Ninth part of my VRoid tutorials. This time the we're continuing from where we left in part 8, and getting into hiding the accessories and showing them with blendshapes
Make sure to check the previous tutorial on how to import accessories to your VRM model:

Thank you so much for everything you do for the community Suvi. You've made vtubing accessible to so many, you're truly a beacon of positivity and a lot of us would be lost without you. Much love

[@rutrine]

thank you so hecking much for making this tutorial!!! i spent forever trying to fix the sunglasses prefab i made........... i didnt realize you had to change it to cutout D:

[@Suvidriel]

Glad it helped~

[@alwaysyouramanda]

I cannot thank you enough for these! I'm having so.much.fun! I love how challenging these can be, but you cover everything so perfectly! Suvi, you're the best! I wish you all the happiness and success there is to be had!

[@petroleumtaco]

Omg Idk how i didn't see this earlier cause I've been making new models for each prop. Thank you so much 😅😅

[@은섬이다]

Thanks! It works in 2024

[@Suvidriel]

Yea it still should work but is not very optimal way. Best is to use vtubing app like VNyan that supports props

[@anubisrage2397]

thanks

[@YOKERMEISTER]

In Blendshapes, i can't see in the material list a material I just added, any help? Thanks for the video :D

[@yourmimic1184]

even when importing a prefab i made of a single object, it wont show up in the material list. when showing the folder its in. its not even the right file. instead of asset it's some random file type with no meta data added to it

[@cocolf]

3:02 I don't know why but the materials do not appear in the list when I add it in blendshapes

[@Suvidriel]

This happens when you add the accessories to your model in scene tree instead of clicking the "Open Prefab" and adding the meshes there. Blendhsapes use the prefab - not the scene tree-version.

[@ClobyPlay]

I'm having the same error. But the problem is that I doble checked if i imported everything in PREFAB, and the texture is still missing

[@Suvidriel]

@@ClobyPlay Ok sounds a bit odd. Maybe try exporting the model with the imported assets, reimport to a new project, fix the missing materials if any and see if it shows up then

[@Caelem]

@Suvidriel is there a way you can make new materials (that aren't already on a mesh) that you want to apply to future meshes, and make them show up in the blendshape options?

[@Suvidriel]

You can create new materials but the materials need to be assigned to meshes to show up in the blendshape options. The unassigned materials will not be exported with the vrm model.

[@itskiggu]

Thank you for this tutorial! Is it possible to use new blendshapes that can be added as hotkeys in vseeface so we don't have to use default expressions to show/hide objects?

[@Suvidriel]

yes and that's how you should do it. You can bind them to hotkeys in vseeface's expression-settings

[@itskiggu]

@@Suvidriel Thank you so much! I didn't realize you could bind expressions that weren't the "defaults", this opens a whole new world!!

[@nox_rayne]

I've tried and I'm still having difficulty :/

[@me_dyrl]

Is there any tutorial on how to trigger the additional made blendshape.clip in vseeface to make the object appear? I have added an additional blendshape.clip but i didn't see it in vseeface aside the 6 default expression.

[@Suvidriel]

You can add blendshape clips to hotkeys in the expression-settings. If your blendshape doesn't appear in the list then I recommend you re-import your model to Unity and make sure the clip actually exists

[@CoisasdaLuisaHelena]

Is it possible to do the same thing but In blender? :)

[@TheMethodus]

I appreciate the tutorial! I do have a question though. I unpacked prefab, added my prop to the model (in this case it goes to the right index finger) and when exporting as a VRM and loading into VSeeface, it states that there is no longer a VRM Blend Shape Proxy or Blend Shape Avatar assigned. And now the model has no face movements. Any idea what could have gone wrong?

[@Suvidriel]

It sounds like the blendshape avatar got reseted somehow. The blendshape-avatar is basically the blendshape index. If you select your model in Unity it should in inspector have a field for the blendshape avatar. To that you need to assign the blendshape-index (File called Blendshape) from the blendshapes folder

[@TheMethodus]

@@Suvidriel Yeah I saw that, looked like it assigned. There was a lot of blendshape details in the folder. I'll double check when off work. Thank you for the assistance! Your tutorials are a HUGE help with this whole process!

[@WatchingLizard]

how do i get prefab ???

[@Suvidriel]

What do you mean? Like where to get accessories or how to add them to your vrm model? The part 8 of my tutorials covers the addition of accessories to vrm model

[@WatchingLizard]

@@Suvidriel I don't see the prefab option

[@Suvidriel]

@@WatchingLizard ahh you mean the "Open Prefab"-button? It should show when you select the vrm model. Make sure you have the latest Unity and UniVRM installed

[@PlumcakesGames]

No matter what I try, I can't get the sounds to work :( It works in Unity, but when I put it into VSeeFace, it just refuses to play any audio.

[@Suvidriel]

Are you exporting it as VSeeFace avatar bundle instead of vrm?

[@PlumcakesGames]

@@Suvidriel I did, but sadly, nothing. I messed around with some settings and now I can't even get the vsfavatar file to run in VSeeFace. I think I may just give up :( But I appreciate the quick response! Your videos have been a HUGE help!

[@KuroechiCH]

does this method work for clothes too... so 1 character 3 clothes ???

[@Suvidriel]

Not really. If you want to swap clothes then a lot will depend on the kind of armature the clothes are using. If they all share the same armature then it's very close to this but if not then you might run into issues. If you were to model all clothes on top of each other in blender then yes, you could use this technique. If all your clothes are using same model - just different texture then that would be the easiest and you could just swap texture coordinates

[@KuroechiCH]

@@Suvidriel not using blender,..can it use vroid for costume???

[@Suvidriel]

@@KuroechiCH Sadly you'd need blender to merge the different meshes since vroid uses different armatures for the models.
