[sage patio]

my bad

you just weight paint the moving part of the eye to that third bone

[lyric stratus]

wait so

sorry im new to all this

[sage patio]

this is basically what happens

from right to left: head, first bone, 2nd bone, third bone

[lyric stratus]

the eye itself and the pupil would be seperated in the way that if you clicked L on blender in edit mode it would select the pupil seperately?

[sage patio]

yes

[lyric stratus]

ok

thats fine

but like

one second

https://i.imgur.com/GtZktBy.gif

what stops the pupil from moving out the iris btw

like this gidf

gif*

[sage patio]

do you not know about weight painting?

[lyric stratus]

i do yeah

but like

[sage patio]

everything would be weighted to the head, and the part of the eye that's supposed to move is weighed to the third bone in my example

[lyric stratus]

i just know the basics i guess

[lyric stratus]

i thought the pupil is meant to move

so like

if the green on the gif is the white, and the blue is the pupil

if that makes sense

[sage patio]

yea the pupil gets weighed to the 3rd eye bone

the white stays put because it's weighed to the head

[lyric stratus]

ok

i dont completely get it but im just gonna try to replicate what youve done

sorry for being so new to this lol

[sage patio]

all good

basically you just want it so that moving that third bone moves the part of the eye you want to move

the pupil

[fathom sparrow]

Hey guys. I'm new. I got a somewhat vague question.. rigging is kind of making my brain hurt trying to memorize the process of rigging. Can anyone give me a general checklist for rigging models? I think having a cheat sheet will help

[lyric stratus]

@sage patioso i set up 3 bones like this?

[lyric stratus]

imo just watch the same simple tutorial a few times is the way i did it

[sage patio]

more like this

[lyric stratus]

? :D

and if i did that right, then i parent the big bone to the head, and the two tiny bones to each other?

and here is the eye mesh just to make sure im doing it correctly

ignore the topology

i will fix it

[sage patio]

@lyric stratus

[lyric stratus]

do i move them to the ends of the arrows or just futher right?

[sage patio]

that's the parenting order

you don't move them

placement looks fine

just remember that the Head of the bones (the circle near the fatter tip) is where it pivots

all 3 of the bones should be moved up so that the head of the bones line up with the center of the eye

[lyric stratus]

i think it would need to be moved down

right?

or the fatter nips needs to be aligned

[lyric stratus]

this good?

[lyric stratus]

also is this correct?

[sage patio]

yep, looks good

once you're back in Unity, add a Position constraint to the 3rd eye bones

with these settings (note unchecked Z, and ignore Pos. at rest and Pos. offset) then click Activate

[crimson plover]

Heya! Currently have a problem with a model I'm making where the characters Tposed in game despite it having a humanoid rig and such. Anyone know what step I might have missed when rigging the character?

https://gyazo.com/b6151891a56e92c89f255111c4c524d0

The character's rig looks like this in Unity, and I think I'm missing a bone for the upper chest and toes if that's what's causing the issue but not really sure. 🤔

(didn't know if this was supposed to go in help or rigging so sorry if I messed up the channels haha)

[forest swift]

Mabinogi to VRChat RIG from 0!

[gloomy rain]

I'm trying to make an avi for a friend, but noticed that the hoodie moves with the legs, which it shouldn't.
one side is fine just the left side is doing that? help??

[lyric stratus]

dont i have to weight paint it and stuff in blender? (sorry for the late reply)

[lyric stratus]

mirror the weights on the side that isnt

you can do that via a mirror modifier or mirroring the vertex groups

[lyric stratus]

(please ping me if you get around to answering so i can see it :) )

[sage patio]

yes you do

[lyric stratus]

should it just have the same weights as the head?

and what kind of weights should it have on the 3 bones that i added? just all the way red?

[sage patio]

the first two have no weights at all

only the final bone, the one closest to the eye, has the pupil weighed to it

[lyric stratus]

alright

[lyric stratus]

like this ? :D

[sage patio]

no, there should not be any kind of gradient

in edit mode, hit L to select the whole pupil. in weight paint mode, enable Vertex masking in the top left, set your weight slider to 1, and do shift + K

[lyric stratus]

ok

thank you so much for all the help so far by the way

[lyric stratus]

in the top left, i see vertex selection, and paint mask. which one is it?

i clicked this and

when i do shift k, it says this

oh i think i see why

haha im so stupid but it works now

now do i go to unity?

I’m trying to rig this model for an avatar/NPC, but it just doesn’t work for me… I don’t understand rigging at all… Can someone please help me understand?..

[lyric stratus]

also how should the whites be weight painted

[sage patio]

everything should be weight painted to the head like you normally would, except the pupils, which are weighed to the 3rd eye bones

[lyric stratus]

OK

[lyric stratus]

then what do i do?

[sage patio]

if you manually move that third bone, does the pupil move?

[lyric stratus]

https://i.imgur.com/dP7eXej.gif

the whites of the eyes are a bit hard to see but still

you can see they move with the head bone

[sage patio]

uhh this isn't as 2D as I thought lol

not sure if my technique will work for that

it seems to me like just having one bone per eye but placed far away from the eye would work best

the further away from the eye the bone is, the less it rotates on itself

[lyric stratus]

it was completely 2d but uh i changed it like this because this is how i though its meant to work

but i have one issue with a single bone like that

lemme make a gif

[sage patio]

so if you picture a large sphere that has the same curvature as the face, you want the bone to be at the center of the sphere

it doesn't matter if the bones go outside of the head or not

[lyric stratus]

what would stop the pupils from going completely off the face like this in that scenario https://i.imgur.com/rzdR9bW.gif

or just outside of the eyes

[sage patio]

well first, they should be inside the head, not outside

[lyric stratus]

thats the thing

i want it to look as 2d as possible

[sage patio]

you can have the eye sockets be intended but not look like it if you're using flat shading

you can also edit the normals to all be facing forward

[lyric stratus]

but if its not gonna work outside though i understand

[lyric stratus]

how would i go about this

[sage patio]

that would be a poiyomi shader thing

but just having the normals aligned would help a lot

[lyric stratus]

how do i manually align normals

i know how to like

recalculate them

[sage patio]

separate the eye socket mesh, add a NormalEdit modifier, and apply it

before and after

normal editing is a common thing when making stylized/toon models

[lyric stratus]

oh yeah

i know about this ok

so

i should model eye sockets into the character?

[sage patio]

I would recommend having eye sockets, and having the eyes moved back to be in them

that way, the eyes can move to the side and look fine

[lyric stratus]

and there is definetly no way to do it if the eyes and pupils are images like i can in blender?

its not the biggest deal if not

[sage patio]

not if you want to use VRChat's eye look system

if you have a headset like the vive pro eye or varjo aero, you can use the eye tracking to drive animations that move the eyes by moving the textures, like you did in blender

but there's no way that I know of to drive a texture offset using bones

[livid flume]

What do you need for a avatar to be uploaded to vrc?

and do I need shoulders to upload a animatronic avatar?

[lyric stratus]

oki

i will try to make some eye sockets

[scarlet hare]

hello! I have a quick question regarding rigging my vrchat avatar?

can you have the head bone detached like this?

its still parented to the neck bone...

[sage patio]

you can, but remember that a human will be wearing that avatar. you should do your best to make it follow the humanoid skeleton as closely as possible

you should also straighten the spine

having the head bone further forward like that might lead to some weird bending/viewport drift, but only one way to find out right

[scarlet hare]

?

huh

I cant post the pic

[sage patio]

you could also use extra, unweighed bones for the neck and head, and have those be perfectly aligned like a normal human

and then use either constraints or FinalIK to drive the actual neck/head of the shark

[scarlet hare]

my pics are being blocked?

[sage patio]

odd

[scarlet hare]

welllp

idk how I can ask if its better if I cant show it

so wait if I have two head bones...how do I dictate which one is actually used for vr?

or does it just assume the unweighted one is

@dawn oak the bot seems to think my images are explicit? is there a fix to this?

[dawn oak]

If it's the discord clyde bot, not anything I can do about it

[scarlet hare]

damn

well thanks for the reply

:I

is this straight enough?

[sage patio]

use pose mode to fix the spine

[scarlet hare]

how come? :o

[sage patio]

your spine is heavily leaning forward

[frozen cipher]

For those of you who rig digitigrade legs, do you also create digi toe bones? or just have the planti toe bones. Ive been following the DragonSkyRunner/kaideart tutorial but man do my avatar's toes get fucky when modding poses to work with the leg digitigrade leg rig

I didnt see anything in those tutorials about creating digi toe bones, just the normal planti bones

[weary zealot]

Hello everyone, should i put a upper chest bone on my rig?

[young wind]

im no authority on rigging but i suppose it depends on if youd like to have better twisting in the torso if i remember my rigging courses properly

unrelated, anyone have tips on how i should lay out bones for this stupid jacket. i should never have designed it like this

[sage patio]

yes, the new IK prefers having an upperchest

[naive ermine]

Hello, say I have fbx model but its rig is ugly. Where can I get minimalistic human rig which has everything and optimized for VRC (all bones for default animations, jaw, eyeballs, conventional names and hierarchy)? Everything I've downloaded has some extra bones and other stuff from I guess some 3dr party rig software. I just want to paste it over my model and weight paint it from scratch.

[sage patio]

Gumroad or booth.pm

[frozen cipher]

You want to animate the curtails? or the sleeves as well?

[young wind]

the curtails only, sleeves r just the arms

[frozen cipher]

I would make a root bone around hip level, and then make chains of bones where you want those curtails to deform. Then weight paint the lower end of the coat to those bones. I am by no means an expert, but thats how I would do it from what Ive seen from people animating clothes with dynamic bones

So if you wanted to make it simple, Id have your root, then maybe 4 different chains of 3-4 bones each parented to that root. (one chain per section of divided section of coat) If that makes sense @young wind

If not, look up a dynamic bones tutorial on youtube how they do clothing for skirts and whatnot

[young wind]

alright, cool! that's what i was thinking of doing, ty for your thoughts

[prime quarry]

anyone know why my model's pelvis is leaning so far forward?

[lyric stratus]

i have made the eye sockets

the eye is now in an eye socket and the white and pupil are seperate and not textures

[turbid venture]

does anyone have any suggestions on how I can stop the wrists from curling like that? I've been messing with the positions of the bones but nothings helping

[pastel bough]

^ Kind of on a similar note, is there an easy way to adjust my avatar's resting posture? Mine is currently a bit slouched and has its feet pointed inwards compared to other avatars. Do I just rotate the spine and legs in blender or is it way more complicated than that? 😅

[sage patio]

download the CATS blender plugin, go into Pose mode, tweak the pose of your model, then click Apply as rest pose

[pastel bough]

Awesome, I just installed CATS a minute ago. Thank you 🙂

Wow that worked beautifully. Too easy and it looks perfect now. Thanks again!!

[lyric stratus]

@sage patio what should i do next, is there a tutorial?

[covert ember]

I'm trying to make new shapekeys and contrary to my last attempt that I did with cats blender plug in, I wanna make them from scratch and try to make them match my actual mouth movements better. Any tips or tricks on how to do that? Like, is there stuff that I should avoid/definitely do?

[sage patio]

if you're making mouth movement, ensure you have a jaw bone. you can use pose mode to create shape keys

you can also refer to the Oculus Viseme Index for references

if you have a furry avatar, this might be helpful

[fading verge]

r

rato

Cuuute

[covert ember]

humanoid, but helpful nonetheless ^^

thanks ^^

[turbid venture]

does anyone know why the thumb is going so far out?

[sage patio]

because that's not how you rig a thumb

not sure why there's an extra bone chain lol

[rose jacinth]

I dont know if this is the right spot to ask but is there someone outthere who can add a model into vrchat for me

And add bones as well ?

[pastel loom]

Any of you rigging wizards know what causes this hip issue with FBT? Its been a long while since I've run into this issue so I can't remember the fix at all

[robust crescent]

compare it to the pic above here, im guessing your hips way to low/odd

[pastel loom]

I remember seeing something about the position of the hip bone itself, but I can't remember, does it need to be above or below the top of the thigh bones?

[ornate cairn]

above

it also needs to be pointing at spine

[pastel loom]

Will try those, thanks

[turbid venture]

I've fixed the way the thumb/hand was rigged but I still cant get the thumb to stop stretching out like this, does anyone have any suggestions?

[languid pewter]

hvae you tried just unbinding the first bone in the thumb

idk if thats a good solution atall

[turbid venture]

it looks like that helped the way it was distanced from the other fingers, but it still looks strangely long, I think I can fix it on the mesh though

[pastel loom]

interesting that Discord counts a screenshot of my rig as NSFW content, I was about to send a screenshot

[pastel loom]

I've tried a bunch of things from moving and rotating bones to reordering them in the heirarchy with absolutely no changes each time.

The hip still comes out twisted but only after I calibrate, it's fine in animations

I feel I should note though, the RIght Thigh bone does a similar thing, and I have to account for it by offsetting it 90 degrees along its Normal Z

or rather, all of the bones are offset by 90 due to being from a different engine, and I was able to get away with rotating them each 90 degrees but the Right Thigh I had to leave in place

i.e.

[weary oak]

Reset your bone rolls in blender if you haven't already (Select all bones > Item tab on the left > bone roll '0' > right click > copy to selected ), then change your rig from humanoid > generic > humanoid so unity updates to the new skeleton config
Also if you're importing an FBX from another engine, there is an import option under 'armature' that lets you change the primary/secondary bone axis so you don't have to rotate everything manually, just FYI 🙂

As far as your fbt issue, maybe its coming from how the legs are spread like that? I'm less familiar with fbt setups, but I know the legs are supposed to be basically vertically aligned along the joints... Like, if fbt made the one leg straight down, maybe the other would be sticking off to the side the way you described, and the rotated thigh bone could just be introducing more jank elsewhere after the fact
Mostly guessing though I'll admit

[void canyon]

when you get a new head and it is too galaxy brained compared to your old one

bursting at the seams

[void canyon]

halp

I generated the Right/LeftEye bones via CATS and they work fine on the rig mapping configuration:

however when i save the mapping, the eye is gone

seems to be skewed somewhere like this above the eyeball

since the iris is outside of the eyeball, no amount of fiddling with the rotation states seems to line it up

i'm pretty lost, it works perfect in blender, works perfect in the bone mapper/muscle tester in unity

but it dun work

[languid pewter]

i never feel like im using the right channel, but what can make the pose slightly different between unity and blender

[robust crescent]

Those eyebones looks way too high up

[void canyon]

this is how it's setup in blender

maybe the base head had the original eye bones too high up?

so weird that it works fine on everything else lol

[weary oak]

Did you try rotating the eyes 90 degrees X in the rotation states here?
Also if the original rig came with eye bones why generate the eye tracking with cats? Am I missing something that cats does special?

[ornate cairn]

do you have 2 bones for each eye? that is not something that should happen

[void canyon]

the eye is too high in the skull, it doesnt show up

[void canyon]

its the base eye bone, they're skewed so it does not work in unity

well, at least they are in eye-socket height

i guess

[weary oak]

Adding to Z in the rotation states might help that
Hard to tell with just these screenshots what all is going on though

[void canyon]

yeah

basically, the base eye bones work, but they're not aligned right so it comes out cross eyed in unity

the CATS generated eye tracking, based on those two eye bones, have the pupils show up way too high in the model

i havent had the chance to see whether they're aligned right or crosseyed lol

basically, i had these eyes, i went into the eye tracking like so:

and then it generated these two upwards eye bones for me

the bottom bones make me look crosseyed, the CATS bones are straight up gone

[weary oak]

So you imported to unity, saw the eyes, went into blender to generate the new eye bones, and reimported to unity?

Idk why the original eye bones are offset like that, that's weird tbh.

[void canyon]

basically, yes

[weary oak]

Did you reset bone rolls before exporting from blender, and change rig to generic and then back to humanoid in unity after you reimported?

[void canyon]

i did the generic bit, but not the roll bit

let me try it

[weary oak]

Bone rolls do crazy things I've found lol

[void canyon]

welp

all 4 of them are on 0 degree roll lol

[weary oak]

Well at least we've eliminated that as a potential issue

Are any of your bones in Blender posed, or are you in base rest pose?

Those original eye bones still bother me lol

If you wanted to send me your model, or stream for me I could help you troubleshoot.
Only if you were comfortable with that of course.

[void canyon]

I should be on rest, but let me clear transforms real quick

[void canyon]

Haha i might take you up on that if i can't figure it out, but i'll try a few things here

i adjusted the eye bones to look less weird and it seems to have made it better?

made them look straight out

smack dab in the middle

it woooorks, but the rotation to make it look forward is weird

aha!

i straightened them upwards like this

and it works perfect

[weary oak]

Sweet!

[void canyon]

you were right, the original bones were f'd up

thanks man 😄

[crisp tendon]

Did you apply your pose and cleared your bone rolls ?

[weary oak]

No prob, glad I could help 😄

[languid pewter]

fixed it by accident and im not sure how, i probably didnt do the second thing

[crisp tendon]

[scenic ridge]

need some help

[void canyon]

my crystal ball just happened to malfunction today

can't help if ya dont mention the issue

[buoyant dove]

so if im using a four legged animal what would be the best way to have them walk correctly

like i know theres a special system for spiders but would that be effective on this

[sage patio]

you would need to use FinalIK to get it to walk properly. pretty much the same system that spiders also use

[buoyant dove]

is there a free one

[sage patio]

no, but FinalIK frequently goes on sale for 45$ in the unity asset store

another option that might not be as effective but still looks okay is to have rotation constraints on every bone of the rear legs that are constrained to the front legs

depending on how they're rigged, they may not work perfectly

but worth a shot

[fervent hornet]

Constraints are the free way but they are 🤢
FIK is the good way but its fucking 💰

[nimble crescent]

all i did was change a eye texture

[tribal isle]

is there anything I can do to avoid this weird spike effect when adding springbones?

these are the values

[fluid flame]

So I believe this is the right channel for this but my model is constantly stuck in the ground like this and I cannot figure out how to fix it, the camera is at the correct height but the rest of the model isn't.

[fair plank]

Is it set to a humanoid rig?
Is the locomotion layer broken?

[fluid flame]

It is set to a humanoid rig yes, and I am unsure of how to check if the locomotion layer is broken or not, it walks perfectly fine just visually in the floor.

[fair plank]

Ah is the origin correctly set in Blender/3D program of choice? maybe

Like in Blender are the feet below the 0 point?

[fluid flame]

the origin is right between the feet

[fair plank]

Is this a new issue for this model?

[fluid flame]

I'm trying to upload it for the first time

I made this model myself so there's no base

[fair plank]

Gotcha

Bones in the right order?

[fluid flame]

Yes, I found out that in the rig menu it was below ground, but not in the standard viewport so I was confused

thank you for helping me though

[whole valve]

Im trying to rescale my avatar to more human-like proportions and whats resulted from that is when i sit down (on a chair with my legs/knees bent on a 90 degree angle) and rest my hands on the top of my legs, my hands now go through my legs.
I can't figure out what aspect of the avatar i need to change in order for that hand-to-leg contact to be accurate again. Is this related to where my hip tracker lines up? Is this related to arm/leg length ?(i tried shortening arms but didnt appear to have any noticeable effect)

[fair plank]

Try using this
https://github.com/triazo/immersive_scaler/releases/

[whole valve]

I did initially try this, but it just gives me an error in blender when i hit rescale 😦

I guess i mostly am trying to figure out what body part ratios decide how far down my hands will go (so i can adjust those and bring that level up to meet where my legs would be when sitting down)

[fair plank]

There's some FBT scaling related vids on Youtube it's a bit more of a process since it's basically all manual but it'd presumably work

[fair plank]

Ah, I found that the one with Cats addon doesn't like seperate meshes if I remember correctly
and also stopped resetting the origin so I had to manually move my avatar down so it wasn't floating

[whole valve]

Yeah I always try to follow Kung's video but never get a satisfactory result - I assume there are just some aspects I'm overlooking.

[fair plank]

Gotcha
Good luck

[sharp gyro]

Dunno if this is the perfect channel for this, but is it possible to make an avatar that's just a walking box on legs? No articulation or moving parts above the hip. I'm a complete newb who doesn't really know what they're doing, I imported two source engine models into blender and merged them, trimming off most of the stuff I don't need. Need advice on how to proceed to make this a usable avatar, if possible.

[ornate cairn]

just have weights on your leg bones and rest of the bones do nothing

easiest solution

[sharp gyro]

Honestly, I don't know enough to know what weights means in this context. Is there a like a 'VRChat avatar creation for dummies' guide out there? All the ones I've found so far are for customizing existing humanoids

[ornate cairn]

this avatar seems to have rig is it rigged?

[sharp gyro]

Well, it came with a skeleton, so maybe? It's from team fortress 2, not designed for use in vrchat as an avatar. I deleted the parts of the skeleton related to the arms and head/neck, but I've let parts of the spine just in case. The upper box part isn't linked to any of the joints, so it doesn't move when the skeleton is manipulated (unlike the legs)

[ornate cairn]

well you need full humanoid rig for it to work but all the bones above upper legs won't be moving anything they will just exist so unity will mark the rig as humanoid

and that's all

[sharp gyro]

Ah, that makes sense. Since I deleted the original bones, is is possible to make new ones in blender?

[ornate cairn]

blender is tool for nearly everything in 3d so yes

[sharp gyro]

Also wondering if it's possible to make it simplified to save time. Like, do I need multiple spine bones, or is just a straight spine okay? What about fingers?

[ornate cairn]

i think you can use addon called rigify and generate full rig

[sharp gyro]

Gotcha. Hopefully I can preserve the existing rigging in the legs

[scenic ridge]

need some help

[sage patio]

you need to follow the standard rig

here

in your case, you'd probably want to have the whole box weighed to the Hips

and then the legs rigged normally

every other bone will do nothing

but it's required for it to be considered a Humanoid rig

some bones can be omitted, namely:

• upperChest
• fingers
• toes

[sharp gyro]

Much obliged!

What I need to figure out how to do now is assign bits of geometry to different bones. Mainly, the box part I'm adding to... maybe the chest or part of the spine?

Actually, is it possible to get the box on top of the legs to always remain upright? So if I crouch down, lean around, etc., the box doesn't tilt, nor would it sway around when moving.

[sage patio]

that's called Weight painting

[scenic ridge]

idk what im doing with unity\

[sage patio]

the way you get parts of a mesh to move with an armature is by assigning vertices in that mesh to Vertex groups. if a bone shares a name with a vertex group, then moving said bone will have the effect of displacing every vertex in that group, proportional to the weight given to each vertex

weight painting is just the process of mass-assigning vertices to vertex groups using brushes

[sharp gyro]

I think I sort of understand this. I get that when vertices are paired to a joint, they move with it... but this sounds like they can move at different rates based on weight? Is the weight for simulating physics in dangling bits like hair or skirts?

[sage patio]

if you take a knee joint for example, there's a weight gradient for the upper leg group and the lower leg group

at the knee

[sharp gyro]

Is weight just a term that's being used for this, or is it actual weight in lbs or kgs or something?

[sage patio]

weight means "influence"

like in a "weighted average" for example

[sharp gyro]

ah

Okay, I think what's confusing me is why a joint would have a weighted influence on the vertices paired to it. I'd think they'd just move with the joint, or not? Like if I move my arm IRL my skin just moves with it

[sharp gyro]

Oh it's for the joints!

[sage patio]

red = 100% weight, blue = 0% weight

green 50%

[sharp gyro]

Ah, so it's to simulate soft tissue or materials deforming and flexing

So for something like a robot, where no pieces are deforming, just a bunch of solids linked together, can you omit a weight gradient?

[sage patio]

yes, you would simply assign a weight of 1 to the vertices

[sharp gyro]

Is this possible or nah?

[sage patio]

yes

add an extra bone, have it parented to the hip bone, and weigh the entire upper body to it. then in Unity, add a Rotation constraint to it, and have it target the Armature object. in theory, that should work

the Armature is not supposed to rotate, it should just stay upright

you would maybe want to uncheck the Y axis in the rotation constraint, so that it can still turn side to side

but not tilt

[sharp gyro]

Perfect, thank you!

[sage patio]

speaking of constraints, you could use them for things like kneepads

which only move 50% the amount that the lower leg does

you'd have an extra bone for the kneepads, parented to the upper leg. then you'd add a Rotation constraint to it, set the source as the lower leg bone, and set the weight of the constraint to 0.5

[sharp gyro]

Alright, I've exported that model as an fbx, and reimported and 'fixed' it with the CATS plugin. Obviously the skeleton is a little messed up, is it possible to do a little surgery with the armature template you sent me? Join the upper body of the template armature with the pelvis and legs of the one I have.

[sage patio]

yea, you can just import the template armature, delete the lower body, delete the upper body bones in your rig, then join the template armature to your rig

then parent the bones the right way around

[sharp gyro]

👍

[sage patio]

don't forget to add an extra bone for the "box" of the avatar

parented to the hip bone

[sharp gyro]

hmm, what about height? It seems my model is several orders of magnitude larger than the armature you sent. How tall would that armature be in-game? Is there a 'vrchat unit' that needs to be converted to blender units?

[sage patio]

both blender and Unity work in meters. if you create a default cube in blender, it's 2x2x2 meters

[sharp gyro]

oh perfect, metric units!

[sharp gyro]

Speaking of this, is there an easy way to select the box to make it a vertex group? Since opening it with CATS, it's become purple, which I'm guessing means it's unparented to any bones, so I'm hopeful that there's a way to select all of it at once instead of... grabbing each vertex individually

[sage patio]

you can just select those pieces in Edit mode, and then assign them all to the group you want

to select stuff, you can hover over a piece and hit L to select all of the connected vertices

can also enable X ray mode, select an area, and do ctrl + L to select everything else connected to what you selected

[sleek isle]

One thing I not sure about rigging. Why some character eye tracking durp a little ? Joint to close to each other/orientation/ etc.

[sharp gyro]

@sage patio Sorry to keep pestering ya, but how do I actually parent this vertex group to a bone? I thought it was done by going into the constraint menu, making a child of the armature, then selecting the bone (as I've seen a few tutorials do it), but when I do that it shrinks the entire model down (legs and all) enough to make it nearly invisible, rotates it a random direction, and parents the whole thing at once.

I think the strange size change has something to do with the fact that I scaled the entire model down a while ago

[sharp gyro]

Wait, I actually did it! Sheer dumb luck, but I did it

trying to use blender is like trying to wrestle a bear

although now if I try to scale the avatar-in-progress back down to a reasonable size, the armature and the model scale at different rates

I have a feeling that I'm trying to do something that I need months of study to even comprehend

ctrl+z doesn't undo this... welp I tried, I think my work is lost

[sharp gyro]

I ended up remaking it, and it seems to be functional, it's at the correct height, and all the vertices seem to be paired to the correct bones

not even sure what I did differently this time

Now I just need to figure out why the two different textures are pink and purple instead of what they should be, despite both textures being loaded and the UV map panel showing them working as they were before...

[hidden ether]

Can somebody explain to me what the correct example of this is supposed to look like, or point me to a good example?

[ornate cairn]

second pinned message

[hidden ether]

oh, cool, thank you and sorry for not looking

[ornate cairn]

basically

[left brook]

hello I need help my avatar is standing on toes against on whole feets

[radiant verge]

Does anyone know why this happens?

[sleek isle]

Vertex group not matching the bone name

By the look of it, you probably merge twist bone or something.

[marsh flame]

Hello, I need a tip of advice. Basically my entire rig seems to be working perfectly fine (arms and legs have IK rig but deleting it didn't change the issue) but there's a problem with elbow doing weird things. Basically when I try to pose my character with hands nearby her face, the elbow does this. I've attatched pictures of weight painting, maybe I did something wrong there?

[crisp tendon]

You can extend the weight paint on each side more, but part of the elbow could be painted to something it shouldn't be

[gilded ibex]

when an avatar has that knee clasping problem, what are the bone fix in blender that can be made that are future proof? (not my picture, just for illustration)
already disabled the ankle bone inherit rotation.

[robust crescent]

Straighten the legs, those are when they arent

[robust crescent]

upper leg on that pic always bothered me, line is straight , bone is not 🔨

[gilded ibex]

like this?

[robust crescent]

usually from the front make those legs go cross

[sage patio]

no, look in the pic I sent

from the side, the knee should be bent. the same way your real leg would bend

from the front, it should be absolutely straight

select the leg bones (upper leg, lower leg, foot and toes), and do S > X > 0 > enter

[gilded ibex]

yes, this is what im looking for, thanks

yeah since this is the 1st time im doing the merge armature process, the resulting bone structure are a bit different from my usual routine.

[sage patio]

in this case actually, you might want to use pose mode with X mirror to rotate the legs outwards a bit

[void canyon]

any point to mapping the jawbone if all my visemes are setup already?

i have a bad case of mouth agape syndrome & i'm wondering if its worth fixing vs. just unmapping the bone

[sage patio]

no, just unmap the bone

you don't need a jaw bone for visemes at all, but it's useful to have for the purpose of creating shape keys

[atomic panther]

is there a reason that my avatar has the walking animation on PC but on oculus it's legs arent moving?

[void canyon]

did you disable these?

[atomic panther]

I hadn't clicked anything in settings except adding to the tail- I'm a noob.

(Currently I'm using physbones) - do I need to uncheck that or make sure it's checked?

[atomic panther]

figured it out- it had 2 separate rigs and it was messing with it (idk how but it did)

[hasty copper]

I'm having an issue where the Eyeballs when you click "play" in unity (They also show up in game like this). They move out of my head.

It looks normal, and I can do the "look up/down/left/right" eye movements and it looks fine.

Here are the two eye bones in blender

[ornate cairn]

try editing bones so they are vertical instead of horizontal

[hasty copper]

Other models have them like this. And it works in NeosVR like this..

[sage patio]

the bones should be facing perfectly straight up

[ornate cairn]

Noes works differently

vrchat needs them vertical so pointing up

[hasty copper]

Nope, didn't need to do that. I ended up renaming the bone from LeftEye to Eye_L and when I opened that model it complained about errors and I had to tell it where the eyes were and now its working.

Hey and that naming is also working in neos!

Well I'm glad I figured it out.

[hasty copper]

I'm pretty sure what caused my issue is the fact I'm still learning blender and this was my first time having to make a bone and vertex group.

And somehow I ended up with two bones linked to the eyes. And original I just told VRchat what bones it should use.
Where as NeosVR wanted the use the other bone.
So when I moved the bone Neos wanted to the same position and deleted the other bone.
VRchat still was looking in that lower position of the old bone it appears.

[mortal goblet]

If anyone has an example rig for a 4 legged animal please send it my way

[sullen goblet]

I feel that,did my first model model with eye tracking and stuff so I know how that feels

[brisk terrace]

I was wondering if there is a way to make a sleeve not rotate with the arm its on. My character has a coat that's kinda hanging on their arm and if i rotate my arm it also gets rotated with it. It has to follow the arm when its raised or pushed forward

[gleaming mesa]

Not in rigging itself, but when you go to vrchat. You would have to make the coat arm a separate bone at the same position as the arm bone and use constraints in unity to connect them in most axis except the rotational axis that is, uh, spinning the sleeve

Because thats what you want in the end, lock one rotational axis

[brisk terrace]

they are already using their own bone and i tried locking every possible combination of axis but the arm bone doesnt rotate on one flat axis ... when i rotate it on itself , it's using all 3

[brisk terrace]

see when i rotate the arm on the center axis , all 3 axis turn ... no clue why

[brisk terrace]

i went back in blender and made sure that the sleeve bone was in the exact same spot as the arm too

[gleaming mesa]

Still, try to make the constraint

The rotation shown in unity here is something, but it isnt local iirc

[brisk terrace]

i tried the constraint with ever combination of x y or z turned off and nothing worked

[keen jasper]

hey everyone i joined this server because i need some help. My name is alyssa and i recently bought and avatar off of gum road and i sent the files to a friend to upload it for me. it said it came with a quest version and file so that it works on quest too but the friend that uploaded it for me couldn’t figure it out so i was wondering if there was someone that could look into it for me and help me out. if you think you can help or know someone that can please DM me as i just ordered my vr and i’d love for my avatar to be compatible. ty! just do me if you can help <3

[formal hare]

Thats a bit vague for the specific issue but as you say they couldnt figure it out so if you havent already:
read the documentation, and look at some videos
tldr you have to switch unity to the android variant and upload with that

[short radish]

what is the best way to convert VRM spring bones (from vroid) to the new physbones

if I try to use VRM converter for VRchat all the spring bones dissapear and then I'm just left with the skeleton and no hair bones or anything to work with at all so i dunno

before convert vs after convert

nevermind i just did it through blender

[keen jasper]

tysm someone helped me and we figured it out ☺️☺️💓💓

[modern sorrel]

Someone knows why when I make eye tracking it only moves in place.? It looks weird when it does

[edgy willow]

dead ;-;

[void canyon]

hello, anyone know of a way to limit the range of movement on a bone in one direction, without dynamic bones?

i have this shoulder pauldron that i'd like to move relative to the shoulder+arm bones

right now the armor bone is parented to the shoulder, so when i raise my arms, the thing clips:

if i parent it to the upper arm, the armor moves too much (left is parented to the arm, right is parented to the shoulder):

Is there any way to make it so when i raise my arm, the armor raises as well, however when i put the arm down the armor levels and stops horizontally?

[robust crescent]

Merge shoulder pad bone to arm / parent it to arm 🤷

[void canyon]

refer to the second picture, if i parent it to the arm then it does not level horizontally when i put the arms down

[void canyon]

like this ^

[fading verge]

There's no good way to get pads to stop in a certain position. I've tried to no avail

[void canyon]

:( aww

im not particularly skilled at blender, so i guess i'll have to live with it haha

[robust crescent]

if its pc, you could try constraint in unity

[void canyon]

i'd like to make it fallback compatible, are these constraints disabled on the quest?

actually, unity and not blender?

[robust crescent]

They are not

pc one could use it, quest would have to remove em

could still be a fallback just quest one might be bit derpy shoulderpad

majority would never actually notice it anyway unless you point it out

[void canyon]

haha, you could say that about most small touches i've done so far

😂

30 google tabs deep on a topic later: "man, it doesnt actually matter"

[languid pewter]

my friends always say people will never notice stuff lol

[brisk terrace]

im running into a problem with full body only. body parts get mapped to the wrong places and the model collapses

the model works fine without full body

[spare perch]

i added blend shapes to my model in maya for blinking and visemes but when i import the model to blender the face is all messed up

😰 jesus

flipping the normals does nothing somehow

importing with custom normals disabled seems to fix it?? i think?? idk what else is gonna be messed up tho

[spare perch]

do the eyes need to be combined with the body mesh for cats to do the eye tracking?

[sage patio]

you don't need to use the CATS eye tracking thing at all

all you need is for your avatar to have its eyes weighed to eye bones

[spare perch]

oh nice

[sage patio]

they should be part of the same mesh as the body

the bones should be pointing straight up with no roll

[spare perch]

welp

parenting them to the body mesh wont do right

[sage patio]

no, you should first have the eyes weight painted to their respective bones, and then join the mesh

[spare perch]

ill have to redo the bones cuz i made em like this

thanks for tellling me tho

[sage patio]

you can just rotate them

also, make sure the bone is in the correct spot

the head of the bone (the fat part) is the pivot

[spare perch]

you mean the sphere?

yeah the eyes are weighted to them

[sage patio]

okay cool

[spare perch]

yeah combining the eyes and the mesh is just not working out for me

to export the fbx id need to get rid of the non deformer history

which it wont do after i merge them together

[spare perch]

Oh god do i need the mouth parts to be merged with the body as well for the visemes
I can make blend shapes for each part with cats but im scared thats not gonna work out in game or in unity

[karmic basalt]

Hello fell people of the internet

Anyway. If anyone who make models from scratch has time to help, id love some help

I have an obj file that i have rigged myself, all the bones and such work and everthinh

All that is to do is to import it into unity and also i need the uv map to colour it

Im not sure how to do this so any help or tips would be appreciated

[novel aurora]

You have to manually set up the UV map in Blender or whatever program you’re using, otherwise you will have an untexturable jumble of polys

[karmic basalt]

Okeoke

How do i do that

[pale ingot]

im fairly new to avatar creation so this might be a stupid question, but if i wanted only the pupils of my avatar to glow but the eye is all one thing how would i do that

[sage patio]

use an emission mask

a mask is just a black and white (or with gray-scale) texture

where there's black, no glow

where there's white, it'll glow

[gentle veldt]

not sure if this is the correct channel but....
anyone know why my cats blender plugin is misbehaving? it is up to date i already checked

[gusty flint]

I found a model I want rigged for VRC

https://sketchfab.com/3d-models/johnny-the-homicidal-maniac-final-8816f368cfd841948f2f02b3a32cb801

[crisp tendon]

https://ask.vrchat.com/c/commissions/avatar-commissions/35

[sharp gyro]

Something I've noticed, that I'm sure is probably known to most people here, is that some avatars have different 'animation templates' on desktop. Not just moving differently due to different proportions, but different postures as well. Many humanoid avatars I've used have a crawling animation that makes them look like they're supposed to be holding a rifle, while others do not, some crouch with the hands in different positions, etc. What's the deal with that? This is something you can choose when you create the avatar, right?

[fading verge]

Yes, you can change your avatars animations in unity

Dont really remember how though, havent modeled much in 3.0

[opal dome]

im getting a vroid custom model commissioned rn and wanted to get it rigged for vrchat once its complete but its been so hard to find commissions for it and then i remembered i was in this server

[shrewd flame]

Hello! Sorry if this isnt the right place to ask but I've been screaming at my PC trying to get this avatar to work, when I look up or down the whole model moves with the head making it crouch when looking up and go on really high tip toes when looking down, It also walks around a bit when looking to the sides, I googles a little and saw one person say it might be due to where the VRC Avatar Descriptor is placed but ive tried moving it around and its still the same, any advice?

[leaden ledge]

hai, can someone help me with a model issue? im not sure where to talk about this... its when i do blendshapes in anim files.

i think the face part of the mesh is clipping thru, why is that?

[leaden ledge]

sounds like ur view point might be off? also sounds like you might need to redo your rig

[shrewd flame]

Its weird, It looks like everything works completely fine in the muscles & setting preview, yeah ill have a look at the rig again :[

[rose wagon]

Gun crouch was the default laying/prone idle for older sdk2 avatars

You can change it if you want.
And 3.0 let's you have multiple different prone idles if you so choose. Sdk2 was limited to one for both PC and desktop

[sharp gyro]

Neat, thanks!

I'm still quite new to this game, how are different animations toggled? I've discovered the rotary menu that pops up when you press R, but is there a way to bind animations to specific keys?

[sage patio]

you can't assign things to different keys. keep in mind this is VRChat. if you do Shift + F1 through F8, you can emulate a VR user doing a certain hand gesture. using left shift will control the left hand, right shift the right hand.

the gesture you're doing can then be used to trigger certain animations

if you want to add things to the menu, you can do that too

so that you can hit R, and select a thing in the menu to do something

[sharp gyro]

Can keys be remapped at all?

[sage patio]

stop posting that shit in every channel

[sage patio]

somewhat, there should be a key bindings section in the VRChat settings menu

[fading verge]

I've given up on this avatar, but i'd like to know for future reference, i used VRoid to create an avatar and then put it into blender, when i try to create eye tracking, it says that the bones need to be in a specific order. This is easy enough, but there is an extra bone parenting the neck which i could not get rid of, meaning there was an extra bone preventing it from being in that order. The bone was "upper chest". Sorry if this is not the right place for this.

[sage patio]

you don't need to "create eye tracking", the model already has eye bones, and that is all you need

[fading verge]

oh, i was watching a tutorial

[sage patio]

UpperChest is actually a good bone to have with the new IK, you should keep it

[fading verge]

ah

ok

[sage patio]

what date was that tutorial uploaded?

[fading verge]

uhhh

lemme check

Feb 18 2022

[sage patio]

wow alright

was expecting it to be super old

[fading verge]

yeah lol, i might have been misunderstanding some of it but idk

[sage patio]

the eye tracking setup is done in Unity. you basically just specify the eye bones in the Avatar descriptor, and specify the maximum rotation of said bones

[fading verge]

Ah

It was using some CATS blender plug-in or something I think that I tried to do it with

[sharp gyro]

Can the rigging and texturing process be done in unity? Blender is just so frustrating to work with, I'd rather make the raw geometry in something like solidworks, and take my chances learning to do everything else in something unfamiliar like unity

[sage patio]

no, Unity is a game engine, not a 3D modeling program

Solidworks is a CAD program, it's not for polygon modeling for games

Blender isn't the only option, but it's the most popular one, and the one you'll be able to get the most help for

the learning curve of blender is steep, but it's important to have patience and perseverance

for texturing, blender is actually not the best option

Substance painter is a much better solution

[sharp gyro]

Solidworks can export STL, which other 3d modelling programs can work with, I've done it a handful of times, being able to export the parts at varying polygon amounts is nice. Was hoping to use that as a shortcut, since I have a lot more experience with solidworks than anything else

oh well hahaha

[sage patio]

converting CAD into STL will result in an extremely bad model, topology wise

that will make it extremely hard to nicely UV unwrap for texturing, and weight paint for rigging

if you want, you can make your base model in SW, export as STL, and then use blender to do a "retopology"

where you essentially construct a new mesh on top of the original high poly version

using tools like the Shrinkwrap modifier

[sharp gyro]

I was actually planning on doing something like that manually with sketchup... that's probably just sounding like increasingly dumb excuses not to use blender!

[sage patio]

Sketchup is not meant for this kind of work at all

I would recommend just biting the bullet and learning blender. trust me, it'll take a while, but it's well worth it

[sharp gyro]

I used to use it to clean up stls for 3d printing

but yeah you're probably right

i'm getting these two "errors"

however, the upper arms ARE specified

and so is the head.

..heelp

(these haven't produced errors in the control panel, so don't worry about them)

[fading verge]

Hey, new to blender. Any idea how i can access the bones to edit, it's not letting me and just howing seethjrough

do i make the head bone parent of hair?

[ornate cairn]

can you show whole hierarchy?

[graceful mulch]

@ornate cairn

[ornate cairn]

hair doesn't need to be parented to body

[graceful mulch]

well what needs to happen?

[ornate cairn]

can you click on hair mesh go to blue wrench

add modifier that is called armature

[ornate cairn]

add armature modifier and in object add your rig

ur on wrong thing

you need to be on orange triangle

[ornate cairn]

that is not the right tab.

[graceful mulch]

what tab??

[ornate cairn]

ur in bone constarints not modifiers

[graceful mulch]

where's that??

[ornate cairn]

click on orange triangle on top when holding ctr

how do i connect bones to a model

[deft zealot]

is there a list of necessary things along the lines of like

what i should be doing to make an avatar fully FBT compatible

[sage patio]

follow the standard rig, and make sure it's proportioned well

would also recommend having an Upperchest bone

[deft zealot]

this doesn't even have an upper chest is there a reference that has one

[rose mountain]

When using elbow trackers... Do the trackers attach to the Arm or ForeArm? Simular question for knee tracking.

[sage patio]

upper arm (so the shoulder movement works properly), as for knees I prefer them above the knee so I can kneel

I put the knee trackers off to the side a bit so I can also cross my legs

[rose mountain]

Thx. Gearing up to do some IK experiments.

[dapper moon]

Hi, I’m a bit new to 3D in general. I just wondered if anyone knew how to rig a 2D face for an avatar, most of the tutorials I found aren’t for real-time like VRChat

[void canyon]

to rig 2d visemes?

[dapper moon]

Yeah, basically

[void canyon]

you'd do it with sprites rather than traditional moving the face with blendshapes

[dapper moon]

Static eyes that stare into your soul is not a super good avatar design as I found out

[dapper moon]

Technically a new texture every time?

[void canyon]

like creating bits of textured mesh hidden inside of the face, that surface just above the existing face mesh when you activate the blendshape

[dapper moon]

Or do I have to do face sprites that’s separate from the texture?

Hmmm

[void canyon]

https://www.youtube.com/watch?v=ZB2aXKkwXuA

[dapper moon]

Got that

[void canyon]

very old tutorial

but this is basically the idea

[dapper moon]

As long as the concept is the same

[void canyon]

not sure how well eye movement would work w/ a 2d face though

blinking should work fine

[dapper moon]

Nah, I just want blinking and expressions

[void canyon]

bling 💰 💎 yo

[dapper moon]

The hotline bling

[void canyon]

😆

[dapper moon]

I wonder how well this will work because my uv seams are pretty meh so the texture map is just messed up

[fading verge]

question regarding rigging as I've forgotten a few things

does the whole arm have to be attached to the shouder

shoulder**

[dapper moon]

no

[fading verge]

alright

thanks

[ornate cairn]

if you mean connected than no, it can keep offset

[quick cape]

does anyone have a working example of a Generic rig with any animations applied? the documentation claims that one is included with the SDK3 but i can't find it

[void canyon]

most people just make a separate texture with the various expressions stacked together

[dapper moon]

yep, but doesn't that make it less optimized?

also

[void canyon]

why? you can always atlas it

[dapper moon]

fbx files don't store the animation, right?

so I have to import the Blender file

[robust crescent]

fbx can have animations in em

[ornate cairn]

you can export fbx with animation in it from blender

[dapper moon]

ah yeah, I see, it's just exporting it without for me

but this is a me problem

[dapper moon]

ok

how do I export the animations now?

[ornate cairn]

do you have bake animation selected when exporting?

[dapper moon]

yep yep

it just gives me 3 animations in fbx viewer

and they're all 0 frame

do I actually do it in action or shape key editor?

I've tried both

[ornate cairn]

hmm the fbx you imported with animations set as humanoid

[dapper moon]

well it's definitely all there

at least I think so

[dapper moon]

is this a question?

[ornate cairn]

hm yes did you set avatar as humanoid after it being imported

[dapper moon]

yes

I mean, the animation is just broken

[ornate cairn]

did you set apply scallings to fbx units scale?

on export

[dapper moon]

I think???

[ornate cairn]

nope it's all local

[dapper moon]

oh I see

still the same thing tho

[ornate cairn]

wdym same thing you just screenshooted animation file

[dapper moon]

I meant the length

it's literally 0 frame

[ornate cairn]

you need to put it on controller and controller on animator

that's how you test it

[dapper moon]

it's not there

[ornate cairn]

bcs it isn't blendshape but animation .

[dapper moon]

ok sec

I'm confusing stuff

working with me is a hard task because I'm quite new, hope you understand

[ornate cairn]

now i know what you wanted.

you wanted to make blendshape

but you made animation.

you can use it for blinking tho.

but that would need set up in controller

you need to do more research on blendshapes

in blender they are called shape keys.

[dapper moon]

let's say I made 1 for blinking

can I just export fbx and have it work in Unity?

[ornate cairn]

yes,

watch some tutorials on them to not be confused .

[dapper moon]

well the shape keys are definitely not exporting for me

ok, if I have any questions, I'll ask

thanks a lot for your help

[ornate cairn]

you can check all your blendshapes when you put avatar on scene and click it's body mesh on hierarchy

still watch tutorials on them.

[dapper moon]

question

this counts as an animation, right?

if it's created in the shape key editor

[ornate cairn]

yes it is animation.

[sage patio]

not sure why you're trying to make an animation at all

literally all you need is the shape key

and you specify it in the avatar descriptor

vrchat handles the blinking for you

[robust crescent]

Never used those myself , always an anim i can easy disable and make it blink randomly, other feels too static

[dapper moon]

it doesn't show up for me

why the shape keys/blendshapes don't show up for me in Unity

[warm pendant]

make sure Apply Modifiers is unchecked when exporting the fbx

[sage patio]

check if any of your meshes have modifiers (excluding Armature modifier) such as Shrinkwrap or others. modifiers are a blender exclusive thing, so it can do one of two things when you export:

• remove modifiers, and keep shape keys
• remove shape keys, and apply modifiers

applying modifiers to meshes with shape keys cannot be done with vanilla Blender. every shape is a different arrangement of a mesh, and can technically be considered a separate mesh. there's an addon called "ApplyModifierForMeshWithShapeKeys" (very fitting, I know) that allows you to do just that, by duplicating the mesh for every shape key you have, applies the modifier to each one, and then joins them all back as shapes.

(note: some modifiers like Armature and Weighed Normal can be applied even if a mesh has shape keys)

[dapper moon]

thanks

it's working now

thanks a lot, everyone, for the help

[vital veldt]

is it possible to make Pistons move when moving in avatar? I'm wondering if I can make a Terminator avatar and the pistons move when moving wrist or clenches fist? it has bones on the pistons

[glass panther]

For vrchat's elbows is the ideal position having it bent slightly back instead of having the upperarm and lowerarm completely straight?

[crisp tendon]

Should try asking in #ik-2 since that behavior might change soon !

[vital veldt]

So is it possible to increase and decreased the piston bones to the act like real pumps and if so how does one do that?

[robust crescent]

Blendshape or bone change when fist / emotes / ect, constraint when moving arm , never tried it

[vital veldt]

how about natural movement, raising arm, bending elbow, Valve index Finger tracking? or am I being too adventurous.

[ornate cairn]

that needs much work with ik

but it is doable

[glass panther]

TY!

[lunar mango]

Any help I try making the atlas for my new quest avatar and it breaks my textures

[fair plank]

Make sure every material is using Principled BSDF first

[gilded ibex]

also make sure the texture path is defined and readable, not in the blender temp folder

[gleaming swift]

Does anyone know how to fix this? In full body the right leg sinks into the ground and the hip gets goofed.

[crisp tendon]

What does the armature look like in blender ?

[gleaming swift]

plantigrade bones arent weighted to anything

even when i use the legs regularly i get the same thing

[robust crescent]

Hip might be tilted/too low

[blazing iris]

Yea, pistons actually work pretty well with constraints but one problem is i dont think constraints are available for quest

You're gonna need two constraints for each piston tho

and a bone for both the extension and base part

If you're looking to do individual pistons for each finger, thats gonna be a lot of constraints

and you also need to have enough pistons and rotation points to cover all the degrees of freedom needed for the body part

to avoid weird clipping

[blazing iris]

you might be able to use blend shapes as well and that'd work on quest

but im not sure how you'd align the pistons and i havent experimented with that

[sage patio]

how would you actually activate those blendshapes lol

can't really do that

[blazing iris]

yea thats why i went for constraints

[sage patio]

only way I can see this sort of working on quest is using clever bone rigging

let me try to set up an example sort of

no idea if it'll work

[blazing iris]

you mean like weight painting nstuff?

[sage patio]

ye

[blazing iris]

id think theyd look kinda bendy

idk tho

[sage patio]

if the pistons have no extra loops in the entire length except for the ends, it can't bend

[blazing iris]

ohhh yea true

smart

[sage patio]

@blazing iris

[blazing iris]

oh wow

that works pretty well

im starting to regret investing in constraints

[sage patio]

my method will work well until it starts twisting the other way lol

the way you did it is by far the best

just a shame it won't work on quest

[blazing iris]

u could have like rotating bits to avoid twisting

oh but then you'd need a rotation constraint

[sage patio]

kek

in unity, you can actually edit the maximum rotation of bones in the rig config

in the Muscles and settings tab

so for example, you could set the Lower arm twist to a very small value

default is 0.5, so maybe like 0.05

[blazing iris]

ooo

ive never looked at this tab

[void wren]

loving the pointers here.

is there a youTube vid that maybe concentrates on this type of rigging?

[sage patio]

you mean like rigging robots/mechanical models?

[void wren]

right.

[sage patio]

I'm certain it exists, just haven't looked for one

[void wren]

It is easy enough to download the assets and make modifications, I just don't know how to animate

[sage patio]

there's no animation involved

it's just rigging + adding constraints in unity

[void wren]

right... rigging for motion right?

[sage patio]

pretty much I guess

you basically have the standard humanoid bones like the upper arm, lower arm and wrist, then add extra bones for different mechanical parts

like pistons, plating

then use constraints on those to make them follow the movement of other bones the way you want

[void wren]

thanks! I will be playing with this tonight

[sage patio]

also, when you're doing mechanical stuff, it's not often that you will have "weight gradients", since things aren't supposed to bend

so when "weight painting", it's going to be more like just assigning a bunch of selected vertices to one particular group

you can do that in Edit mode by just going to the vertex groups list

or in weight painting mode by selecting vertices and doing shift + K to assign a weight to all of those vertices

[void wren]

I think I remember some of weight painting from building my donut!

[sage patio]

"weight painting" is just mass-assigning vertices into vertex groups using brushes

[void wren]

right, everything is an abstraction

[gleaming swift]

I checked and no matter what it's still doing the same thing

[robust crescent]

hip look anything like that ?

[gleaming swift]

https://i.imgur.com/HxwhHZP.png

[sage patio]

not like that, in the viewport

[gleaming swift]

https://i.imgur.com/kUY5jaO.png

https://i.imgur.com/9CLn9Yf.png

[sage patio]

oh yea no that will never work well lol

no matter how the avatar is rigged, it still has to conform to a normal humanoid armature. it's possible to rig digitigrade legs like that, but you still need an underlying humanoid frame

[gleaming swift]

[gleaming swift]

ive used this with other avatars and its worked fine

[sage patio]

oh so you did do it right in this pic

[gleaming swift]

yeah it was just hidden by accident

[sage patio]

try resetting all of the bone rolls

select all bones in edit mode, then go to Bone > Roll > Clear roll

[gleaming swift]

I'll give it a shot when i get home from work

If the bones were rolled wouldn't it affect when not using full body tracking?

[vital veldt]

Yeah that's the type of movement I'm after for my Terminator, how does one assign constraints in Unity? if there a video of tutorial?

[blazing iris]

All you really need to do is have two aim constraints pointed at each other. Haven’t actually found a tutorial, just sorta experimented myself

Constraints can be added as components

[brazen cosmos]

so the builder is saying i dont have hands, head or feet mapped but the rig has it mapped. idk what thats about

[blazing iris]

to each bone

[blazing iris]

It’s probably in the fbx settings, sometimes if the naming conventions aren’t exact Unity doesn’t assign bones to certain parts of the humanoid rig

[brazen cosmos]

well

it only said it after i had already built and published

[blazing iris]

Ohh

[sage patio]

have you ever unpacked your avatar in the scene?

if so, that's bad

[gleaming swift]

Yeah i had a similar thing happen when i unpacked the prefab and modified some bones i didn't need

[brazen cosmos]

i unpacked then published. didnt change anything at all

[sage patio]

that's something you should be doing in blender, not unity

never unpack avatars

[sage patio]

drag the FBX into your scene again (don't unpack it), and use Pumkin's avatar tools to copy the stuff from the old avatar to the new one

like the avatar descriptor, dynamic bones, etc

[brazen cosmos]

i dont have that tool

[sage patio]

https://github.com/rurre/PumkinsAvatarTools/releases/tag/0.9.6

[brazen cosmos]

now its different, cool

[sage patio]

you have too many spine bones

or wait, hm

yea you do

one too many

[brazen cosmos]

I used the cats plugin tho, that must not be perfect

[sage patio]

CATS is not magic

you still need to know what you're doing

"Fix model" is not a genie button

CATS does have tools to allow you to merge bones and their associated weights to other bones though

which is probably what you want to do here

[quiet gazelle]

Do I need shoulder bones for VRC, or can I go without them?

[ornate cairn]

you need them

[quiet gazelle]

Alright, good to know. Is there a list of required bones?

[sage patio]

all these minus toes and fingers

[quiet gazelle]

Aight. Is this an alright position for the shoulder bone? I mostly just want to make sure that the arm won't clip into the side of the body too much when I'm in a resting position, or something

[solemn sail]

Hey so im having an issue with my avatar's Eye. For some reason, one of the eyes flips backwards 180 while animating in unity, and in game it spins and flips all over the place, but only on my local view, network view it works fine, no issues. I'm assuming it's a rig thing but if i should be in another channel please send me elsewhere lol

[crisp tendon]

Screenshots of unity/blender ?

[solemn sail]

Normal > Animating > Blender

[sage patio]

select the bones, and do Bone > Roll > Clear roll

[solemn sail]

didnt seem to do anything visually and roll was at 0 already but ill see if that changed anything on reimport

yeah still flipping in unity

[sage patio]

alright. click on your FBX, go to the Rig tab in the inspector, and click Configure

at the bottom, click Pose > Reset pose

then Apply, then Done

[solemn sail]

okay, seems to have stopped flipping, lemme try in vrc. Thank you for the help

[sage patio]

👍

[solemn sail]

yep, working perfectly now. Thank you so much this has been plaguing me forever lmao

[sage patio]

nice, glad to hear it works fine now

[quiet gazelle]

Do I need finger bones if I wanna use the avatar with full body tracking?

[sage patio]

hmm, you might

try adding thumb, index and middle fingers

[quiet gazelle]

Does it need all three joints/knuckles on the fingers?

[sage patio]

I don't think so, you can try starting with a single bone for each finger

I know that two will work

but try one for now

[quiet gazelle]

Is it fine if I'm lazy with the bones and just extrude 'em like this?

[crisp tendon]

Yeah that's alright

[quiet gazelle]

Alright cool, thanks

[hasty reef]

Anyone know where I can find a hog rider or other coc/clash royale avatars? (For the memes

[gilded ibex]

beside this one, anyone knows any world that can visualize how avatar bones moves, much like the visual of blender in pose mode?

[winged escarp]

anyone know how to make a humanoid rig?

[winged escarp]

nvm

[narrow heath]

So um…i config. the bones in unity since the avatar was in tpose in vrchat and this happened…help.

The both arms and neck are messed up…

[sleek isle]

FBT caliper

[vital veldt]

How does one fix this issue? I'm trying to rework the elbow so it bends more naturally but I can't seem to fix it.

[worldly hull]

My mic is functioning and mouth viseme sliders are affecting mouth movements in Unity, but not in VRC, it works through other people's eyes but i don't see lipsync in a mirror. And after looking at the old version that works and the new version that doesn't, I've noticed that the old version has some visemes in bold, whereas the new version doesn't have any bold 0's,, I'm looking into what causes the boldness .~. but I hardly know where to start right now

[worldly hull]

i think at some point i right clicked blendshapes and clicked revert, i dont know how to undo that, PS i solved this, other people could see mouth movement but i couldnt in a mirror, this is because i attached a cape to the armature of the avatar instead of elsewhere. pps i added it back to the armature with names like spyne, hyps, armyture,, and the cape + lipsync are working now i also messed with the cape's anchor / root bone

[daring osprey]

anyone know how i can fix this

in blender

in unity

i have asked in avatar 3 help yesterday but nothing really worked

[sage patio]

in unity, go to your rig configuration, and click Reset pose in the bottom right

[daring osprey]

pfft that worked thats annoying but thank you so much😂

[carmine knot]

does anyone know why the builder menu disappears? I reimported it but still nothing

[hallow lance]

Can someone help me out with this? I just got to the step of bringing in the up-to-date SDK and .fbx blender model and its giving me errors right out of the gate with Unity. The hand one I kinda understand, but if it involves going back to Blender and reworking the model to have a "hand" in the bones I'll probably need help with that too.

[ornate cairn]

usually happens when you have wrong unity version.

the error above

[hallow lance]

I just reinstalled unity like a couple hours ago? is the current SDK not tuned for the latest version or something?

[ornate cairn]

latest for sdk is 2019.4.31f1

not latest version of unity

[hallow lance]

Ah. So I have to see about getting THAT then...

Any idea on the 2nd thing, for if I'll have to backtrack to blender or not? It's a Voidoll avatar, so it doesn't have explicit "hands", but it does have little dots for "fingertips" I guess.

[hallow lance]

also im looking in the unity hub for that version and the closest thing to it is this one, is this good or does it have to be SPECIFICALLY that version.

[ornate cairn]

did you checked config tab?

also no

you need 31f1

https://unity3d.com/unity/whats-new/2019.4.31

[hallow lance]

what config tab?

[ornate cairn]

rig config tab

[hallow lance]

like what pops up on the right when its selected?

[ornate cairn]

click on fbx go to rig and configure button

[hallow lance]

if it's this thing then yeah that's what giving the error to me, or sounding it out.

[knotty drift]

wait nvm, discord was way behind on messages

[ornate cairn]

you probably gonna need to fix it in blender

[hallow lance]

so I'll need to somehow rig a hand for a handless avatar XD

for ref of what I mean

[ornate cairn]

you can add hand bone but not weight it

[hallow lance]

how would I do that? I'll be honest I'm very new when it comes to this again. Dabbled a bit back like 3-5 years ago but everything's changed and I've forgot XD

[ornate cairn]

Literally extrude the hands bone from lower arms name it so you gonna know which one is it and ur done unity won't scream again

you won't even need to do anything more

[hallow lance]

ok one moment.

btw that was the right version of Unity you linked me right?

[ornate cairn]

yes

download android support from there also

[hallow lance]

these two right?

[ornate cairn]

yes

[hallow lance]

also looking at the bones again I have hands by the looks of it. maybe they're not properly identified?

[ornate cairn]

are they parented to lower arms?

[hallow lance]

Here let me show what I just found in the armature

so it gets to the arm and then goes arm>elbow>wrist in that order for the 3 bones there.

[ornate cairn]

what if you config rig in unity

does it see the wrists

which act as hands

[hallow lance]

I didn't hit that button actually.

I hit apply

let me try hitting that one

ok this is a completely new interface to me.

[ornate cairn]

on left you have the bone hierarchy

you need to assign chest and shoulders and hands

you can click the white circle on right or drag from left panel to None
