With the Strogg invulnerability out of the way (http://www.planetquake.com/tabun/tmp/previ..._strogg_pu5.jpg), it's time to think about the other strogg powerups.

It all started as a simple modelling job, and simply applying the quake3-shader on the newly modelled powerups was the plan.
But now other possibilities are worth exploring. At this point, several things should be noted.
All strogg powerups (aside from the invul.) are embossed symbols. None of them feature any details aside from their general shape. The wings provide their Strogginess.

The options:

a) The entire model, including wings, is shaderized as the quake 3 objects are.
b) The entire model, including wings, is skinned with a texture like seen on the invulnerability wings (see link above if you don't know what that is)
c) The centerpiece of the model is shaderized like the quake 3 objects are, while the wings are skinned with the stroggish texture, colorized to match the powerup's function.

At the moment, i'm leaning towards option C myself. The exception is the invisibility, for which I would apply A.

Speak.

B: Tradition above all else, at least as far as themes go. The classical look is what helps make this mod what it is, and imo it'd be wise not to deviate from it too far.

I too feel B as being the choice to make... mostly for reasons stated in Gnam's post.

I just can't picture the centerpiece being shadered like the q3 objects... while the wings are textured all Stroggish... without it looking out of place.

EDIT: I can picture the invisibility powerup being done in the fashion of A... and it would fit the theme of the powerup... but that's up to you.

I like C, if the shader is subtle.

Otherwise, B

I'm convinced. Tekhead is right, and a grainy texture is definately more stroggish than the shaders. It is also very hard to get them subtle. Their power-uppish effect can probably be enhanced by a glow shader instead, much like the items in Quake 2 did.
The one exception will be the invisibility. It is a much more subtle shader effect than the others, and looks spiffy. There is also no viable alternative. White would not look the part, I fear. In any case, if it looks off, it can easily be changed, later.

For the rest, B it is. Soon, I shall have a proper skin for the flight, regeneration and haste.

I've also worked on slipgate powerup design for a bit:




The Regen item is pretty much done. I've always been fond of Egyptian symbology, and it can easily be given a gothic touch for utter Slipgateness. It also leaves little to the imagination, as to the function.
For flight, some kind of wing-resembling rune, or perhaps the directions-rose in the middle. I'm not sure about that one, so any ideas are as always, welcome.
The haste is sortof a lightning bolt with a runic touch. Self explanatory, I should say.
The beserk kit is a less obvious. It was based on the strength rune used in some QW mods. That is also not a definite.

The runes are not exact copies of the tech designs of which I spoke, so there won't be much of a prob there. It'll all be intuitive enough.
I'm not about to make class-related techs. If anyone else is up for it, they might be made. I really don't think that would be a good idea though. the amount of models & skins that have to be loaded is insane as it is, and another set of items that need 4 times the data, with so little to gain, would be madness imo.

You're right, Makou, a meditkit type solution would be more consistent with the rest of the classes. It would also indicate a less powerful item, which is correct.
The reason I sketched it up as a rune, is because it seems to be a magical effect, quake-magical, if you catch my drift. Then again, there's absolutely no reason to assume this, so it might as well be an adrenaline shot.
I'll sketch up a medikit-type item for it.

I personally like the right-most concept design for the Slipgate Flight power-up Tabun.  It's simplistic and immediately recognizable.

Going back to Earth's power-ups, I do realize that you're trying to avoid the WW2 theme, but I think a jet-pack would best suit Earth for a Flight power-up.  I am all for the treasures from Wolfenstein-3D representing power-ups, but at the same time, I think soley having treasures for the power-ups is a bad idea.   It'll clash with the design of Earth's armor and weaponry too much methinks.

On to the rest of my suggestions...

Invulnerability:  Spear of Destiny
Regeneration:  Cross or Chalice

Invisibility is a "toughie."  My first thoughts would be that of a cloaking device, but I know you also want to avoid the "cybertech" theme.  Might I suggest a shield or a coat-of-arms then?  Possbily even a cloak of some kind...

Haste is also a "toughie," but I have an odd suggestion for it.  How about a vial containing a yellow liquid or perhaps a needle containing yellow liquid instead?

I hope this helps you out some.

Invisibility for earth could be a 'stelthsuit' designed to be mat black like the plane.

Earth haste could be a skateboard kind of thing, with jets.

Adrenalin could be a BIG choc bar. (candy bar for the people across the water)

How about a viking helmet for beserk?

My only objection  to the B option is this; the strogg texturing works on the invulnerability because it's an actual object; a skull. However, the other powerups don't have real objects; they're essentially just 3D icons, that have to use bright colors. If you try to use realistic texturing, than you end up with "realistic" neon yellow metal texture. I think, somehow, when something is brightly colored it's much more beleivable as a light or some kind of glowing device than purple/yellow rusted metal. Thats my 2 cents.

Stepping away from the Strogg stuff... for Q1, I think that the choice for the ankh to represent regeneration is nothing short of excellent. The symbolism in it and the fact that it also fits in with the Q1 gothic-ish theme makes me think that it's the perfect choice =]

As for the others... they're nice sketches? =] (but I'm having a hard time seeing them fitting in)
