How to use
Unpack
Normally the wad archives have hashes as names, but luckily I managed to find the original names in the game files. You can extract the wads with proper structure using "HSUnpack.exe" that is included in the download. The model stuff is in content_neutral\levels. The unpack tool will work with ch1 - 6 + purgatory levels. Drag and drop any wad file from these level folders and the tool will do the rest. No matter which wad you drag, all of the wads will be exported. So, make sure all the wads for that level are in the same folder and do not change their original names.
Important: For the best result when loading models try not to change the folder/file names and extensions, because some features depend on it. You can delete stuff, but leave the folder structure as it is exported by the tool.
Models
Load
Chunk: Loads a chunk file which contains a single model. There may be some chunks without model data.
Export
NUX: Exports the model to a custom binary format (.nux), intended to be loaded by Noesis. Noesis script for this format : NUX Script
Textures: Exports the textures in PNG format.
Note : Models and textures will be exported into the folder Export.
Maps
Maps are actually just a collection of chunks. I added an option to load multiple chunks at once into the scene. There is also free camera when a map is loaded. You can navigate with WASD and use shift for going faster.
Load Map option will let you choose a folder and load all the chunks in it. It will also go through subdirectories. So, if you want the whole map for example you can select the resources folder which will contain all map related models. Or you can select some subfolders inside resources to load the map in smaller sections.
Export OBJ option will be available once you load a map. It will have material references but only diffuse and normal textures will be mapped. Most 3D software should be able to load this format, but I recommend Blender personally.
Note: Loading and exporting maps can take some time.
