Installing Addons
Installing Models
To install an addon model, simple place its model, texture, and config files into:
[game root directory]/HDT/Content/Addons/
Addon folders can be arranged into whatever structure of subfolders you like; just make sure that all the files for each addon are together in the same folder.
Installing Textures
To install an addon texture, place it into:
[game root directory]/HDT/Content/Textures/
Again, subfolder structure is up to you.
