3D models - A call To Arms [3d][z80][ez80]

As you might know, when creating a 3D games, models play an huge part for everything. Even if the engine is one of most important part, what is displayed is even more important.

Some idea about a 3D RPG circle around my head faster and faster with the developpement of color glib. The engine get to a point that it might be usefull for displaying vivid world and monster, in a semi-iteractives framerates

However, my skill with blender and texturing are close to zero : I can retouch some model and rigs the at least, but to create one from ground up, I fail miserably. I could tackle some texturing with the huge image:texture bank I have from ripped game, but don't expect much though.

What do I need ? Well, 3D models ranging from the main character to some monster (even if those can be ripped for testing, and replaced much much later). Ideally those should be low poly enough to be displayed, but I could handle this part (I've have several nice technique to lower poly count, so it isn't much important).

One model I would love to see is a main character. Well, to be honest, I have several idea of what he/she could look like, but I won't describe it extensively if nobody might create it

So, this lead to the main question : who feel he could create a 3D model for a fantasy based 3D RPG in low poly with texture ?

Wans't there a walrii 3d model? that seems like a good main character

u/p2 May 09, 2017, 05:58:10 PM

it had cute eyes and tusks, but the flimmers were weird...

There is another model of that walrii:

But it needs work obviously as it was a quickly made model.

Not sure how well it would work in an RPG however - plus it has no textures.

Perhaps more appropriately some classic RPG models can be made, or found for free online etc?

I'd love to help but I have absolutely 0 experience with creating textures... $:-\$

A Walrii RPG would definitively be nice. I can' t help, though.

Hmm... Given the target hardware's limitations, I take it you're expecting high-end in-game, PlayStation 1-grade models and textures?

It's been a while since I've played with Blender, but last time I did manage to create and rig basic, untextured humanoid models. I also happen to draw and I'm bored of fulfilling requests from rather single-minded fellow students.

Care to give me a description of what you're looking for? Even if my humble modelling and untried texturing skills end up not being up to the task, I could use some new ideas for doodling.

u/p2 May 10, 2017, 10:25:37 PM

then I guess I'm on the same level as u, @Jean-Baptiste Boric ^^

I guess low-poly models like the good old EmpireEarth 1 ones?

u/Jean-Baptiste Boric May 11, 2017, 07:50:06 AM

Probably, though I would rather compare with in-game Resident Evil 3. I do need to dust off Blender, I don't have any models to show (and before that, I need to draw character sheet references to model from).

u/Dream of Omnimaga May 12, 2017, 07:38:45 PM

Maybe it would be better to have some of the models use lower end graphics like Stsr Fox on the SNES too, such as if there are plane/spaceship enemies, for the sake of speed.

u/Jean-Baptiste Boric May 12, 2017, 08:16:35 PM

According to the posts I've seen, it looks like gLib can output roughly between 2500 and 5000 triangles per second, about an order of magnitude less than a typical PlayStation 1 game. A Star Fox clone running at ~20 FPS sounds doable, especially with tricks like LOD or precalculated culling. The original Crash Bandicoot trilogy could push a truly ridiculous amount of polygons per seconds with these tricks, but you'd run out of RAM pretty quickly with that approach here.

u/tr1p1ea May 13, 2017, 12:44:25 PM

Except that TM02 is talking about making an RPG - not a starfox clone.

u/TheMachine02 May 13, 2017, 02:01:18 PM

Indeed the project is more toward an RPG

Anyway, thanks for your response. I'll get a folder with art & design and send it to you (just need to find some time to do it).

For polygon count, gLib is able to push about ~8000 polygones per frame when counting backface culling, but this number lower when considering full screen rendering. (For model however, they can be detailed, triangles which doesn't appears at the screen (if they have a width a 0 for example) are culled quite early in pipeline. Vertex processing performance is around 2200 cycles / vertex lighted, so about 22000 vertex/s . With this in mind, I think model should be about 600 triangles, maybe a bit more, up to 800 triangles. Main issues will be RAM of course, but I'll take care of that don't worry about it. gLib is designed for streaming data from flash anyway.

Something I am curious about is if gLib can render scaled/rotated 2D sprites fast. Many Nintendo 64 games use 2D sprites, such as the karts and characters in Mario Kart 64, although they're usually blurry. Couldn't the characters be made out of pre-rendered 3D frames like in Donkey Kong Country and Mario Kart 64 and the rest in 3D to save speed?
