That's a very good tutorial, more people should see this. Wow My man! You are a legend. I have been asking in every forum and discord I can find for something detailed as this. You're welcome! Thanks a lot! First things first: as the name implies, the override folder takes priority on the modules and campaign, but not on haks and saved games: hak > override > campaign > module. Well, actually it's not that simple... if there are subfolders, the priority is higher for the content with the longest path. Let's clarify: haks\subdir\*.hak > haks\*.hak > My Documents\Override > Install\Override > campaigns\YourCampaign\Level1\Level2 > campaigns\YourCampaign\Level1 > campaigns\YourCampaign > YourModule\Level1\Level2 > YourModule\Level1Dir > YourModule Also, *.hak files go to My Documents\hak folder, *.bmu to My Documents\music, *.mod to My Documents\modules. Modules shared in directory mode also go to My Documents\modules (normally, all this is explained by the builder). Now, why do you read comments about "don't use override"? The basic answer is: everything in the override directory will be used instead of any file with the same name and extension from all campaigns or modules. The good thing with this behavior is that it makes it easy to modify a creature or an item without having to change all modules that use it. On the other hand, it will also change it for modules that aren't necessarily compatible with the change. Let's take an example: the Balor whip (explanations here, fix there) was not working because of a typo in the name of the animations. In that case, it's easier to put the modified files in the override so all modules can benefit from the change. On the other hand, there are so many custom faces available that some use the same model number. In my case, I decided to renumber conflicting ones so I have the possibility to get all. But some modules use the previous number, and sometimes that leads to weird situations (hair not at the right place, descriptions not matching what you see, etc... not mentioning that it could even lead to invisible heads or creatures). Hope that helps
