mudl

Hackish proof of concept model viewer for NWN Models.. mdl + having only muddled through a couple chapters of graphics book = mudl. See also the opengl branch for an openGL 3.3 (what the game uses) version.

Building

Install vcpkg - see the Getting Started section.

$ git clone --recurse-submodules https://github.com/jd28/mudl.git
$ cmake --preset=<macos|linux|windows>
$ cmake --build --preset defaul

Build the shaders macOS/Metal, Linux/OpenGL/Vulkan:

$ ./build-shaders.sh

Build the shaders windows dx11/12:

$ .\build-shaders.ps1

cd bin/
./mudl <command> <model>

where model is a model without extension: i.e. 'c_aribeth'

Usage

Model Viewer:

./mudl

Model Tools

./mudl [<command>] [<model>]

Commands
--------
    extract     Extracts a model and its corresponding textures, material, txi files (maybe)

mudl should be able to find your NWN install and user directory. If not set the env vars NWN_ROOT and NWN_USER to game installation and user home directory, respectively.

Limitations

This is limited to fairly basic models from the 1.69, which is basically all the ones that come with NWN:EE
No emitters, danglymesh, etc.
Only basic animations are supported, and from compiled models. ASCII model animations need a fix in the core library. No LERPing, screenshot below is much slower than actual.
No plt textures.. on the opengl branch there was a test that seems like it can get the layers right, but the colors are wrong
