Thought this would be kinda cool, if done right. I tried doing it with sprites, but it turned out horrible, and I would try it myself with models, but I can't model.

Essentially, the idea is this, in each v model, you'd make two additional models, one sort of above where your viewpoint is and one below. These models would be made to look sort of like the inside of your helmet just above and below the visor you see, this would create the effect that you actually are IN a helmet. The models shouldnt take up too much room (so it doesnt obstruct your view) but enough that you see them... here's an image of what I suggest:

Now, obviously with the right skinning (and bending it outward slightly to create the illusion of a roundish-helm) it would look much better than it currently does, but I think it would be pretty cool.

You're forgetting something:

TSA Light Armour uses a Visor, not an open face helmet.

And HA uses "Goggle"-like eye holes.

This may add immersion - but it would obstruct your veiw and be extremely hard to do... =/

Good idea, though.

Ok, Ill give you the visor and goggles, but it wouldnt obstruct it THAT much.

i think if done correctly it will look badass and we also need a clone trooper model (which ive been requesting for some time now)

I was watching the Republic Commando trailer the other day and thinking exactly the same thing...

It would be a cool idea, but it would have to be done properly, as Chrono says...

[e] the other problem would be, what happens to the model when you're building a structure? Cos it vanishes... and surely that would mean the mask would too...

hm... wasn't there a problem with transparency and sprites? 0.o (hope I got the whole context right...)

View bob would mess things up too, quite aside from the model disappearing when you build.

Billy uh... Maus you made that Low-Poly LMG, right?

I remember that in that release thread someone said the commands to disable the view bob... so... uh... 0.o

hmm

a transparent overlay in front of the eyes with a chrome efeckt
that should look like some sort of glass

edit:
and for the clone trooper chrono there are some very good ones for quake 3 or jk3 ^^
