ImportGuard

Inspect a .unitypackage against your project before importing it, decide what comes in, and import with colliding GUIDs remapped.

The hazard it exists for: a package claiming a GUID that already belongs to a different asset in your project. The paths differ, so Unity's own import dialog looks completely clean while existing references get silently re-pointed.

Usage

Tools > HeavenVR > ImportGuard

Features

• Diffs a .unitypackage against the current project before anything is written
• Flags GUID collisions and remaps them on import instead of overwriting
• Audits scripts inside the package
• Shows what each entry would land on, as a tree
• Drag a .unitypackage straight into the window, or double-click one, or use

Choose Package

• Export a password-protected .unitypackage.enc; opening one prompts for the

password before anything is read. This is a distribution gate, not DRM - the ciphertext and the code that decrypts it both ship in the file, so it only stops "double-click and it just opens," not a determined recipient. Authentication is pluggable (see IUpkgAuthMethod); password is the only method implemented today.
