MLB The Show 25 Stadium Sharing Guide

In MLB The Show 25, one of the most underrated creative features is the Stadium Vault system. It lets players design, share, and download custom ballparks made by the community. Whether you want a realistic MLB-style stadium or something completely wild from Stadium Creator, the sharing system makes it easy to swap designs and use them across multiple game modes.

This guide breaks down exactly how stadium sharing works, how to download and upload creations, and where you can actually use them in the game.

How the Stadium Vault Works

The Stadium Vault is the community hub for custom ballparks. It connects directly to Stadium Creator and lets players upload their builds or browse creations made by others.

To access it, you go through the main menu:

• Open the Create tab (paintbrush icon)
• Enter Stadium Creator
• Use the Vault or community browsing options

From there, you can search, preview, download, or upload stadiums depending on what you want to do.

How to Download Custom Stadiums

Downloading community stadiums is straightforward and only takes a few steps:

1. Go to the main menu and select the Create tab
2. Open Stadium Creator
3. Navigate to the Vault or Most Popular section
4. Browse available community stadiums
5. Select a stadium and load it using X (PlayStation) or A (Xbox)
6. Make edits if needed
7. Save the stadium to a local slot under My Stadiums

Once saved, the stadium becomes available for use in different game modes, depending on restrictions and compatibility.

How to Upload Your Stadium

If you’ve built something you’re proud of, sharing it with other players is just as easy:

1. Finish your stadium in Stadium Creator
2. Open the pause menu using Start/Options
3. Select Save and Upload to Vault
4. Name your stadium clearly so others can find it
5. Add a description if needed
6. Confirm upload

After uploading, your creation becomes searchable in the community Vault where other players can download and use it.

Where You Can Use Shared Stadiums

Downloaded stadiums aren’t just for decoration—they can be used in several major game modes.

Diamond Dynasty (Online Play)

In Diamond Dynasty, you can assign custom stadiums through the Manage Squad menu. However, there are restrictions:

• Stadiums must follow official dimensions and wall rules
• Modified or “illegal” stadiums can’t be used in ranked play
• Non-compliant stadiums are limited to casual or offline use

Franchise Mode

Franchise players have more flexibility:

• Go to the League tab
• Open Stadium Assignments
• Select any saved stadium as your team’s home field

This is one of the most popular ways to fully customize a franchise experience.

Road to the Show (RTTS)

In RTTS, custom stadiums can be assigned to your minor league or major league teams through the mode’s editing options. It’s a good way to keep your career mode visually fresh as you progress.

Vault Limits and Storage Rules

There are a few important limitations to keep in mind when managing stadiums:

• You can actively store and assign up to 30 stadiums locally
• There is no upgrade or expansion beyond 30 slots
• The online Vault allows roughly 50–60 saved uploads in your personal collection
• You can rotate stadiums between Vault storage and local slots whenever needed

This means you don’t need to delete creations permanently—you just manage what’s active on your console.

Practical Tips for Better Stadium Sharing

A few small habits can make the whole system easier to use:

• Use clear naming for your stadium uploads so they’re searchable
• Save a “base version” before making experimental edits
• Regularly rotate stadiums between Vault and local storage
• Check compatibility if you plan to use them in Diamond Dynasty

Players who organize their Vault early tend to avoid storage issues later on, especially once they start downloading a lot of community builds.

The Stadium Vault system in MLB The Show 25 is one of the most creative tools in the game, especially for players who enjoy customization. Whether you’re downloading realistic MLB replicas or designing your own fantasy ballpark, the sharing system makes it easy to move content between players and game modes without much friction.

Once you get used to rotating stadiums and managing your Vault, it becomes a core part of how you experience the game rather than just an extra feature.
