Is my Apprentice version using Mantra and how do I know it does?

So far I've found Houdini to be much more easy to use than what most people say but maybe is it only because it's sooooo logical.

I'll contribute too.

Houdini's flagship renderer is Mantra. You do have to play with the settings and figuring out methods to speed up rendering process, otherwise, it may appears to be a very slow renderer if you are not being efficient about it. Nonetheless, Mantra is a very good renderer shipped with packages.

Mantra can easily compete RenderMan, surely as far as quality goes (speed requires more tweaking). Especially recently, with all the extra features, such as caustics and global illumination; via two main methods: irradiance and ambient occlusion.

I love this idea. I'd like to see some good creative renders from the photorealistic to the artistic.

If you need some help or technical infomation on optimizing mantra and such, please read and/or contribute to the OdWiki:

http://www.odforce.net/wiki/index.php/Rendering
http://www.odforce.net/wiki/


Particularly, look at the GlobalIllumination and MantraOptimizations pages under Rendering.

Looking forward to it,
Jason

Ok, this was the last thing I completed. I already posted it on odforce a while ago.

I modeled this thing recently, although I never finished it (it's poo).

This is actually from when I was learning Houdini4 and trying to use the polygon modeling tools (which was no picnic let me tell you). The scene is nothing special as you can see, but I kinda like the way this render turned out.

Nice work on the shading!

Should the magazine be so rounded? Looks good but maybe a few more lights and samples (regarding the noise) couldn't hurt. Nice though!

Looks very nice, seperate specular pass?

DaJuice

Thanks, I do wish I had made the blending between the spiky and the smooth parts a bit more gradual.

And on the gun, yeah the magazine is crap. It's supposed to hold "plasma cells" anyways so I don't know why I modeled it like a normal, albeit rounded, rifle magazine. And what can I say, area lights are slow. ;D

As for the last pic, I can't take credit for the shader, as it was (and I guess still is) in Houdini's material library. Not sure if it has a secondary specular, but it does look like that a bit doesn't it.

very glad to have so much happening I was rendering for whole weekend but dont have anything to post yet,
I was working with L system and some geometry attached to it and it took soooo much time,
dajuice your tree is very good how didi you model it?
I am trying to achieve the same with L system and skin?!

DaJuice
11-15-2004, 07:34 AM
No L-systems, I modeled the tree in a normal fashion because I wanted it to have a very specific shape.

hi, someone might remember me. ive had a long break but now im back. here's two pics i did a while ago, trying to achieve a cartoon style, its more of a concept than anything. i have since tried to do the grass on the first pic with a noise displacement map, but i think it needs non-linear displacements or a different approach. anyway the next pics will be better, i have many unfinished scenes i want to finish and some new ideas - i just wanted to get a contribution up here for now! :shrug:

cheers

theres also a proj light faking caustics

Hey, looking good zoki. I like that head model, but I don't really see the sss.

interesting character. How many polys?

dantea

darktding, I assume that you're gonna be rigging this character? At some point, you will probably want to have the arms put down even more, perhaps like 45 degrees down to help with weighting the shoulder.
