I know a lot about 3D modeling and animation, but I haven't done a project yet that puts it all together in practice. Am planning to make lots of mods for this game as a learning experience.
Searching for "HKB Blender" I couldn't find much, just old forum posts saying they couldn't find much either. I think the NIF scripts for Blender might support the format, but I haven't tried it yet. (Pretty busy now learning other things.)
When anyone does learn something, I hope you post detailed tutorials or videos. So many mod communities have a few "genius" modders who just seem to know things for mystical reasons they don't share with others. Some of those modders are professional CG artists or programmers, so it's understandable they don't have time. If you're just figuring something out for the first time, though, you should document your work in detail so that a) you can reference it yourself, you can better understand just what it is you're learning, and c) other beginners will benefit. If a pro CG artist, or even amateur multimedia artist or writer, has time, they can expand upon what you've contributed. Better to have many bad tutorials that can be developed into great ones than to have no tutorials at all. It's also good to do tutorials on making tutorials; the skills can be used at school or work, no matter what you do.
