Does as the title says.
To access the card creator, use the backroom door handle.
Cards are saved to the BepInEx/plugins/IGCCExports folder.
If using a mod manager, the folder can be found by selecting "Browse profile folder" in the mod manager settings.
If using a manual install, you should know where the BepInEx folder is.
Note that IGCC creates cards for JSONLoader, so you are free to uninstall/disable IGCC when you are done creating cards.
Please remember to assign a custom prefix to the cards if you want to publish them for others to use.
Any valid portraits in the BepInEx/plugins folder (and subfolders) will be loaded as portraits.
Portraits are 114x94 pixels. Any images of different sizes will not be loaded.
If you want to use a custom portrait, just put it anywhere in the BepInEx/plugins folder.
Any file with the same name as a portrait file suffixed by _emission will be loaded as an emission map for the portrait.
