EAUploader.Editor.Prefab.API

Public API related to operating on prefabs and getting their information. Defined in EAUploader.Editor.Prefab.API.cs, EAUploader.Editor.PrefabPreview.API.cs, EAUploader.Editor.Shader.API.cs, EAUploader.Editor.PrefabUtility.API.cs, and EAUploader.Editor.VRM.API.cs in Editor/Public EAUploader API/ (one class per file).

using EAUploader.Editor.Prefab.API;

Class	Description
PrefabAPI	Provides prefab operations and information
PrefabPreviewAPI	Provides prefab preview images
ShaderAPI	Provides shader checks
PrefabUtilityAPI	Provides avatar information
VRMAPI	Provides VRM import (only when VRM Converter for VRChat is installed)

Note

When using methods that return VRCAvatarDescriptor or PipelineManager, add references to the VRChat SDK assemblies to your extension’s assembly.

PrefabAPI

---

Method	Type	Description
UpdatePrefabInfo	Void	Re-initializes the managed prefabs (managed folder, migration, missing preview images)
ImportPrefab	Void	Brings the prefab at the specified path into EAUploader (creates or updates a managed Prefab Variant)
GetPrefab	GameObject	Gets the prefab at the specified path
ShowDeletePrefabDialog	Bool	Shows the prefab deletion confirmation
DeletePrefabPreview	Void	Deletes the preview image of the prefab at the specified path
PinPrefab	Void	Toggles pinning of the prefab at the specified path
GetAvatarDescriptor	VRCAvatarDescriptor	Gets the VRCAvatarDescriptor of the prefab at the specified path
IsPinned	Bool	Checks whether the prefab at the specified path is pinned
SavePrefab	Void	Saves a prefab

public static void UpdatePrefabInfo();
public static void ImportPrefab(string prefabPath);
public static GameObject GetPrefab(string prefabPath);
public static bool ShowDeletePrefabDialog(string prefabPath, Action<bool> completed);
[Obsolete] public static bool ShowDeletePrefabDialog(string prefabPath);
public static void DeletePrefabPreview(string prefabPath);
public static void PinPrefab(string prefabPath);
public static VRCAvatarDescriptor GetAvatarDescriptor(string prefabPath);
public static bool IsPinned(string prefabPath);
public static void SavePrefab(GameObject prefab, string path);

• GetPrefab and GetAvatarDescriptor return null if the prefab is not found.
• ImportPrefab creates a managed Prefab Variant (Assets/EAUploader/Prefabs/<item name>/) for an unmanaged prefab, and updates the information for a managed one. The source prefab is not changed. No Variant is created for prefabs outside Assets/, inside Assets/EAUploader/, or that already have a Variant.
• ShowDeletePrefabDialog(path, completed) opens the deletion confirmation modal inside the EAUploader window and returns true if the modal opened. completed(true) is called when deletion completes, and completed(false) when cancelled. Together with the prefab, the source prefab and materials and textures used only by that item are also deleted.
• The one-argument ShowDeletePrefabDialog(path) is [Obsolete]. For compatibility, it shows Unity’s standard confirmation dialog and returns true when deletion completes.
• PinPrefab pins the prefab if it is not pinned, and unpins it if it is.
• SavePrefab saves the GameObject as a prefab at the specified path and runs ImportPrefab.

PrefabPreviewAPI

---

Method	Type	Description
GeneratePreview	Texture2D	Generates a preview image of a prefab
GenerateAndSaveAllPrefabPreviews	Void	Generates and saves preview images for all prefabs that do not have one
SavePrefabPreview	Void	Saves a prefab’s preview image
LoadTextureFromFile	Texture2D	Loads a texture from a file
SaveTextureToFile	Void	Saves a texture to a PNG file
GetPreviewImagePath	String	Gets the path of a prefab’s preview image
GetPrefabPreview	Texture2D	Gets a prefab’s preview image

public static Texture2D GeneratePreview(GameObject prefab);
public static void GenerateAndSaveAllPrefabPreviews();
public static void SavePrefabPreview(string prefabPath, Texture2D preview);
public static Texture2D LoadTextureFromFile(string filePath);
public static void SaveTextureToFile(Texture2D texture, string filePath);
public static string GetPreviewImagePath(string prefabPath);
public static Texture2D GetPrefabPreview(string prefabPath);

• Preview images are saved to Assets/EAUploader/PrefabPreviews/{Prefab GUID}.png. Preview images are kept when renaming.
• GeneratePreview generates a 1200×900 image.
• GetPrefabPreview returns null if no preview image exists.

ShaderAPI

---

Method	Type	Description
CheckShaders	Void	Checks the shaders of all prefabs in Assets
GetExistingShaders	List	Gets a list of the group names of shaders installed in the project
CheckShadersInPrefabs	Void	Checks the shaders of the specified prefab
CheckAvatarHasShader	Bool	Checks whether all shaders required by an avatar exist

public static void CheckShaders();
public static List<string> GetExistingShaders();
public static void CheckShadersInPrefabs(string prefabPath);
public static bool CheckAvatarHasShader(GameObject avatar);

• CheckShaders and CheckShadersInPrefabs show a dialog if there are prefabs with missing shaders.
• CheckAvatarHasShader returns true if no shaders are missing. It does not show a dialog.

PrefabUtilityAPI

---

Method	Type	Description
GetAvatarHeight	Float	Gets the avatar’s height (viewpoint height)
CheckAvatarHasVRCAvatarDescriptor	Bool	Checks whether the avatar has a VRCAvatarDescriptor
CheckAvatarIsVRM	Bool	Checks whether the avatar is VRM
CheckAvatarHasTandO	Bool	Checks whether the avatar has AvatarOptimizer’s TraceAndOptimize
GetAvatarDescriptor	VRCAvatarDescriptor	Gets the avatar’s VRCAvatarDescriptor
GetPipelineManager	PipelineManager	Gets the avatar’s PipelineManager

public static float GetAvatarHeight(GameObject avatar);
public static bool CheckAvatarHasVRCAvatarDescriptor(GameObject avatar);
public static bool CheckAvatarIsVRM(GameObject avatar);
public static bool CheckAvatarHasTandO(GameObject avatar);
public static VRCAvatarDescriptor GetAvatarDescriptor(GameObject avatar);
public static VRC.Core.PipelineManager GetPipelineManager(GameObject avatar);

• GetAvatarHeight returns the Y coordinate of the VRCAvatarDescriptor’s ViewPosition. Returns 0 if there is no VRCAvatarDescriptor.
• CheckAvatarHasVRCAvatarDescriptor returns false if avatar is null.
• CheckAvatarIsVRM always returns false if VRM Converter for VRChat is not installed.
• CheckAvatarHasTandO always returns false if AvatarOptimizer is not installed.

VRMAPI

---

Available only when VRM Converter for VRChat is installed (when HAS_VRM is defined).

Method	Type	Description
ImportVRM	Void	Imports a VRM file and shows the conversion window

public static void ImportVRM(string path = null);

• If path is omitted, a file selection dialog is shown.
• Files inside the project’s Assets cannot be specified.
• The imported VRM is saved to Assets/VRM/{file name}.prefab.
