Vrchat Avatar Comes Out Pink After Upload

This folio is under construction.

Welcome! So you want to create a VRChat avatar. Trouble is, this is all new to you and you have no thought where to begin. The documentation is confusing and incomplete, all the guides on youtube are diverse levels of outdated, and everyone assumes y'all know certain things or glosses over certain steps.

This article volition guide y'all through the whole process of taking a uncomplicated, extant humanoid model and publishing it equally a basic avatar on VRChat, while explaining common tools and core concepts. By basic, we mean an avatar with absolutely no actress features--just the defaults. In one case you lot successfully master this process, yous tin build on it to larn how to do more complicated things!

If yous need assist while following this guide please ship a message explaining your issue in detail (no need to ask for permission first) in the #avatars-3-help channel of the official VRChat discord and await patiently for a reply.

Installing Blender

Avatars are prepare and published using Unity. If your avatar comes from a packet that was already prepared for VRChat by someone else, you can skip ahead to the Unity section.

Withal, in many cases, yous are going to want to modify or meliorate the 3D model or models that will be in your avatar—for example, if you want to optimize performance, create facial expressions, adjust clothes, etc. These changes have to be done using 3D modelling software. At that place are several possible choices, merely Blender is a complimentary and open source, and very powerful, and then is the typical choice in the VRChat community.

Every bit such, let's begin by installing Blender 2.83 or 2.93. While 2.83 is used in this guide, 2.93 is very similar. Use one of the links beneath and follow the instructions.

• Download Blender 2.83
• Download Blender 2.93

Blender and the Cats plugin.

Done? Y'all should now have a new, open Blender project window in front end of you (if not, just run Blender). Just before we go on, nosotros're also going to install the Cats plugin. This addition for Blender, created past some VRChat community members, simplifies some of the more complex common avatar-making tasks and will help you brand fewer mistakes.

• Download and instructions for the Cats Plugin

Once you tin run into Cats panel, as shown on the picture, you're ready to proceed.

Blender has a lot of interface elements and may seem daunting at starting time, just you will rapidly get used to it. For at present, all you demand to know is that yous can:

• Zoom in and out using the mouse wheel.
• Rotate around the scene by pressing the center mouse button (usually likewise the mouse wheel).
• Motility laterally through the scene by property downwards shift + middle mouse button and dragging the scene.
• Employ the Undo options in the Edit menu if you make a mistake.

Preparing a 3D model

Practica Spica past くまきち商店ワークス

The next thing we need is a 3D model. Y'all can create your own from scratch, just you could as well use a gratis model available on the cyberspace, buy ane, or committee one according to your specifications. For this guide, we'll be using Practica Spica, a gratuitous, very simple model.

• Download the Practica Spica model and texture

Unpack the zip somewhere in your computer. It contains a 3D model in .fbx format and textures in .png format . Other avatars might come in different formats, but with the right plugins Blender should exist able to import and convert most of them.

Import and ready the model

Click the Import Model push in the Cats plugin panel, find and double click the fbx model. The Cats plugin will delete the default objects from your scene (you don't need them) and you'll see something similar to this image. Don't be alarmed! Everything is under control.

Look at the tree in the top correct corner—that's the Outliner. It displays the elements in your scene and the relationship between them. You'll come across everything is under a root orange node chosen Armature, because your avatar can be posed or animated using a skeleton. Nether information technology yous'll meet a Pose, Armature and 5 orange objects.

The Cats plugin only supports avatars with an Armature.

Make sure the orange Armature root is notwithstanding selected and click the Set Model button. The Cats plugin will take a few seconds to run a batch of automated operations on your avatar, and when it'south washed information technology should look like this moving-picture show. Almost ready to use!

If y'all click the wrench abreast Fix Model, you'll run into the list of operations Gear up Model runs. You can disable 1 or more of them if you don't want them. For example, the "Join Meshes" performance merged the avatar's five objects into a single one. Normally y'all want this, because information technology makes the avatar more efficient and amend ranked, but if for some reason you lot want to go on them separated y'all could plough that off.

Optimization

At this point yous might normally want to make your model more than efficient and lightweight. This has two chief benefits:

1. Information technology prevents the Performance Ranking System (PRS) from tagging your avatar every bit poorly optimized, which might result in some users non seeing it by default.
2. Information technology improves the feel of VRChat users in the same world equally you lot with lower end hardware, significant they're less probable to manually block your avatar (and it'south just proficient manners!)

Open the Documentation on the Performance Ranking Organization. We're going to compare our model with the values on the tables.

Not everything in the PRS has to be dealt with while creating your 3D model; well-nigh of them are for later. The main categories you want to go on an eye on for at present are:

Polygons

Select the root orangish node in the outliner, making sure you are in Object Mode (the default). You tin can use the dropdown in the summit left corner of the 3D view to change back if y'all aren't. So wait at the value for Tris (triangles) on the condition bar; that's the base of operations amount of polygons. Later, if you lot add together props to your avatar they will besides count towards the full.

Right at present, as yous tin can run into, this avatar has a very low corporeality of polygons; even on the Quest information technology ranks as "Good".

In Blender two.9x, you may have to enable statistics in the condition bar context menu.

Bones

Select the greenish (non orangish!) Armature node in the Outliner to get into Armature Edit Style. The status bar will display the amount of bones. This avatar has a minimal skeleton, and so the amount of bones volition rank "Splendid".

Skinned Meshes

A skinned mesh is a collection of triangles affected past the armature. They're represented by the dark-green triangle icons in the Outliner. Our model (later beingness stock-still by the Cats plugin) only has one. "Splendid!"

Material Slots

Each material in each mesh counts as 1 cloth slot. Materials are represented by a ruby sphere; our model only has one, because it already comes pre-atlased and only has one skinned mesh. "Excellent" as well.

In conclusion, optimization is not required for this avatar, but if you desire to learn more about optimization, read on most:

• Decimation
• Armature optimization
• Texture atlasing

Shape keys

Shape keys—also known (in Unity) every bit Blendshapes—contain transforms that reconfigure the geometry of a mesh when they are applied. For example, you can transform a neutral mouth into a smiling oral cavity.

List of shape keys, with left glimmer selected in mesh edit mode.

Since they are an attribute of the mesh, click go into Mesh Edit Mode by clicking the greenish triangle node in the Outliner, then click the same icon down below to open up the Object Information Properties and finally locate the Shape Keys section. Our avatar already comes with many Shape Keys.

You can utilise Blendshapes on whatsoever part of your model, but most VRChat avatar makers are interested in three specific features:

Visemes

The visual positions of the avatar's mouth (or equivalent) that stand for sure sounds. VRChat detects (when the user talks) and supports 15 visemes, merely it's up to you lot to create them in your model.

The Cats plugin simplifies this process by mixing only 3 visemes in club to create the remaining ones, equally you can see in the Visemes section of the Cats plugin interface. Even so, browsing through the list of Shape Keys, yous'll find this avatar already has every viseme. No need to do anything!

If y'all need to create your ain visemes, read more than on How to create Visemes.

Facial expressions

Most users want their avatar to take facial expressions that they can trigger manually. If you lot browse through the list of Shape Keys you'll see this avatar already comes with several, although calculation them will be beyond the telescopic of this guide.

You can read more than on How to add Facial Expressions.

Imitation blinking

VRChat supports simulated middle movements, including blinking. Proficient quality blinking is unremarkably accomplished with Blendshapes. You tin can meet in the Eye Tracking department of the Cats plugin interface that it expects y'all to create iv: Blink left, Blink right, Lowerlid left and Lowerlid right. All of these are already included with this avatar.

Unfortunately this setup was made for an older version of the SDK. VRChat now expects a blendshape that blinks both eyelids at the aforementioned time. Let's make one by taking vrc.blink_left and vrc.blink_right and combining them together!

Leave Mesh Edit Mode and go back to Object Style by unselecting the Trunk mesh node in the Outliner (light-green triangle) or using the dropdown in the top left corner. Then select vrc.blink_left and vrc.blink_right in plow and drag the Value slider on each all the manner to 1.0. Practica should now accept both of her eyelids downward.

Click the push with the small-scale downward arrow to the correct of the list and select New Shape Key from Mix. Rename the new key to Glimmer. You can exam the new cardinal past setting the value of vrc.blink_left and vrc.blink_right to 0.0 and temporarily setting the value of Blink to 1.0 (leave everything at 0 when you lot're washed!)

You should practise the aforementioned thing with vrc.lowerlid_left and vrc.lowerlid_right, combining them into a single central which nosotros'll call Lowerlid.

Shape keys should almost always be created last; many mesh-editing features will break shape keys or be prevented by their existence.

Export the model

Now that you've prepared your model it's time to export it. Yous should exercise this using the Consign Model button in the Cats plugin console. No thing what the original format of your model was, we want to consign it as a .fbx, which is a format Unity supports. The Cats plugin will set all the options in the Consign dialog correctly for VRChat, so you only accept to enter a filename.

Don't forget to save your Blender project as well, which creates a .blend file. In the time to come you'll be able to return to it if you ever want to make changes to your model, such every bit calculation more bones, splitting meshes, creating new blendshapes, etc.

Installing Unity with the SDK3 - Avatars

The VRChat documentation contains instructions on how to set the SDK spread throughout a handful of unlike manufactures. The procedure can exist summarized as:

1. Install Unity Hub.
2. Add together the currently supported version of Unity to Unity Hub.
3. Create a new 3D Project in Unity Hub using the correct version of Unity, or add an existing projection to it.
4. Download the VRChat SDK3 - Avatars and import it into your projection.

Installing Unity Hub and Unity

Install Unity Hub and Unity as explained in this article, and then come back here.

While installing Unity, make sure you lot tick Android Build Support. You'll need this if you ever desire to build for the Oculus Quest. If you missed it, don't worry! Yous tin can add together it later past clicking the three vertical dots in the top right corner of the rectangle shown in the Installs tab and then using Add Modules.

When you lot're done, the Installs tab should look like the one in the flick.

Creating a Projection with the VRChat SDK

Before creating your project decide whether you lot want to build for the PC or for the Quest. You lot can go along multiple avatars in the same project; however, the project can but target one platform. It'south possible to convert an existing project from i platform to the other, but information technology'south a slow, issue-prone procedure.

PC target (StandaloneWindows64)

Your project will build avatars that VRChat will show to users in Desktop mode, in a SteamVR headset (HTC, Valve, Pimax, etc.), or in an Oculus Quest/ii headset that is being supported by PC hardware through Oculus Link or some other such method. Performance limits are much more relaxed and all features are supported.

Quest target (Android)

Your project volition build avatars that VRChat will show but to users using a stand-alone Oculus Quest/2 headset, not supported by PC hardware. Performance limits are much tighter and many features aren't supported, including custom shaders, transparent particles, dynamic basic, constraints, etc.

Head on over to the Projects tab in Unity Hub and click the New button. Ready the template to 3D, give your project binder a descriptive proper name and make sure you identify it in a fast medium (SSD highly recommended) with plenty of complimentary space.

Shortly afterward you click Create, Unity Hub will minimize and your new project will open.

Change the build target to Android

Quest but! Skip this step if y'all're creating a PC project. Otherwise, go to:

File > Build settings...

Click Android followed by Switch platform, then close the Build settings dialog.

This guide volition use a projection in PC build mode, but the remaining instructions should be the same for Quest mode.

Import the SDK

Download the SDK3 - Avatars from the VRChat website to your hard bulldoze.

To import it to your project, in Unity, use:

Avails > Import parcel > Custom package...

Unity will display a list of everything in the bundle. Confirm by clicking Import without unticking anything. After a infinitesimal, a VRCSDK folder will appear in your Assets, in the Projection panel.

Importing packages and running scripts volition often result in files and folders beingness created in the root of your Assets folder. To go on things organized, we recommend always placing your avatar avails in their own folders.

A new menu, VRChat SDK, should now be available. Use information technology to open the VRChat SDK panel:

VRChat SDK > Testify Control Panel

Log in with your VRChat username and password, and dock it somewhere that makes sense to you (I like to put it on the left mitt sidebar.)

At the meridian of the Scene console, locate the light seedling icon (third from the left) and untoggle it in order to disable scene lighting. Nosotros don't care about scene lighting, because while you're going to use a scene for setting up your avatar, the scene itself will not be office of the avatar. In VRChat, the lighting is decided by the earth you lot're in.

Congratulations—you're at present ready to publish avatars!

Simply native VRChat accounts with a trust rank of New User or college can publish content. If your VRChat account is tied to another platform, you must convert information technology.
