Here are some sites that I have found useful over the time of trying to dabble with the serious art of um... making... uh... 3D stuff for... er... NWN. Yeah.
NWN modding resources
Modeling tutorials
- Should add something here eventually.
Documentation
- NNW .mdl Format Description - the aim of NeverBlender is that you don't need to have headaches about this stuff, but this might still be informative.
- Custom Content Guide - Good instructions on how to get the models to show up properly in toolset and game.
Tools that might help
Blender tools
- Knife - for cutting a mesh along given plane. Might be useful for slicing tiles...
Generic modding tools
- OpenKnights - aiming to bring the NWN toolkit to non-Windows platforms.
- posix-hak - command-line HAK tool.
- TlkEdit - The best 2DA/TLK/GFF editor I've ever seen. In Java.
Blender sites
- Blender.org - The main Blender page.
