1. In the “res/traders” folder create a new folder.
2. Put all your custom trader avatars in this new folder.
3. Open the config file and where it says “traderFolderToUse” type the name of the folder you just created. It must match the name of the folder exactly. Leave out the file extension (for example, .png or .jpg), this is not needed.
4. Now, where it says “traderFolders”, create a new object with the traders names (copy-paste an existing object such as “defaultAvatars: {}”. Also name this new object to be the exact name of the folder you created.
5. Now, for each trader name key in this new object, type the exact name of the avatar file into the value that you want to be associated with that trader. Leave out extensions, as they are not needed
6. If you have modded traders then you need to add another key to the object and also add the file-name value. The key should be exactly what the mod author named the trader in their mod.

That should be all you need to do. Let me know if you still need help with it. (Oh and don’t copy-paste code from the example since the formatting is all screwed up.)

I added previews to the overview page.

Yes, the trader avatars that come with the mod can be found in the ‘res/traders’ directory of the mod.
