San Francisco based CG artist Vladimir Petkovic shows us how he made his awesome steampunk scene using Maya
I will briefly go over the major steps I took while constructing Cuberia ? the Capital city of my imaginary world.
Cuberia is mainly inspired by Victorian era London, with some elements from various steampunk artworks I admire mixed in for good measure. I wanted to represent a powerful and dynamic city, which is a major epicenter of trading and political intrigue.
The main focus of this artwork is the tower, which stands at the front. The shape and design of my tower is mainly inspired by Disney Hollywood Studios - The Twilight Zone Tower of Terror
. I paid a lot of attention to the texture and intricate details that could make it compelling to look at, such as the pipes, power source etc.

The city implementation
I knew that implementing the entire city scene was going to be extremely demanding on my computer's memory. The workaround I used was to build a dozen or so unique elements and then use Maya
particle instancing. The principle is that Maya only loads the instances (a house, a tree, etc.) one time and then you are able to multiply these elements almost indefinitely, without clogging the RAM memory. I added simple expression codes that randomize y-axis rotations and scaling. This helped randomizing instances even further. Autodesk has recently simplified this process with their plugin called XGen
I had three major particle systems:
- background forest
- city elements
- island grass and ground plants
At the end, I had around 3000 architectural objects and a huge number of trees, grass and other plants. Overall poly count was over 600,000,000 polys but the scene was still manageable.
I scattered multiple particle systems on basic terrain geometry
I used the Instancer tool, which replaces each particle with a geometry instance
The city itself is a combination of houses and various industrial elements. I purposely mixed medieval with 19th century architecture and retro-futuristic elements in order to get the impression of a very old, yet advanced city that has conquered electricity.
To break the repetition I placed some unique buildings and elements such as the zeppelin, floating military vessel, the botanical garden, the city square etc:
I was aiming for an exotic and oriental atmosphere, so I used Onyx
software to create tropical trees like palms and such. The grass and ground plants are modeled in Maya.
The lighting is very basic; since it is an outdoor, daylight scene, I used a Mental Ray
physical sun and sky. I tend to do lighting using the default Lambert material, without any textures.
The three major render passes I used for this project were Beauty, Ambient Occlusion, and ZDepth.
Ambient Occlusion (contact shadows)
ZDepth (used for both, depth of field and distance fog)
Putting everything together in Photoshop
was used for:
1. Render passes compositing
2. Color corrections and contrasts
3. Adding sky and smokes
4. Chromatic Aberration effect
