It’s been a while since I’ve needed a helping hand but now I am a little stumped. I downloaded some custom food icons to use in my tavern store but I cannot figure out how to import them into my module. Can anybody tell me which folder I am supposed to put them in? I’d really appreciate it. 
Assuming the new icons are simply replacements for existing ones, first import them to a .hak (using nwhak, which ships with the game) in the hak subfolder of your Neverwinter Nights documents.
Then, in the toolset, go to Module Properties > Custom Content to add the .hak to the module.
Hi, thanks for your reply but they are additional icons to buff up the food options in my module. 
I am trying to work out which folder to put them in but using custom content is really confusing for NWN1
Given the lack of detail, I can’t decide whether your need is simpler or more complex than I assumed.
If it is just for your own amusement, drop the icons in Documents\Neverwinter Nights\override. See what happens.
If your module is for distribution to others, let us know why putting them in a hak won’t work - for example, are you adding a new base item type?
