I am fairly new here at CGSociety, and wanted to "break the ice" by sharing a recent work with you guys...
A couple of months ago a client approached us with a request for realistic pterodactyls, and here was the chance to learn and put ZBrush in motion!
The mesh was modeled by my colleague Vander Zafalon, and I tweaked it in Maya to get it as simplified as possible and in proper shape to be exported to ZBrush.
At render time, it is converted to a Catmull-Clark subdivision surface. We coded a special displacement shader that is rigged to work specifically with ZBrush displacement maps, so you don't need to do all that Photoshop tweaking stuff...
ZBrush could not cope with a subdivision level that would allow me to paint this kind of detail directly on the mesh as subdivision information, so I used the bump viewer shader to paint a bump map for the high frequency details.
The shader we developed automatically takes the bump map into account - if one is provided - and renders both the displacement and bump maps as full micropolygon displacements in PRman.
The bump map took the longest time to finish. Every single line was painted one at a time using ZBrush's Deco brush. No alphas or stencils...
The color map was also painted in ZBrush. The displacement map is a 4K 16-bit TIFF file, and both the bump and color maps are 6K PSD files.
The clouds were generated with Maya fluids.
I hope you enjoy it!
Cheers!

The Stargate Atlantis episode "Adrift" called for a shot where two astronauts must jump across a gaping hole in one of the city's buildings, wrecked by an asteroid.
I designed the destruction pattern and manually added the debris, broken slabs and structural elements.]]> Wed, 30 Jan 2008 04:59:45 +0000 http://gusyamin.cgsociety.org/gallery/635055

GlaxoSmithKline comissioned us to produce a commercial that could look fun and cute, but effective enough to convey the serious effects of rotavirus infection, promoting their new vaccine by urging parents to ask their pediatricians about prevention options.

"Dr. Stork" is the central character. We designed him to evoke the image of the "old, experienced family doctor", appealing both to kids and parents in a gentle and fun way while explaining about rotavirus and the serious need to prevent it.

The Baby is a central character in this commercial, and we envisioned one that would look cute and a little mischievous as well.

This is "Redecita". She belongs with a troupe of characters who serve as mascots for Telmex - the giant communications group from Mexico. We had the challenge of converting them from their previous 2D, cartoon existence into full-blown 3D.
I was the Production Supervisor for this project. Redecita was initially modeled by Luis Elias, with final model touch-ups and adjustments by Daniel Ho and myself. I did all the final shading and lighting for the characters and the sets.]]> Thu, 08 Feb 2007 03:03:17 +0000 http://gusyamin.cgsociety.org/gallery/461183

Character for a Dannon yoghurts commercial in Brazil.
The traditional mascot for one of their products, "Danoninho", is a friendly dinosaur called Dino. In this one, he drinks a "growth formula" but turns into strange animals instead.
The "Gira-octopus" is my favorite one. I did the modeling, texturing and shading, and Alę Eschenbach helped out with the full rigging of our weird friend.

Cadbury Adams wanted a music band to be the mascots for Sparkies and their entire line of candy.

We had complete freedom to come up with the whole commercial, and I pushed it to be 3D because I loved the characters and really wanted to seem them in full 3 dimensions!

This is the mascot for Fritos, a famous snack brand from Mexico owned by Frito-Lay/Pepsi Co.
This is the first time the Mexican agency attempted to create him in 3D, and everyone was very happy with the results. ]]> Thu, 08 Feb 2007 03:00:36 +0000 http://gusyamin.cgsociety.org/gallery/461171

Dino is Danoninho´s mascot. This is a traditional brand from Dannon-Brazil.
This guy was conceived and is regularly used as a 2D/cartoon character, and about three attempts were made to turn him into 3D around the world when Dannon decided none were good enough. They decided to give it one more try and handed us the task. In the end, everyone was pretty happy with the results.

This guy has had a few names... Nowadays I simply call him "The Hero".

He was the first 3D character project handed to me at Vetor Zero. Created as a "mascot" for a big electric power company, he´s a model of the company´s workers with almost hero-like abilities.

The project was shelved before we could get to the animation, but I kept the model as my occasional "guinea-pig" for trying new facial rigging techniques and new shading models.

This version has a wholly new facial model and rig, new logos (replacing the old ones from the power company) and a few shader adjustments I keep doing in my spare time. ]]> Thu, 08 Feb 2007 02:56:45 +0000 http://gusyamin.cgsociety.org/gallery/461166

A new image of the "Hero" guy!
This one was just an exercise, trying to set him into a cool backdrop in a really "hero" action pose...]]> Thu, 08 Feb 2007 02:54:57 +0000
