Skip around this guide based on your needs, although it is suggested to go through this as a set of steps.

Guide to the Guide

This section describes what the step entails, and what to do.

WARNING: There are gotchas in this process
Skipping these tags may result in something going wrong, possibly resulting in the avatar getting deleted or mangled.
NOTE: This guide is long
Common approaches and issues are listed here, most of the guide is how to fix things that go wrong. If sections don't apply to you, skip them!
VERIFY: Do you have a working PC
Small issues during this process get worse over time, these alert you to possible issues early on.
NOTE: The guide is ordered
The guide is structured to be read throughout the importing process, if one step is before another the steps should likely be done in that same order.

Preparing Models

Many file types are supported, with varying supported features.

NOTE: Humanoid Rig Requirements for IK
WARNING: Model Scale
Resonite uses meter scale, many avatars do not. The import process will scale the avatar to average human height with a multiplier.
If that multiplier is >1000 or <0.0001 some creator steps may misbehave.
During the export process from tools like Blender the model can be scaled. If you use the scale applied by Resonite during blender export the avatar will import at 1 scale and not have issues.
This can make it difficult to change avatar meshes later on, if the model scale is inside this range no scaling is required. a CHECK tag in this guide marks when to verify the model scale.

.GLB/.GLTF - Recommended

.FBX - Good

WARNING: Transform Slots
Some FBX files import with additional bones, this can cause many parts of an avatar to break. A CHECK tag in this guide marks when this can be detected.

If the model has these bones, the following features may not work properly:

  • Dynamic bones may appear far more 'wiggly' than normal, and may bend unnaturally.
  • Fingers will crumple at odd angles.
WARNING: Many variants of FBX exist
Two FBX files of the same model may import wildly differently based on FBX versions and slight export option differences, FBX is not suggested for this reason.
NOTE: This format is common
This is the commonly found format in Gumroad and other platforms.

Preparing Textures

NOTE: Animated Textures
A Texture atlas is used for animated textures, see Component:Texture Panner
NOTE: Resolutions
In general 2k is a good size for the body of most textures. It is suggested to export the texture in the destination resolution, instead of resizing inside Resonite.

.WEBP - Recommended

This loads faster and is smaller than PNG, while having the same color support.

NOTE: Asset Conversions
Modifying a texture (such as resizing or stripping the alpha channel) inside of Resonite will re-save the texture as WEBP.

.PNG - Good

Commonly provided with avatars,

Find a World

Importing an avatar is a social event, bring friends, bring popcorn! See how it goes wrong and try out new things, who knew your hands could be scaled to 20x their normal size, and they still worked?! Have a drinking game for every time someone says "oops", have fun with this.

Cultural Considerations

Importing an avatar in a world is like building a Lego set in someone's living room, some people enjoy it and some people would rather you didn't. When in doubt ask if it's OK if you can import an avatar in the world.

NOTE: No does not mean leave
Hosts that ask you not to import an avatar are not asking you to leave (unless they say that as well), being denied can be emotionally a bit confusing but you are more than likely free to stay there. Just not while importing an avatar. If you would still like to import an avatar ask where you can, they may know of other candidate sessions.

Technical Considerations

Importing an avatar can require loading large numbers of possibly large assets directly into the world. Resonite pre-processes cloud saved assets, but it can't do that for imported ones without them being saved.

WARNING: Imported assets are retransmitted by the host
If you import a resource such as a mesh or model, that resource is streamed from your machine to the host, then out to the other users in the session. If the session isn't doing great, or the network of a user in the session is having trouble keeping up, importing assets and creating an avatar may accidently force them from the world.
NOTE: Cloud Assets
Once resources are saved to the Resonite cloud they are downloaded directly from the Cloud, instead of from the host. Assets stored in the cloud are also pre-processed, making them smaller and more quickly loaded (each client independently does this pre-processing for imported assets).
NOTE: Asset Processing
Assets stored in the cloud are also pre-processed, making them smaller and more quickly loaded, but with imported each client independently does this pre-processing.

Permissions

You will require builder permissions to import an avatar, this gives you the ability to modify anything in the world. Users may not be OK with you having that power.

Importing Models

Drag and drop the model from your desktop onto the Resonite window, or import the asset via the File Browser.

A dialog should appear, these options are important:

  1. 3D Model
  2. Regular / Avatar
  3. Auto Humanoid Height (See #Model Scale)
  4. Advanced Settings
    1. Scale - This is not the same as #Model Scale.
    2. Material and Prefer Specular - PBS with Prefer Specular is recommended, but XiexeToon is a close alternative. See #Texturing the Model and PBS_Metallic, PBS_Specular, and XiexeToon
    3. Spawn Material Orbs - This can make #Texturing the Model easier, as an inspector is not required to access the materials. But this is optional.


WARNING: Do not grab the model after it is imported
By default many avatars import in a T or A pose, and the symmetry of the avatar can make #Aligning Hands less error prone.
If grabbed, select Undo in the context menu.
CHECK: Model Scale
Inspect the avatar with a developer tool and look at the scale applied to the root slot. This scale is what is referred to in #Model Scale.

Avatar Creator

WARNING: Ensure you are logged in

A valid account is required to save the avatar to the inventory, and Simple Avatar Protection may soft lock avatars in some cases, see #Protecting an Avatar.

WARNING: You may be blinded when first getting into a newly created avatar.
Geometry over the eyes can cover the viewport, blinding the user in the avatar.
To get out of the avatar equip the previous avatar by clicking it and equipping through the context menu. Switching to desktop mode and using the third person camera is another workaround.
Equipping a new avatar through the inventory will delete the currently equipped avatar, destroying your progress.
See #Near Clip and #Adjusting Proxies to resolve the issue.
If importing with another person, have the blinded user stay in the avatar as the other user follows #Near Clip and #Adjusting Proxies.

An avatar creator is spawned from the home page of the dashboard.

Aligning Head

Place the headset representation over the head of the model and press Align Head Forward, Align Head Up, Align Head Right, Center Head Position, and Try Align Hands in sequence.

Aligning Hands

NOTE: Align the head first
The hands by default use the head as a line of symmetry, aligning the head first makes aligning the second hand unneeded as long as the model is still in a symmetric pose. See #symmetric pose warning.

Adjust one of the hands to align the center and rotation of the hand with the model's hand. If the model is symmetric the other hand will also be aligned, if not uncheck Use Symmetry in the Avatar Creator and place the second hand.

Aligning Tool Anchors

Optionally check Show Tool Anchors in the Avatar Creator to customize the position of the avatar's Tool Anchors, Grab Spheres, and Tool Shelves.

If the tool anchors were adjusted, press Align Tool Anchors in the Avatar Creator before pressing Create

Additional Creator Options

In the Avatar Creator optionally check Setup Volume Meter and Setup Face Tracking (there is no reason not to).

WARNING: Pressing Create When Protect Avatar is checked
If Protect Avatar is checked, whoever clicks Create will have the avatar bound to them with Simple Avatar Protection. This may lock the avatar from being useable by anyone if the user that clicks Create is no registered as Logged In in the current session.
WARNING: Getting into the avatar may blind you
Make sure to have a strategy for getting out of the avatar if you are blinded, see the #blinded warning.

When ready, have the user who is to own the avatar press Create on the Avatar Creator.

Adjusting Proxies

Avatars created with the Avatar Creator have a common hierarchy. The Target slot under each proxy controls where the avatar's body part attempts to be, relative to a provided position input (such as a controller or the headset).

If the avatar head is obscuring part of the viewport: move the Target under Head Proxy backwards. This moves the head back, moving the problem geometry behind the cameras.

WARNING: Adjusting the viewport back can stretch the spine
As the head is balanced farther back, when looking down the spine will stretch up to compensate. This can pull the avatar's feet off the ground when looking down.

Near Clip

Near and far clip can be configured via a Avatar Render Setting being in an avatar when the avatar is equipped.
Add a slot with the Avatar Render Setting to the avatar and set the NearClip to 0.1, from there check if the view is clear, and slowly reduce the value until it just removes the problem geometry.

WARNING: Near clip effects everything
It is suggested to not use near clip whenever possible, as near clip doesn't render anything that distance in front of the camera, including props or some effects.
When possible, it is suggested to move proxies first, and if needed use a very small near clip if still required.
NOTE: Check no clipping happens when moving
Sometimes the avatar can lag slightly behind the player, ensure that when moving the problematic geometry is still not visible.

Texturing the Model

Extract the material orbs from the avatar by inspecting the avatar with a developer tool and look just under the Armature slot of the avatar to find the renderers, those renderers reference materials

NOTE: Extracting materials may not be needed
If material orbs were spawned as part of #spawn material orbs, then the materials for the mesh are already provided.

Import the materials by dragging the textures onto the Resonite window, or import them through the file browser.

Using a material tool edit the material orbs spawned in with the imported avatars, or use the panels spawned in when viewing the materials in the inspector.

Drag and drop the textures into the corresponding slots of the materials.


CHECK: The color of an imported model is often defaulted as gray
When adding the texture, be sure to change the grey color to white to prevent the color looking washed out.
