Publishing to the Steam Workshop
Once your mod is in a state where you are happy to release it or when you are finished with it, you can prepare it for publication to the Steam Workshop.
To do this, you should create preview images that explain and show off your mod for people browsing the Steam Workshop.
Adding preview.png
preview.png
is the main picture of your mod and decides the first impressions that people will have when they first see your mod. It is located in the same place as blocks.lua
.
Reassembly/
└── mods/
└── My New Mod/
├── blocks.lua
└── preview.png
└── <other mod stuff here>
Key requirements:
- Called
preview.png
, note the.png
file format. - In the right place (see above).
- Less than 1 MB file size.
Recommended factors:
- Square image so it looks correct.
- Big, easy to read title. Try making it out of your faction's blocks.
- Show off what makes your faction interesting. Put out your biggest, coolest ship for all the world to see.
I think that the preview.png
I made for Debaton is a good example:

Here is an example of how other preview.png
look on the popular section of the Steam Workshop:
Secondary Preview Images
Secondary preview images do not need to be in a mod's files and are uploaded directly into the Steam Workshop page.
Key requirements:
- Less than 8 MB file size each.
Recommended factors:
- Do not store these in your mod's folder so that they are not uploaded to the Steam Workshop and take up the storage space of whoever downloads it.
- Show off your ships, your weapons, anything you could not fit in the
preview.png
. - Add text to explain things, such as faction gimmicks.
Mod Description
Before you publish to the Steam Workshop, it is a good idea to prepare a mod description.
It could answer these questions:
- What is this mod?
- Does it have any gimmicks?
- What makes it special?
- How strong is this faction?
- Does it have any interesting lore?
- Who helped you make it?
Publishing to the Steam Workshop

Next, you will see a your mod's workshop page open with the following message, which can be ignored:
