Shop Portraits
This guide will very swiftly illustrate how to update the three special shop portraits in LT maker: armory, vendor, and arena.
These portraits are not stored in the same way as standard unit portraits. Instead, to update these portraits, you must use the resources/custom_sprites directory in your project. If a custom_sprites directory does not already exist for your project, create one (make sure it’s named exactly custom_sprites).
Then, place the portrait you wish to use in this directory and name it one of the following file names to replace its respective default portrait:
arena_portrait.png
armory_portrait.png
vendor_portrait.png
Now when you set up a shop of that type in a shop event, you should see your replaced portrait.
