Avatar in-experience creation

Note

The following guide applies to creators who are familiar with scripting and Roblox Studio and intend to develop experiences that allow user-generated avatar items.

You can publish an experience that allows players to create, customize, and purchase avatar bodies in real time. When purchased, these custom bodies save directly to the player's Roblox inventory, allowing players to equip and wear the custom avatars in other experiences.

Experience owners that implement in-experience avatar creation benefit from Marketplace commissions as both creator of the avatar item and experience owner. If an asset created in-experience is inspected, the item provides a link to the original experience it was created.

You can test in-experience creation in Roblox's Avatar Creator demo.

Note

Avatar assets created in-experience are not listed on the Marketplace, and cannot be resold or traded. At this time, in-experience creation only allows the creation of custom avatar bodies.

How to implement in-experience creation

Use the following instructions and code references to create your first in-experience avatar creation project. The following instructions uses a base body Model that players can modify and customize before publishing.

Before getting started, familiarize yourself with the following:

Import a base body

The base body acts as the initial foundation which users can customize and edit. You can use your own Model, or import a custom asset with the Importer and setup through Avatar Setup.

Base bodies must adhere to Roblox's avatar specifications, and must include components such as the 15 MeshPart instances that make up 6 body parts: head, torso, left arm, left leg, right arm, and right leg, as well as other avatar components.

Note

If you have a single-mesh body, you can try using the Avatar Auto Setup to automatically add all the necessary avatar components.

For references and samples of properly configured avatar bodies, see Avatar references.

Implement editing APIs

To develop a system where users can edit the MeshPart instances on an avatar in your experience for creation, use EditableImage for texture editing, EditableMesh for mesh editing, and WrapDeformer for maintaining skinning and FACS data during mesh edits.

  1. After importing your base body, use the following script to set up your EditableImages, EditableMeshes, and WrapDeformers.

    ```lua
local AssetService = game:GetService("AssetService")

local function setupBodyPart(meshPart, wrapTarget)
    -- Create and attach a WrapDeformer to the MeshPart
    local wrapDeformer = Instance.new("WrapDeformer")
    wrapDeformer.Parent = meshPart

    -- Create an editable mesh for the wrap target's cage mesh
    local cageEditableMesh: EditableMesh =
        AssetService:CreateEditableMeshAsync(Content.fromUri(wrapTarget.CageMeshId), {
            FixedSize = true,
        })

    -- Assign the cage mesh to the WrapDeformer
    wrapDeformer:SetCageMeshContent(Content.fromObject(cageEditableMesh))
end

local function setupRigidMesh(meshPart)
    -- Create an editable mesh from the original MeshPart
    local editableMesh = AssetService:CreateEditableMeshAsync(Content.fromUri(meshPart.MeshId), {
        FixedSize = true,
    })

    -- Generate a new MeshPart from the editable mesh
    local newMeshPart = AssetService:CreateMeshPartAsync(Content.fromObject(editableMesh))

    -- Copy size, position, and texture from the original MeshPart
    newMeshPart.Size = meshPart.Size
    newMeshPart.CFrame = meshPart.CFrame
    newMeshPart.TextureContent = meshPart.TextureContent

    -- Apply the new MeshPart back to the original
    meshPart:ApplyMesh(newMeshPart)
end

local function setupMeshTexture(meshPart, textureIdToEditableImageMap)
    -- If EditableImage already exists for this TextureID, resuse it rather than making a new one
    if textureIdToEditableImageMap[meshPart.TextureID] then
        meshPart.TextureContent =
            Content.fromObject(textureIdToEditableImageMap[meshPart.TextureID])
        return
    end

    -- Create a new EditableImage and apply it as the texture content
    local editableImage = AssetService:CreateEditableImageAsync(Content.fromUri(meshPart.TextureID))
    textureIdToEditableImageMap[meshPart.TextureID] = editableImage
    meshPart.TextureContent = Content.fromObject(editableImage)
end

local function setupModel(model)
    -- Map for reusing EditableImage instances by texture ID
    local textureIdToEditableImageMap = {}
    for _, descendant in model:GetDescendants() do
        if not descendant:IsA("MeshPart") then
            continue
        end

        -- Configure MeshPart based on WrapTarget presence
        -- If WrapTarget is present, add a WrapDeformer child with an EditableMesh
        -- Otherwise, apply EditableMesh to the MeshPart directly
        local wrapTarget = descendant:FindFirstChildOfClass("WrapTarget")
        if wrapTarget then
            setupBodyPart(descendant, wrapTarget)
        else
            setupRigidMesh(descendant)
        end

        -- Configure the EditableImage for the MeshPart
        setupMeshTexture(descendant, textureIdToEditableImageMap)
    end
end
```

  2. Create EditableImage tools that allow players to recolor, draw, or add stickers to your base body. You can leverage APIs in like DrawImage(), DrawRectangle(), WritePixelsBuffer().

    • For advanced transformations, DrawImageTransformed() allows you to specify position, rotation, and scale when drawing one EditableImage onto another. Similarly, DrawImageProjected() works much like DrawImage() but projects the drawn image properly if the EditableImage instance is used with a MeshPart.

        ```lua
  local function recolorTexture(
      meshPart: MeshPart,
      color: Color3
  )
      local bodyPartTexture = AssetService:CreateEditableImageAsync(meshPart.TextureID)
      meshPart.TextureContent = Content.fromObject(bodyPartTexture)

      bodyPartTexture:DrawRectangle(
          Vector2.new(0, 0),
          bodyPartTexture.Size,
          color,
          0,
          Enum.ImageCombineType.Overwrite
      )
  end

  local function applySticker(
      meshPart: MeshPart,
      textureCoordinate: Vector2,
      stickerId: TextureId
  )
      local bodyPartTexture = AssetService:CreateEditableImageAsync(meshPart.TextureID)
      meshPart.TextureContent = Content.fromObject(bodyPartTexture)

      local stickerTexture = AssetService:CreateEditableImageAsync(stickerId)
      bodyPartTexture:DrawImage(textureCoordinate, stickerTexture, Enum.ImageCombineType.BlendSourceOver)
  end

  local function applyStickerProjected(
    meshPart: MeshPart,
    targetMesh: EditableMesh,
    stickerId: TextureId,
    raycastHitPos: Vector3
  )
    local bodyPartTexture = AssetService:CreateEditableImageAsync(meshPart.TextureID)

    local relativePos = meshPart.CFrame:PointToWorldSpace(raycastHitPos)
    local direction = (workspace.CurrentCamera.CFrame.Position - relativePos).Unit

    local projectionParams: ProjectionParams = {
        Direction = meshPart.CFrame:VectorToObjectSpace(direction),
        Position = meshPart.CFrame:PointToObjectSpace(relativePos),
        Size = Vector3.new(1, 1, 1),
        Up = meshPart.CFrame:VectorToObjectSpace(Vector3.new(0, 1, 0)),
    }

    local stickerTexture = AssetService:CreateEditableImageAsync(stickerId)
    local localBrushConfig: BrushConfig = {
        Decal = stickerTexture,
        ColorBlendType = Enum.ImageCombineType.BlendSourceOver,
        AlphaBlendType = Enum.ImageAlphaType.Default,
        BlendIntensity = 1,
        FadeAngle = 90.0
    }

    bodyPartTexture:DrawImageProjected(targetMesh, projectionParams, localBrushConfig)
  end
  ```

  3. Using WrapDeformer and EditableMesh, create tools for editing mesh deformations on your body.

    1. WrapDeformer handles the live deformations of the rendered MeshPart geometry while maintaining the underlying skinning and FACS data.

    2. EditableMesh allows you to modify the cage mesh that the WrapDeformer responds to.

      1. Use WrapDeformer:SetCageMeshContent() to apply the EditableMesh instance that represents the relevant cage mesh to the WrapDeformer.
      2. Use EditableMesh, such as SetPosition(), to deform vertices and edit the shape of the MeshPart.
      local function deformBodyPart(
    meshPart: MeshPart,
    controlPointCenter: Vector3,
    controlPointRadius: number,
    controlPointDeformation: Vector3
)
    local wrapTarget = meshPart:FindFirstChildWhichIsA("WrapTarget")
    local cageMeshId = wrapTarget.CageMeshId
    local wrapDeformer = Instance.new("WrapDeformer")
    wrapDeformer.Parent = meshPart

    local cageEditableMesh = AssetService:CreateEditableMeshAsync(cageMeshId)
    local verticesWithinSphere =
        cageEditableMesh:FindVerticesWithinSphere(controlPointCenter, controlPointRadius)
    for _, vertexId in verticesWithinSphere do
        local vertexPosition = cageEditableMesh:GetPosition(vertexId)
        cageEditableMesh:SetPosition(vertexId, vertexPosition + controlPointDeformation)
    end

    wrapDeformer:SetCageMeshContent(Content.fromObject(cageEditableMesh))
end

Create creation prompt

After setting up your base body and editing APIs, create a prompt for users to create and purchase from the experience using AvatarCreationService:PromptCreateAvatarAsync().

export type BodyPartInfo = {
	bodyPart: Enum.BodyPart,
	instance: Instance --Folder with Created MeshParts
}
export type BodyPartList = {BodyPartInfo}

local function publishAvatar(bodyPartInstances: BodyPartList, player: Player, tokenId: string)
	local humanoidDescription = Instance.new("HumanoidDescription")
	for _, bodyPartInfo in bodyPartInstances do
		local bodyPartDescription = Instance.new("BodyPartDescription")
		bodyPartDescription.Instance = bodyPartInfo.instance
		bodyPartDescription.BodyPart = bodyPartInfo.bodyPart
		bodyPartDescription.Parent = humanoidDescription
	end

	local success, result, bundleIdOrErrorMessage, outfitId = pcall(function()
		return AvatarCreationService:PromptCreateAvatarAsync(tokenId, player, humanoidDescription)
	end)
	if success then
		if result == Enum.PromptCreateAvatarResult.Success then
			print("Successfully uploaded with BundleId: ", bundleIdOrErrorMessage)
      print("Successfully uploaded with OutfitId: ", outfitId)
		else
			print("Unsuccessfully uploaded with error message:", bundleIdOrErrorMessage)
		end
	else
		print("Avatar creation unsuccessful")
	end
end

AvatarCreationService:PromptCreateAvatarAsync() takes a HumanoidDescription parameter to represent the avatar intended for purchase or creation. For avatar creation, the character's HumanoidDescription must include new assets to be created for each of the 6 body parts (Head, Torso, RightLeg, LeftLeg, RightArm, LeftArm). Optionally, it can also include a new Hair accessory.

To support this, the HumanoidDescription should include 6 BodyPartDescription children. Each BodyPartDescription.Instance property references a Folder which includes all of the MeshPart instances that make up the body part. For example, the LeftArm folder contains LeftHand, LeftUpperArm, and LeftLowerArm MeshParts. The BodyPartDescription.BodyPart property should also be set to the relevant BodyPart.

Each of the 15 MeshPart body parts must include:

The provided HumanoidDescription should not include any pre-existing asset IDs to represent body parts or accessories on the intended creation. On the other hand, the HumanoidDescription may include the humanoid scales of BodyTypeScale, HeadScale, HeightScale, WidthScale, and ProportionScale. Be mindful of the scales that a base body is imported with so that they match the scales provided to the HumanoidDescription.

Include accessories

If including an accessory, such as hair, the HumanoidDescription should include a child AccessoryDescription where:

Generate an avatar creation token

AvatarCreationService:PromptCreateAvatarAsync() takes an Avatar Creation Token ID parameter. This token is the key for creations from your universe, and it is what you can use to set the price of avatar creation from your experience. For instructions and additional details on generating tokens, see Avatar Creation Tokens.

After purchasing and generating your token, you can inspect the token in the Creator Hub to find the ID which you can then use for the AvatarCreationService:PromptCreateAvatarAsync() API.

Respond to players joining by attribution

Avatar bundles created in-experience include an attribution link to the original experience the avatar was created. If the avatar is inspected by another player, a prompt displays providing an option to visit the experience where the avatar was created.

To handle players joining your experience using this attribution link, use Player:GetJoinData() and parse the returned table for GameJoinContext.

GameJoinContext includes the following table values:
