied it

[sleek radish]

Yeye

Make sure you have symmetry on as well

And that you still have a bend in your elbow.

A small bend in the elbow will help prevent screwy elbow stuff.

[little forge]

Anyone got a fix for the Hip-thigh rotation isnt 180°? which isnt cats

[crisp tendon]

Is your hip bone completely straight ?

[little forge]

yes

[crisp tendon]

How do you know

[little forge]

because it is

[crisp tendon]

Yeah, but i'm asking how you made sure of that, i don't know how experienced with blender you are

[little forge]

more advanced in blender but not so much in unity

but when i go ingame and try to use fullbody then the hip is bending forward

[fervent hornet]

I would raise the head of the hip bone and reset its roll as well

[little forge]

idk why but my hips was named after my leg bone then reassigned in unity, made error go away

[fervent hornet]

Yeah I always check everything that was auto assigned in the humanoid config, shit gets weird sometimes

[little forge]

or in another case when i tried to remake the footbone in blender and name it, it also named my weight painting from foot_R to foot_L
