This is now a second draft. Much of the items here I've had a chance to actually test and trial out in CVR.

With the right tools the conversion process is relatively painless, most of the hassle I had to fight with is having a fragile unity project.

Conversion Process

Resources

This section contains links to tools or whatnot you will likely find useful.

CVR dev kit (CCK)

VRC to CVR conversion tools:

Physbone Conversion:

Other Related Guides

tl ; dr

  • Copy project
  • Convert physbones back to dynamic bones
  • Install CCK (CVR dev sdk)
  • Run a conversion tool on your avatar
  • Delete VRC components on avatar
  • Upload to CVR (Tag honestly)

Starting out

In my testing I started with a pair of VRC projects. One was simple and contained a basic kikyo, and the other was horribly big and buggy containing my actual avatars. I managed to get both converted.

FAQ:

If you have any questions and get them answered please add them here, it's a wiki!

  • Do I need to remove the VRC SDK and stuff? I didn't remove all VRC shit from my old project. VRC stuff mostly doesn't break anything but large projects can be fragile when copied regardless. There's one script that should be removed (see later in the article)
  • Does my <insert shader here> work? All your shaders and stuff will work. That includes DPS.
  • Toggles and sliders and stuff? The fluff converter will preserve your toggles, sliders, submenu toggles and even your custom gestures (like from CGE).
  • Do I need to publish to use my avatar? Publishing is for when you want your avatar to be public. If you just want to use it for yourself there's no need. In addition, you can share your avatar without publishing with specific people on a whitelist basis.

Create an Account

  • Make an account on their website ( https://hub.abinteractive.net/ ) , download the CCK (their SDK) (https://developers.abinteractive.net/cck/setup/). Or use the account you made a while ago that you reserved your username with. Right?
  • Make an API key on the hub (Home -> access key manager) and copy that and keep it somewhere safe, it's basically a password to all the content on your account.

From Existing project

Goal number 1 is to produce a stable project from your existing work.

You basically have two options: Use a copy of your entire existing project, or import pieces in to a newer, fresher project. What I recommend depends on how big your existing project is. For huge projects you will want to pull pieces out, but for small ones a whole copy will be perfectly fine.

You can work on your existing project without copying, but having backups of 'known working project' is highly recommended. If you 7zip compress copies they take up a lot less space.

The importing pieces section looks way longer but it's still quicker for large projects. Especially if you mess something up and have to restore from a backup.

Full Copy

  • Find the location on disk where your project is, and copy and paste that sucker. For me this took like an hour for my big project to finish.
  • Open this project as a new project (Same Unity Version as VRC)


Importing Pieces

  • Create a new fresh project with the same unity version as before ( currently 2019.4.31f1)
  • Import the CCK https://developers.abinteractive.net/cck/setup/ and the VRC SDK.
  • Import from installers things you think you'll need, like shaders, DPS, dynamic bones.
  • Export an avatar or an entire scene of avatars from your old project:
    • Open up your old project and then in this old project:
    • Drag the entire scene, or the avatar from the scene into your project section.
    • Rightclikc on it in the project and hit "export".
    • Before hitting okay and making the package, note down what it's pulling in; what shaders, what scripts.
    • Export as a unitypackage.
  • Before importing into your new project, ensure you have all the things fully installed from what you noted earlier. An export doesn't pull in dependencies of dependencies so it's likely missing stuff.
  • Import in your exported unitypackage. Drag it into the scene and your stuff is ready.

Conversion

Conversion tools got pretty good.

Main things to do:

  • Convert physbones to Dynamic bones (Or copy from older/remake)
  • Run a conversion script for the AV3 animator controlled components (Gestures, Toggles)
  • Upload

Physbones to Dynamic bones

You have options:

  • Run a converter tool (Varying results, japanese folded 1000 times physbone will convert way worse than simple not godawful ones)
  • Copy dynamic bones from an old project
  • Make new dynamic bones that are similar enough

Converting back from physbones you will lose a few things; like angle limits. However, dynamic bones in CVR supports multithreading and multplayer dynamic bones in the game vanilla so boob touching still on, grabbing not.

  • First install dynamic bones again (1.2). The latest version (1.3) is probably not supported; and it doesn't work with some converters regardless.

Use Converter

The converter I recommend is Dreadrith's, but fluff's might be good too:

After running, check and tweak in playmode. You'll likely need to clean up some wonky colliders and set some radiuses so people can interact with your bones.

More manually

Pumkin's tools (https://github.com/rurre/PumkinsAvatarTools requires the VRC SDK) can help you copy dynamic bones and delete physbones from avatars.

  • Copy dynamic bones from another version of the avatar using component copying or pumkin's tools. Pumkins will also help you clean out physbone stuff.
  • Tweak to fit.

Most of the effort here is just remaking the settings which is a pain.

For Skirts, and other 'clothlikes', forget dynamic bones and use MagicaCloth.

Sidenote about skirts and stuff

CVR supports magia cloth physics: https://assetstore.unity.com/packages/tools/physics/magica-cloth-160144

I gave this a try and it's great.

A video says a thousand words 30 times a second:

Magica Cloth

I'd leave this until you have the rest working.

tl;dr:

Installation

  • Download magica cloth from the unity store in exchange for currency. It's a paid asset so I can't just link it here.
  • Download ABI.MODS folder https://files.catbox.moe/527036.7z - This is a workaround for their modules download being broken as fuck
  • Install, fix broken stuff, put an ABI.MODS folder in your Assets folder. Basically these are modules and without it, it will work in the editor but not in CVR.

CVR's install guide:

Usage

The overall flow is:

  • Create a "MagicaRenderDeformer" on the meshes you want to deform
    • Click Create
  • Create a "Magica Virtual Deformer" as an empty game object on your armature
    • Configure and create a 'virtual mesh' by messing with the reduction settings.
    • Click Create
  • Create a "Magica Mesh Cloth" Object on your armature
    • Start point selection and configure all the bits you do and do not want to move.
    • Tweak the parameters to your liking. There are some presets you can start with.
    • Create Colliders (Sphere, plane and capsule are available). Usually a case of adding them for leg and butt.
    • Add Colliders to the Magia Mesh cloth object
    • Tweak colliders to look nice (Skin-tight and close fits take a lot of tweaking)
  • Upload to CVR

They provide a tutorial for the details:

https://magicasoft.jp/en/magicaclothmeshclothstart-2/

Notes:

  • Red point selection pins the cloth to your model, you'll want everything not move = red, everything move = green. It's pretty easy. If you see LOADS of points, you need to have less polygons on your virtual mesh.
  • If you get a zero vertex error or it doesn't work for some reason, make sure you clicked 'create' on the entire chain of components.

Notes on settings (for a skirt for example): 

>Mass: 15, 1, -0.4
>Drag: 0.01. Controls amount of movement. Lower numbers leads to more movement as far as I can tell.
>World Influence: Hips, Max Speed 3, Movement 0.6, Rotation 0.7. This is basically the opposite of "Inert" from Dynamic Bone. Lowering this will lower how much it moves too.
>Reset after teleport on
>Clamp rotation: 30-50. This is like max angle from PhysBone as far as I can tell.
>Restore distance stiffness: 0.5
>Restore rotation: 0.02-0.005, 0.1
>Collision penetration: Surface, Distance 0.01-0.02, Moving 0.3-1. Making the distance numbers lower seems to make the mesh further away from the collider to prevent clipping more.

VRC to AV3 conversion

The best tool I've used is fluff's:

Converts CGE, is submenu aware, and is pretty painless to use.

  • Install tool
  • run tool on your avatar
  • remove vrc component(s) if not deleted
  • set the viewball and voiceball position (CVR comes with a voice location so sound actually comes from your mouth)
  • You're done

Main differences to VRC: CVR is basically AV 2.0 but with animation controllers part of 3.0. That means toggles, fun effects, gestures, everything. It's unity.

Fluff's Converter captures toggles in submenus. It even captured submenu submenu toggles for me too.

How Fluff's work is it creates a CVR animator and a CVR override in a folder somewhere for you. It then applies the override to the CVR descriptor, and puts the animator controller in the override, and that's the controller that will apply on your avatar in game.

Things added in the Advanced Avatar System will apply to this animator (well it does some funny things on upload to slap it all together behind the scenes) but basically you can change parameters with the AAS.

Notes:

  • The CCK UI is built to enable people to plug in options and then have CVR generate the animator layer for it. What you want is to name the Input the same as the parameter you already made so it doesn't create anything and just uses your existing animator controllers.

More manual guidance will/is available here: Manual_CVR_Conversion (might be wrong)

Gestures

Fluff's converter captures CGE as well!

Hai is working on a version of CGE for CVR but I don't think it's ready yet.

Bugfixing

Ahh my project is such a fucking mess it breaks whenever I try anything and I don't want to keep copying massive backups

I feel you man

    • Delete that one VRC StripPostProcessing script. (see below)
  • Then upload. It kinda worked.

Things probably worth deleting

  • AV3 emulator. No good here. (Assets\Lyuma)
  • Assets/VRCSDK/Dependencies/VRChat/Scripts/ShaderStripping/StripPostProcessing <- This script cursed my project for a while so delete this. (It breaks shader compiling)


Gestures

Note: Fluff's converter should have worked fine.

If not, read https://forums.abinteractive.net/d/656-how-to-add-facial-expressions-hand-gestures-to-your-avatar . If you've ever done 2.0 gestures it's the same - You don't need to fuck around with animator controllers to add gestures, just add face animations to the slots.

From there just hit upload avatar and it should work.

Uploading and Tagging

Tag your shit correctly.

CVR works differently than VRC: They rely on the tagging system to keep content away from minors, and if you mis tag it is treated seriously. The upside is if you DO tag stuff with the right tags, they won't do shit to you if you spoop someone with them, or take your dick out.

Possible problems:

  • No rights to upload content ID. This is the generic failed error messages.
    • Server just down. Try again later.
    • Possible causes: you hit the 10 avatar limit for free users.
  • Gets stuck on "being encrypted": This happens when the avatar isn't written to disk; IE the shader compile failed, or out of disk space, or something. Symptoms include not being able to generate file size estimates and an error in the console saying it couldn't write/find the file.

Worlds

https://forums.abinteractive.net/d/43-the-basics-in-how-to-upload-a-world

And some greentext: 

>make a copy of your vrc project
>remove vrc sdk
>make sure you are on their unity version (currently its the same as vrc)
>restart (just in case)
>import cck: https://developers.abinteractive.net/cck/setup/
>you now have to redo all buttons and teleports etc, so i recommend putting your vrc project on a second monitor as reference
>upload form the menu "Alpha Blend Interactive" you find at the top

You can find everything essential by searching components for "CVR". CVR Interactible is the button for example.
