So I downloaded the backroom map by lethamyr's site and I extracted it. When I want to open it on Custom map loader app, I always get this message even if the folder is: program files>Epic Games>Rocketleague>MapFiles

Help me pls I'm sure it's one of my little mistake

Hey everyone,

Ever since Epic rolled out Easy Anti-Cheat (EAC), using memory-based tools for online cosmetics has become much more limited. If you still want custom setups without injecting into Rocket League, I built a tool that can help.

I'm releasing Alphy v2.0.0, a completely free Rocket League cosmetic mod manager. I got tired of manually swapping .upk files, tracking vanilla backups, and managing custom decals, bodies, goal explosions, balls, and boost meters, so I automated the process.

(Alphy is a mod manager only. It does not come with pre-installed mods or paid items. You import your own mods, manage your own presets, and use the integrated plugins if you want to create swaps.)

🛡️ A NOTE ON SECURITY / FALSE POSITIVES

Some antivirus tools or VirusTotal engines may flag modding utilities because they edit game files, launch helper scripts, or perform automated file operations.

Alphy does not inject into Rocket League, does not hook game memory, and does not need to run inside the game process.

Alphy works by editing local asset files, creating backups, and restoring files when needed.

Starting with v2.0.0, Alphy is transitioning to a closed-source official build for security reasons because the app now connects to cloud authorization services. The public repositories remain available for downloads, documentation, and legacy source history.

Official builds are not obfuscated.

✨ WHY USE ALPHY?

• Visual UI: Browse mods with icons, categories, search, active counts, and a cleaner modern interface.
• No Injection: Alphy operates outside of game memory and only handles local file operations.
• Smart Backups: Before changing Rocket League files, Alphy creates backups and can restore files when needed.
• File Mismatch Detection: If you verify game files or Rocket League updates, Alphy can detect mismatches and reset mod states properly.
• Built-in Mod Importer: Import supported .upk, .bnk, and compatible custom texture mods directly through the app.
• Custom Texture Support: Supports compatible custom decals, custom balls, and custom boost meters.
• Plugin System: Extra tools can be installed through the built-in plugin manager.

👤 DISCORD ACCESS IN ALPHY v2.0.0

Starting with Alphy v2.0.0, users must authorize with Discord to use the official build.

This is done through Discord OAuth. Alphy does not get your Discord password.

To use Alphy:

1. Join the official Alphy Discord server:
   https://discord.gg/A2mrCVdpPw

2. Make sure you have the Member role.

3. Open Alphy and click Authorize with Discord.

4. Approve the Discord authorization page.

5. Paste the authorization code back into Alphy.

Once authorized, Alphy verifies your Discord server roles and unlocks the correct access for your account.

For now, the Member role is required to use the app. In the future, different roles may unlock different permissions such as beta features, plugins, or custom tools.

Sessions currently last up to 30 days, so you do not need to authorize every time you open the app.

🔒 PRIVACY & NETWORK SECURITY

Alphy uses a stateless Cloudflare Workers backend for Discord role verification.

During authorization, Alphy sends the temporary Discord authorization code to the Worker. The Worker then asks Discord whether your account belongs to the official Alphy server and which roles you have.

Alphy does not receive your Discord password, email, private messages, friends list, or Rocket League account information.

Alphy does not use a user database and does not permanently store your IP address, Discord profile, roles, or personal information after the role check.

Because the authorization service is hosted on Cloudflare, Cloudflare may process normal network-level request information such as IP address, approximate region, timestamps, user agent, request path, and security/routing data. This is standard for websites and cloud services and is used for routing, uptime, abuse prevention, and DDoS protection.

🧩 PLUGIN SYSTEM & ALPHY SWAPPER

The Plugin Manager

To access the Plugin Manager, click the Plugins button in Alphy. This menu lets you browse, download, install, and update official plugins directly from the cloud.

Official Plugin: Alphy Swapper

Alphy Swapper is an advanced asset swapper that lets you generate your own custom mods by swapping internal Rocket League .upk files.

Because it is integrated with Alphy, it is fully automated:

• Zero Configuration: It automatically detects your Rocket League directory from Alphy.
• Smart Exporting: Generated swaps are routed directly into your Alphy mods/ folder.
• Instant Refresh: Once a swap is generated, Alphy refreshes and shows it immediately.
• Multiple Engines: Choose between different swapping engines if one swap does not work correctly.

Current engines include:

• RLUPKTools: Default and recommended engine.
• Alphy Engine: Fallback engine for swaps that do not work with the default engine.
• Alphy Pro [BETA]: Beta-only engine available to selected testers.

Switching engines can cause instability, so RLUPKTools is recommended unless a specific swap requires another engine.

⚠️ PREREQUISITES

Alphy Swapper uses Python for some backend asset operations.

The plugin should automatically prepare what it needs, including required Python modules such as cryptography.

If you still get a cryptography error, install Python 64-bit and run this in CMD:

1. python -m pip install --upgrade pip
2. python -m pip install cryptography

🛠️ TECHNICAL DETAILS

• Supports RLUPKTools-based mods
• Supports imported custom texture packs when compatible
• Uses Discord OAuth for role verification
• Uses Cloudflare Workers for stateless authorization checks
• Client-side cosmetic changes only

(Note: Alphy is client-side only. Since it swaps local assets on your computer, other players will only see your normal vanilla items.)

📦 REPOSITORY STATUS

Starting with Alphy v2.0.0, Alphy is now closed-source for security reasons.

The public repositories remain online for downloads, documentation, and legacy source history.

So I just stumbled across this video: https://www.youtube.com/watch?v=6LiYC4dZhqU

In this video the creator showed how to get alpha boost in the game by adding a upk file and that changes the bubble boost to alpha boost. But I'm not sure how this works so I'm wondering if this is safe and allowed by the easy anti cheat cuz I'm not trying to get banned.

Thanks guys.

Hey, been working on this for a while. It's a Node.js CLI tool called RLItemMod that lets you swap the visual effects of items you own with other items in the game (e.g. making your boost look like Alpha Reward, or your explosion look like Hades Bomb).

what makes this different from RLDetect's item mod is that it patches the .upk locally and never downloads or makes any sort of request outside of your PC!

It works by calling into a Python engine that handles the full UPK binary format -AES decryption, LZO decompression, name table offset shifting - so it doesn't corrupt the game files like naive hex editors do.

Source code: https://github.com/bitsfdb/RLItemMod

i am aware of RLDetect but they download the files directly from their servers (which is really inconvenient and raises some concerns)

HELP.

So I've installed the workshop maps plugin for rocket league from the game not the site of bakkesmod bc when I tried to download it I can't.

So here I am, for example , I want to download the first map "orbital rings" this message pops up saying:" Access denied".

I put the application of bakkesmod as administrator and put it on the "documents" folder but still same issues.

help please

Can someone mod in a USPS LLV (mail delivery vehicle)??? I'm a USPS mailman and part-time RL player, would be hilarious to hit some flip resets in this thing xDDD

Bitte bring diesen gottverdammten Knock-out Modus wieder rein das war der beste Modus, den ich je gespielt hab in ganzen Leben❤️🫶🏻🫶🏻🫶🏻🫶🏻

Hey everyone,
I’m trying to play Hornet’s Nest by DMC on Epic Games Rocket League, but every Steam Workshop downloader is either blocked, 404’ing, or redirecting to the SteamCMD tutorial. RocketLeagueMaps only has the video, and none of the usual sites can fetch the .udk anymore.

If anyone with Steam Rocket League still has the map downloaded, could you send me the Hornets_Nest.udk file?
I just need the file so I can load it through Workshop Loader.

Thanks a ton to anyone who can help.

Does anyone know where i can find an existing Underpass .udk map file (old Workshop) for a rings map?

Who never dream to finally have a Hatsune Miku decals for the Fennec ???
Who never dream to finally see Kasane Teto on Rocket League, dream's come true.
Saddly idk how to get a custom player anthem to complete the set :(
(.wem file didn't work since a while for RL)

Since Rocket League files are now using the .ewem format, is there any other way to get custom player anthems?

I’m wondering if there’s still a way to do it, either through plugins, like before by modifying some files, or even by trying to create a custom .ewem file.

I really want more customization options, but unfortunately Psyonix and Epic don’t seem to let us customize much anymore.

Any info or ideas would be appreciated.

I've been wanting to change up the maps a bit because they have gotten a bit boring but as far as i can tell, there isnt a way to have custom scenes, only in training or private custom game.

Hey all. Today I wanted to try and set up a custom player anthem for my game. I followed a couple older tutorials on Reddit. Edited the song, converted it with Wwise, and swapped it into the game files, but I just got silence. I tried swapping other song IDs too but those didn't even go silent. Apparently Psyonix added a new layer of encryption that makes custom anthems pretty much impossible to do now.

I wanted to post about this to know if anybody had a solution, or at least knew of something being worked on.

I recently installed Bakkes Mod, Alpha Console, and tried to add a decal, but every file is a DDS. I'm not sure how to get those to work, do any of you guys know how to import them?

Plus qu'une immersion, une possibilité d'enrichir notre gameplay...

Traces de dérapages. Gerbes de terres. Éclaboussures ou mottes qui volent à l’impact d’un plan B… Ou encore des zones devenues si accidentées qu’elles en deviendraient plus difficiles à appréhender ?

Une empreinte visuelle unique pour chaque match qui pourraient, à l'avenir, conduire à une adaptation tactique…

Qu’en dites-vous ?! Des dev de chez Psyonix dans le coin pour faire germer l'idée?
