Frequently Asked Questions

General

Is DV Mod Manager compatible with Unity Mod Manager?

Yes. It reads the same Info.json format and uses the same Mods/ / Mods.inactive/ folder structure. You can use both interchangeably.

Can I use it alongside UMM's built-in manager?

Yes. Both operate on the same folders. DV Mod Manager watches for external changes, so mods moved by other tools are detected automatically.

Does it work on Linux?

Yes. Built with Avalonia UI (cross-platform), published as a self-contained Linux x64 binary.

Does it work with Derail Valley on Proton?

Yes. The manager detects the game via Steam's Linux paths. DVModProfiles also supports Proton/Wine path resolution.

Mod Management

Why does a mod show "No Metadata"?

No Info.json in the mod folder (or it's misspelled). The manager can still activate/deactivate it, but dependency resolution and update checking won't work. See Mod Compatibility.

Does activating a mod change any files?

No. It just moves the folder from Mods.inactive/ to Mods/.

What if I delete a mod folder while the manager is open?

It will be detected and removes it from the list.

Can I install mods while the game is running?

No. All mod operations are locked while Derail Valley is running to prevent file conflicts.

Updates

How does update checking work?

Queries the GitHub Releases API and the Nexus Mods GraphQL API.

Why doesn't my mod show an update? (If you are a developer)

Check that:

• Repository in Info.json points to the right GitHub repo
• Version is a valid version string (e.g. 1.1.0)
• Your release tag parses to a valid version (see Repository & Updates)

Why doesn't my mod show an update? (If you are a normal user)

Contact the mod developer and link him to Repository & Updates

Profiles

JSON vs ZIP export?

• JSON: just the profile metadata (mod IDs, versions, states). Will download mods while importing.
• ZIP: self-contained bundle with all mod files. Larger, but works out of the box. Great for custom mods that aren't public.

See Modpacks.

Does applying a profile delete mods?

No. Mods not in the profile are deactivated (moved to Mods.inactive/), not deleted.

DVModProfiles

Is it required?

No. DV Mod Manager works fully without it. DVModProfiles adds save-game associations, Steam Cloud sync, and per-profile mod settings.

Does it affect multiplayer?

No. Client-side only.

How do I disable Steam Cloud sync?

Open UMM settings in-game (Ctrl+F10 -> Settings), uncheck the sync toggle for DVModProfiles.
