FIXES AND UPDATES: Just use the correct version of Blender and everything should work. I was on v2.93 To everyone having issues with the textures turning into one color (one texture) when create a material atlas (in Blender), try using the same version of the VRM Add On that I use in this video (2.1.11). OR before doing the atlas you can unpack the files by going to File > External Data > Unpack all files (Thanks tucker in the comments for finding this). If you're having issues (like with eye tracking), then before hitting Fix Model, click the wrench and disable "Keep Upper Chest." Then continue to edit the model as usual (not sure if this breaks something later on, but someone said it worked for them). If you're having issues installing the material combiner plugin, make sure you downloaded the correct files. On the download page it explicitly says to download NOT from the assets section, but from a link in the CHANGES description. For a lot of issues, make sure you're on the right version of blender and start over with a brand new project. Make sure you're following the tutorial EXACTLY. Sometimes bugs just happen and you need to go back a few steps and make sure you didn't do anything wrong. For more help, join my Discord: discord.gg/zNGW6pMPZb

[@ModestNeko]

Fixed a problem. If your avatar imports into Blender fully colored and when you click "Fix Avatar", the eyes turn white, just do the wrench and uncheck "Combine Same Materials". This should fix that problem (and hopefully not cause others). Also make sure you're using BELOW version 2.16 of VRM cuz 2.16+ is not compatible with the material combiner and causes all sorts of issues with atlasing.

[@P4P0W]

THANK YOU!

[@kachow08ify]

So any ideas on what to do if it doesn't fix it? if you don't know it's alright i'll figure something out

[@ModestNeko]

@@kachow08ify No idea as that ended up working for me. Sorry. Though oddly enough, with another VRoid model, I didn't have this problem. Not sure what the difference was. Best of luck getting it to work!

Also if you need to reduce more polygons you can remove some of the skin under the hoodie and pants by deleting the vertices. You would not need it anyways on a quest avatar

[@mercurymoon16]

this is amazing

[@Its_A_Gundam]

3:53 for anyone else who got the following error: Eye tracking will not work unless the bone hierarchy is exactly as following: Hips > Spine > Chest > Neck > Head Furthermore the mesh containing the eyes has to be called "Body" and the armature "Armature". If you were also unable to solve by repeatedly clicking, I was able to fix it by creating the Neck's parent bone to the chest. For some reason it was set to upper chest.

[@michig3931]

I'm Waiting For part 3 and get well soon

[@RakeHipster]

Guys to anyone whos following this tutorial; The Github download for the material addon has a different download link, just make sure to read the creators note above the versions. There the link will direct you to the new version

[@sebastianren268]

how do u install add cats plugin in blender, i tried the source zip and the blender version but it didnt add into the add ons

[@whompthwompyy704]

Part 3 plz!! 🥺🥺🥺

[@NezLikesGames]

yo my eye tracking thing says neck and chest bone arent connected how do i fix that

[@evievrc]

Try going onto editor and click the neck bone, then click the bone image on the right of your screen and it should say neck, and you should see a thing called relations, your gonna wanna click on that, and if it says the bone is parented to upper chest, your gonna need to change that to chest. Hopefully this wasn't too confusing and helped lol

[@lunarubyeclipseWLRE]

Issue that I ran into that I was able to figure out: When you go to Atlas, it may say "Install Pillow". Go ahead and install, then restart blender. If it still just shows "Install Pillow", just hit that again, restart again, and the option to generate materials should be there!

[@MorbyLol]

should i be deleting dynamic bones if im using this on quest after the avatar dynamics update?

[@shaderickard3606]

I combined the textures using atlas and tried manual but im still getting a error message that it has 11 materials when it should have 1

[@missmelancholy7860]

sadly my blend shapes didn't go over to unity and i have no idea why. this has been an amazing tutorial though!

[@kings_bane1221]

Hey Panda, I cannot seem to install the add on files, any tips?

[@flooraax]

I have a problem, when i do the quest optimization of Altas Materials it say that i need to download the material combiner because it isn't installed, how can i solve it? Anyways good video! I also can't enable the material combiner add-ons

[@itsd33z11]

When you get rid of the movement in the hair does that make the hair stiff or does it still floe

[@Ateldd]

Hey y'all! If you have already changed to an older version of VRM and the Material Combiner still isn't working, try using a slightly older version of the material combiner. That fixed my issues!

[@lunarubyeclipseWLRE]

Thank you so much!!! That fixed my issues!

[@OSAlula]

Just wondering as I'm not entirely sure, is the Eye Tracking and Visemes steps required?

Anyone having issues with atlasing textures? Try unpacking your .blender file! File > External Data > Unpack All Into Files

[@lavenos3407]

hello if anybody is having problem witch merging all textures together you need to downgrade your VRM to version 2.15.26 and downland material combiner addon dev build and remember save Vroid avatar to 0.0 not 1.0

[@Hoshi82]

Where do I get the material combiner addon dev build? In Blender it only lets me select the regular versions.

[@blyxon_vr6659]

when i try to enable the material combiner in the blender preferences it won't let me

[@Spirit0fBoredom]

if my model has a tail should i attach it in unity first and then fix it in blender?

[@Hunter248GM]

great video! although for me the mirror mode doesn't work, and the material combiner keeps generating problems, basicly it does all the textures wrong within the atlas

[@baconrap3850]

Can't quest have dynamic bones now?

[@astrangerontheinternet6901]

I'm able to resize my model in blender yeah? follow up question if I can how small can I be???

[@hehotbros01]

Are we supposed to combine mesh? I mustve missed that part but i says i have to do it before export?

[@walluby1640]

if the material combiner addon gets an error enabling just get a older version

[@Bat.of.the.graveyard]

why cant u have dynamic bones in hair for quest? is in anyways that optional? or will i mess my avi up?

[@TheUnrider]

My experience with this tutorial: At the fix model section I had to disable combine smae materials sin the settings just right to it so my eyes didnt disappear. And at the atles section I had to install something that disabled the plugins installed before, that confused me for a minute there.

[@GoofyMan-7]

my avatar is fully pink exept the hair how do i fix that ?

[@RamenIsSuper]

for some reason whenever I extract the textures it doesnt wanna put any textures any way to solve this?

[@kathrinecatgirl935]

What if I want to decimate the face of my model; will it still be able to have face expressions/animations? All this reducing polygons section made me realize I can actually make a low polygon version of my model by myself to give it the PS1 dimension feel.

[@ModestNeko]

I still have to test this but when looking it up, it appears that there's one optimization fix that brings the polygons down MASSIVELY. Select your body armerture, go to edit mode, click and drag to select all of your model then in the "Face" menu, click "Tris to Quads"
