I'm not sure what creatue thing you are talking about.

But as far as making these things, I used;

-BSAcommander: It's a utility that unpacks all of oblivions .nif and .dds files. (.nif is the mesh/object file, and .dds is for textures)
-I used Google SketchUp to model, then imported the model into Blender with the apropriate plug-ins.
-Nifscope: Nifscope is really the most important tool. It controls where meshes find their textures in the data files (this is where hard-coding comes in) as well as all the physics and lighting information.
-Then lastly, you use the Elder Scrolls:Construction Set to put your creations into the game.

This all was very difficult to learn because there is just so much and it has to be done just that certain way. But through much trial and error, there isn't a whole lot I can't mod anymore. Once you've learned it all, it's really just patience that keeps you from making stuff.

There are a few things I'm still trying to do though. One is custom arrows. I can get them into the game, modeled with physics and everything, but ym character won't draw an arrow onto the bow and hence, no arrow gets fired, though the count goes down.

Then, I need to try making a custom bow too, that being a challenge in and of itself. But we'll get to that later.

If you guys want any links to sites for tools,readmes, or tutorials, I've got like 8 links full of em.

I'll try and get some pics up tonight of my other stuff.
