Rigging in Blender

[spaps]

Is anyone here good with 3D modelling? I've been trying to make a model of a Doritos bag where you can open the top in Blender, but I don't know enough about rigging and stuff on Blender's wiki is too confusing for me (I was actually fine until I found out that you have to use Weight Paints. No idea how the hell they work or what a vertex group is). Can anyone explain this stuff to a total n00b?

EDIT:
Said Doritos bag:

Probably something to do with quaternions. Fucking quaternions.

What flavor Doritos?

What exactly are you trying to do? Are you trying to import the model into a specific engine? Or do you want to rig and animate exclusively in Blender?

Different engines require you to do different things to the model inorder to import them and have the rig remain intact. Source's method is a little convoluted but there are tutorials inorder to import custom models into it.

This is a pretty good tutorial on the basics of rigging. But if you want to import into a specific game engine you'd have to use a game engine specific tutorial. Here's a good one for Source

Bare in mind that any tutorials to export models into a source game (be they for Half Life 2, CSS, Garry's Mod or Left 4 Dead 2) will work universally in all games, including the SFM. If you want to rig a model for another engine you'll have to look elsewhere, since they tend to do it slightly differently

Okay, thanks. Source was exactly what I was looking for.

Dude, respect the Dorits!

Well, I got it fully rigged and textured.

The textures and rigging are kind of shitty, but it's my first real model so I'm still pretty proud of myself.

Now the fun part's gonna be getting it into Source. I exported it to SMD and already it broke (slightly).
and i only now realize that i forgot to scale it to the correct source engine size

Lame ranch.
