Studio Iyan Texture Vault

Studio Iyan Texture Vault is a Unity Editor-only tool for saving Texture Import Settings to JSON, applying a temporary Standalone BC7 / Max Size 4096 import profile, and restoring the original settings later.

This package is intended for Unity 2022.3 or newer and does not require runtime code.

What It Does

• Scans a selected root GameObject and all child Renderers.
• Finds Texture2D assets used by Material shader texture properties.
• Uses a safe serialized Material fallback for saved texture properties that are not exposed by the current shader.
• Deduplicates textures by asset GUID.
• Saves original TextureImporter and platform settings to JSON.
• Applies a temporary Standalone BC7 / Max Size 4096 profile.
• Restores Texture Import Settings from a saved JSON snapshot.

What It Does Not Do

• This is not a texture upscaler.
• It does not convert source images to true 4K.
• It does not edit, duplicate, move, or destroy source image files.
• It only changes Unity Texture Import Settings, especially platform override settings.

Installation

VCC / VPM

1. Open VCC.
2. Add the VPM listing URL: https://raw.githubusercontent.com/Yunhyuk-Jeong/iyan-vpm/main/vpm.json
3. Add Studio Iyan Texture Vault to your Unity project.

Manual Install

1. Download the release zip from GitHub Releases.
2. Extract the package folder into your Unity project’s Packages folder, or add it through Unity Package Manager from disk.
3. Open the Unity project.

Usage

1. Open Studio Iyan/Tools/Texture Vault.
2. Assign a root GameObject.
3. Click Scan.
4. Click Save Snapshot JSON.
5. Click Apply BC7 / Max Size 4096.
6. Click Restore From Snapshot when you need to restore the original import settings.

Warnings

• BC7 is intended for Standalone/PC use.
• This does not upscale textures.
• Quest/Android should use a separate profile in the future.
• For the MVP, normal maps can still receive the BC7 profile, but the tool logs a warning. A future smart profile can map normal maps to BC5, masks to linear formats, and albedo textures to sRGB BC7.

Release

1. Update package.json version.
2. Update CHANGELOG.md.
3. Commit the changes.
4. Create a tag like v1.0.0.
5. Push the tag.

The release workflow validates that the tag version matches package.json, builds a clean VPM/UPM-compatible zip, generates a SHA256 checksum, and uploads both as GitHub Release assets.
