What are you working on?

I have to agree that just dealing with simple triangles using indices is very nice and... well, simple. And efficient when verts are reused.

For organic models, triangles are much better. When animating, it's almost impossible for all four vertices of their quads to keep aligned, because frame interpolation can move them around in unpredictable ways. Modeling with triangles, you can at least know if the pair of triangles that forms a quad will bend inwards or outwards when animating.

When learning to model Fightoon's models, I've spent countless hours just swapping triangles around with Ctrl+E in Milkshape to make sure they would animate correctly. Including triangles that formed perfectly flat quads while in the editor, because many times they would get shaded incorrectly when actually running the game.

Quads are good for models that doesn't animate, and for mechanic models whose parts just moves around instead of deforming.

since when has milkshape supported quads?

[mankrip]

Never. What I mentioned are pairs of triangles aligned like quads. Frame interpolation can often change that alignment during actual game play. And even if you use an editor that supports quads, no game engine actually supports them. Since all quads will be converted into triangles anyway, it's better to edit them directly as triangles, so we can choose which vertices will be used for each triangle.

I should mention the engine i'm modeling her for is UnrealEngine2

I also recently figured out a workaround to export animations for it! I can FINALLY fix those stupid driving animations, as well as making character specific taunt animations, and maybe (if i'm lucky), adjust skeletal proportions!!

working in quads for game dev isnt bad if you ask me. you just have to know the specific places where the quads dont do what they should and connect the vertices so that they do what you're wanting. working in quads for me is a bit cleaner and easier for me to see what i'm doing i started off in milkshape and doing everything in triangles is a bit cluttered.

[mankrip]

Quads are good for weapons, vehicles, and stuff like that.

However, depending on the renderer, there's another limitation: Quake's software renderer doesn't support perspective correction on MDL models, so you get weird texturing on trapezoid "quads" like the ones in the regular shotgun. Sometimes, this kind of problem can also be avoided by using triangles so you can manually map up the triangle divisions of the skin in a safer way. Sometimes, another solution is to avoid trapezoids and use square angled quads plus a few more triangles instead. But as I said, this is only required on renderers that doesn't feature perspective correction.

Only ONE more female player character to go, then it's the 11 males and that robot!

seven, I think it would look even better if you were to somehow prolong the erruption, as those are more explosions than 'splurges' of molten rock. lava generally has a fairly hard surface that takes time to seal up again before the pressure drops.
all I can really suggest is triggering a few (smaller) explosions multiple times over the course of a second or so, so long as the later bursts are weaker.

seven - Nice looking, though it could use a little more random horizontal variation, as after extended viewing it comes off as lava spark tubes rather than small eruptions. Shared it on the Facebook Quake page.

[Seven]

Yes, you are both right.
The particle effects have not yet finaly tuned.
I did this yesterday and was just too excited, that I wanted to show it

My ideas to extend it:
To what scar3crow suggested: Make 3 different effects (low/broad, medium, high/slim) and add a random call which one to spawn each time.
That should give a little variation to the visual.
To what Spike suggested: Yes, I would have to call different effectnums that use different gravity and velocity params.
I have to spend much more time on the finetuning I guess...

Another idea was to add damage to these eruptions.
I thought about how it could be done, because a particle cannot do that.
So I came to the idea to spawn an entity without model. Only give it a bbox size of the eruption.
So it is invisible but can be 'touched'.
The touch function of that entity gives the "other." approx. 10 damage. It removes itself after beeing touched, to prevent damage overflows.
After 1 second (that is the approx. time of the eruption) the entity will remove itself anyhow.

Thank you for your suggestions.
I will try to implement them.

You should at least recognize this one from MVC2 and Cannon Spike

leileilol,
This model is too cute to kill.
How can you put her into a fps game ?

[taniwha]

leileilol: next, you need a wolf
