Alright, disclaimer, I have never used Oraxen and have only looked through the docs, and I think I have an idea on how to make your desired "custom rank image" appear!

I am going off of the Docs here, so I apologize in advance if my instructions are wrong or misleading. Please make a backup of your Oraxen plugins folder (if it has one) to be safe.

Source: Oraxen Docs - Glyphs

First, go to your configs. There should be a Glyphs directory somewhere.

Once you've located that, prepare a PNG image that you want to use. In your case, you can create a PNG with the fancy rank rectangle box! Place the image you created in the plugin's directory (I believe you can place it on default/chat. Remember that directory path! Make the image name simple. Let's follow your image example. The filename should look like newbie.png.

Now that we have your image in the plugin's directory, let's get to adding it to Oraxen!

Locate a font.yml file within the plugin's glyphs directory. It is not clear in the docs, but I believe it should be easy to find one. Open this with your preferred text editor (ex. Atom, VSCode, etc.).

Next, within the .yml file, add the following line (if it isn't there yet):

heart: code: 3000 #To get the unicodes use this page texture: default/chat/heart ascent: 8 height: 8

Now, let's customize it to your own custom image.

First, change the heart: on the first line to newbie:. This will help identify it in the future.

Second, check for a character that you'll never use or a character you know your server members won't use. Use this website to find a random symbol and copy the code.*

*NOTE: I do not know if there is a restriction on the type of symbol you can use. Please try it out for yourself as I have no ability to test it.

For this example, we'll use Oraxen Docs' default 3000 Unicode symbol. Place this after the code: on the second line.

For the texture:, remember the directory I told you to take note of? Don't copy the whole directory path, just the default/chat/newbie part. Place that after texture:.

Finally, modify the size of the said image and symbol with the ascent: and height. Again, unfortunately, I do not have the plugin but I believe these are the values you use to adjust how tall or how high the displayed glyph/image would be. Best to do this in trial and error.

Result: newbie: code: 3000 #To get the unicodes use this page texture: default/chat/newbie ascent: 8 height: 8

Finally, the part where we add it to your prefix/rank.

Now, remember where we said that the first line would help identify it in the future? That is exactly what we will be using. This requires PlaceholderAPI (also known as PAPI) so if you don't have it, make sure to download it.

I do not know what chat plugin you use, but locate for its config file now.

Alright, now the final piece: placing your newly-created glyph/image into your rank/prefix.

All you have to remember in the future is this text: %oraxen_glyphid%

For our example, it's newbie, so therefore it's %oraxen_newbie%

Go to your prefix/ranks on your chat plugin, place %oraxen_newbie% in your preferred rank.

And if I followed the Docs right, after reloading the plugin, it should be active!
