Alright, popped back for a bit, but working on a school project for 32 hours straight kinda drained me. Nice to see some interest going. :]
Lemme address some things that came up....
First of all, the not fitting in bit. Yes, this critter is not what you'd normally expect to see in Fallout.

However, part of that is due to the fact that he's the guinea pig for the 3D technique that I've been trying out. And when you're in unfamiliar territory, you're bound to run into problems that quickly take the fun out of the process. So I went with something that entertained me while working on it. On the other hand, white isn't that unheard of in original Fallouts either. But that's perhaps a debate for another time, since here's the point of 3D...
...I can easily change the texture, remove add/items, etc. Like I mentioned earlier (or tried to... I forget), this texture is completely vanilla, sans dirt and similar, levels adjustment, etc.
As for the model itself, his legs are the same size, I assure you.

Maybe I oughtta try some different frames for the walking animation. I have 30 currently and picked out some by hand to get what you see here. His walk is a bit stylised as well.
Also what I find interesting... I made this guy with a bit of a beer belly and hams for legs, but seems like at this size, one needs to exaggerate more to get the effect. For example, I had to enlarge the original gun quite a bit to get it to Fallout standard. In tabletop gaming, we refer to these kind of miniatures as 'heroic' scale, i.e. enlarged weapons and prominent body features.
Lisac, for the death animations, not quite sure yet. The dropping-dead-on-the-ground should be simple enough. For some of the others, say, burst-splat-splat-splat, a texture change, probably. I think, though, for the really gory explodey ones, we might have to go 2D. But, we'll see.

If anybody can point me towards how they were originally done (Fallout Bible?), maybe I can fish out some useful info. It seems pretty obvious, but some inside info never hurt nobody.
Grayswandir, the Gone With Blastwave guys would be awesome, though I dunno if we should spend valuable time on Easter Eggs? Unless you plan to present them as something else? In any case, we'll see how fast this ends up working and if others manage to pick it up.
x'il, I have some stuff written up, but most of the actual process is still either in development, refinement or didn't happen yet.

In any case, I'm taking notes as I go, so rest assured there will be at least a guide if not a full scale tutorial.
That ought to take care of everything now... Gotta hit the hay. Hope I didn't come across as too defensive, but I'm tired as hell and kinda grouchy. In any case, I acknowledge the issues and will hopefully find some time to work on them. Thanks again for the interest and observations.
Cheers,
Oskar
