It is recommended that you close as many programs are possible to ensure that VX Ace does not crash. Open RPG Maker VX Ace on Steam and wait for the program to load.
Select “Manage Projects” from the “File” drop-down menu. Once you click "Manage Projects", it will likely take a few seconds to load.
Step Three IMPORTANT:
to avoid errors and crashes, make sure all of your projects that will be uploaded to Steam Cloud and Workshop are in the "RPGVXAce" sub-folder of your Documents folder.
If your files are not located here, then you should move them to this file path before doing anything in Manage Projects.
Once your projects/files are in the RPGVXAce sub-folder as mentioned above, you’ll need to upload the project to the Steam Cloud. Select your project and click “Load”. This will load up your project in the maker.
Before you can upload to the Steam Cloud, you also need to write a description and select a thumbnail. This will essentially be the featured image for your project. It must be a square 24-bit .bmp image
; otherwise, you’ll encounter errors. Please see the image below:
Next, you’ll want to select “Save on Cloud” in the bottom-left corner. Please note that anything over 200 MB - as well as encrypted games - will not upload to Steam Cloud. You can delete projects by selecting them on the list and hitting “Delete from Cloud.”
Step Eight Saving the project on Steam Cloud will take some time - anywhere from a few seconds to half a minute, depending on the file size.
Once the upload is complete, your project is now on the Cloud and you can upload to Workshop! You will see some new options in the interface.
Next, you’ll want to select the type of project (Edit/Play, Play Only, or Resources), as well as the Genre and Flavor from the drop-down menus. Please note that the Play Only option will prevent users from editing your project in the Steam version of VX Ace, but the resource folders will still be accessible.
Once these are set, you can tick the box regarding the Terms of Service (after reading them of course!).
You are then ready to upload to the Workshop! Press the “Share on Workshop” button as shown below:
As with the Steam Cloud, it will take a few moments for the project to upload (typically between 10 seconds and 1 minute). If the upload times out, an error message will appear: you may want to connect to a wired connection to ensure that the upload does not time out on Steam’s end. The larger the project and the more unstable your connection, the more likely you’ll get a timeout.
Currently, there is a 200 MB limit to all Steam Projects.
Once the upload is complete, congratulations! You’ll have a project on Steam Workshop, as well as a shiny new project webpage on Steam! You can access it from the Beta Workshop page on Steam, or from your profile.
