Irrlicht Engine

My "favorite format" is a custom one, there are no existing tools to do the trick.

Thanks for your help, I will have to look at custom scene nodes then I guess.

Well I don't have such modeling resources available, but you can't be seriously suggesting that's the only way.

How does Irrlicht store/handle models and their animations internally, so I could make my own "importer"? (I guess that's a pretty broad question... but any help is appreciated)

Hmm.

This is a bit confusing. I don't understand how I can draw something that is NOT some Quake 2 model that already contains animations, etc.

Say I put in a model of an upper arm, then give it a sub-node, the lower arm. I assume you can rotate the latter hierarchically... but how would I have ...

Plenty.

So in order to draw something, I need to have a scene and a node in it? What exactly is a node? If I wanted to draw a triangle, would it have to be a node? And if I wanted to change that triangle, would I have to delete it and make a new node?

How are models and animations stored in ...

Sure, there's Hello World and all kinds of code examples floating around, but where are the tutorials that explain how Irrlicht works? It really needs a tutorial that starts from the design points, architecture, etc. of Irrlicht and doesn't dive into source code right away. I have no idea what's a ...

When exporting, hit the "Options..." button and check "Export edges", that might work.
