Cowbots and Aliens: the Saloon Paintings

Last year I worked on a game called Cowbots and Aliens; it’s a Virtual Reality Sci-fi/Western mashup on STEAM VR by Wizard Games.  It was a lot of fun designing the characters for this game (I will be adding a separate post about that).  The pictures above are paintings I made to appear on the saloon walls (the frames were added in Photoshop to allude to the way they appear in game).

So many Westerns have a reclining nude above the bar in the saloon, so I made the first image as a parody of Manet’s Olympia featuring the characters from the game.  The two portraits are inspired by Victorian-era paintings and photographs with all their pomp and seriousness.  The landscape is a parody of that genre painting of the lone cowboy out on the landscape.  He’s riding a rocket-powered hobby horse – a feature we were planning to add as an additional way of motion to satisfy some gamer’s wishes.

One fun feature about the paintings in the game is that you can take them down off the walls and use them as a weapon or shield.

Planes

Here are some story panels I did for Disney’s Planes in 2013.  The process for these was to take the 3D character models in Maya, light and render them and create the simple 3D backgrounds. The main portion of this task was combining all the elements and creating a digital painting in Photoshop.  One of the challenges for these was to make sure the planes are always positioned so you can see their mouths -so you can read their expressions.  This task was much easier on Cars as their mouths are right at the front.  With Planes, the long fuselages presented a challenge.

Thoughts on Painting Clouds

Clouds have to be one of my favourite things to look at.  They are constantly changing, come in many forms and have an element of mystery to them.  I find clouds to be one of the more challenging things to paint for a variety of reasons.  I’ll try to explain some of these challenges and discuss observations I have made.

A little history: Until the nineteenth century, they were all just called “essences” as nobody thought to classify or name the different types.  In 1802, a 30-year-old amateur meteorologist, Luke Howard, decided to categorize and name them.  He presented his findings to the Askesian Society in London, his work was accepted and is what we still use today.

This post won’t get too far into the science that describes clouds, but I believe it is important to know about the basic cloud types in order to paint them well.  The illustration below depicts the most common cloud types at their relative altitudes. (I have seen paintings that depict high altitude clouds placed too low in the scene.  It’s all right if you want to do this for a certain effect, but if you are doing it accidentally, it can look really silly).   I chose to paint this without colour to focus on the forms.

Cloud Types
The main cloud types as first described in 1802.

 

Usually, when I draw or paint I use a technique called the “Form Principle.” The Form Principle is a way of representing the way light and shadows fall on objects.  This works well for painting solid objects as you think of the shape of the object you want to represent, then decide where the light source is.  This principle will guide you as to where you put your light and shadows. Unfortunately, this technique has only limited success when painting clouds.  The problem with this is you wind up with clouds that look solid – like lumps of plaster floating in the sky.

FormPrinciple_Materials

In the illustration above, I’m attempting to show how the properties of the material interact with light in different ways.  For example, illustration three shows how the form principle still applies to a very shiny object.  The centre light, highlights, and shadows are all in the same place as in the first illustration, only the highlights are much more defined and the reflections dominate the shadows.

FormPrinciple_Glass4

Illustration four depicts a sphere that appears to be made of transparent glass.  Again, the shadows and highlights are in the same places, only the highlight that appears on the top right of the sphere passes through to re-appear on at the lower right.  Also, notice how the glass acts as a lens and brings a bright spot to the middle of the cast shadow.  Another interesting note about representing glass is how the edges of the object appear to be a little darker and slightly more opaque than the centre of the object.

FormPrinciple_Diffuse5

Illustration five depicts the same sphere as in illustration one, only under diffuse lighting conditions.  Notice how the form shadow, cast shadow, and highlights are gone.  The object is mainly shown in reflected light and only has a small occlusion shadow underneath.  The object is rendered in such a way where areas closer to and facing the viewer are brighter while more distant areas and angled away from the viewer appear darker.  This is known as ambient occlusion and is an important concept to use in drawing and painting.  I often combine directional and ambient light in my work as it makes things look more three dimensional.  Renaissance artists like Michelangelo used the ambient occlusion technique almost exclusively in their paintings to emphasize the forms of their figures.

The_Flood_Michelangelo
Michelangelo Buonarotti, The Great Flood (detail), Sistine Chapel. The Vatican, 1512. An example of ambient occlusion. Note the lack of directional light, form shadows or cast shadows.  The light is diffused and only occlusion shadows are seen.

 

FormPrinciple_Clouds6

For illustration six I have rendered this hypothetical sphere shaped cloud.  When you observe clouds, the light not only hits the surface, it penetrates and scatters inside them; it is a phenomenon called sub-surface scattering.  If you have ever put a flashlight behind your fingers and noticed the way the light makes the outer edges of your fingers glow you have experienced what subsurface scattering is. This is the key to making clouds look believable.  Notice how the highlights are broad and wrap around towards the edges of the form.  In less dense clouds, the light may pass through the form and spill into the core of the shadow area following the path of the light rays.  The area near the terminator line is often the darkest part of the shadow.

Clouds as seen from a distance often appear to have sharp, defined edges, but like our glass sphere, the edges appear slightly darker.  This phenomenon is subtle, especially when contrasted with cloudless areas in the sky, but observe how noticeable this effect is when a bright area appears behind it.

Cloud Structure:
Believe it or not, clouds do have structure.  I’ll update this post soon with some thoughts about the anatomy of clouds. Even at this point, though, you need to think about what kind of cloud it is an how its masses are formed.  The density of water droplets and/or ice crystals inside them will change the way light interacts with them.

Art From “Splurgle!”

Here are some illustrations I created for  a project called “Splurgle!”  This Leapfrog game features a raindrop named Splurgle, who needs to navigate his way through a series of pipes to get back to his lake.  My part in this project was to illustrate a series of panels that would explain ideas like volume and the processes of condensation, evaporation and freezing as Splurgle would need to change states to get through the pipes.

The idea was to create illustrations that looked like they were being shown in a classroom – as if there was a film projector showing the film on a screen.  I decided to make the illustrations look something like what you might see in those UPA Cartoons from the 1950s (this was the studio that created Mr. Magoo among many others).

I made a set of twenty-three of these in about two days.  Usually, I am called upon to do more detailed and demanding work that takes a long time to do, but this was refreshing to make something more simple and with obvious imperfections like the wonky hand drawn letters and off-register colours.

Thowback Thursday: Art Edition

In 1997, I was working for Disney Interactive.  At the time, 3D environments were a relatively new thing.  I had the task of showing what we could do with the technology we had.  I created these backgrounds using 3DStudio and Photoshop. You might be thinking 3DStudio Max, but this was earlier than that.  3DStudio was created for the DOS platform, and models were built in wireframe.  That’s right – if you wanted to see a shaded view of our work you needed to render it. Sometimes you would have problems like inverted polygons (what would look like holes in your model), but you would have no idea until you rendered (and waited) to see your work.

Another challenge in creating these backgrounds was giving them that feel that painted Disney backgrounds have. Often when artists create two-dimensional works, the goal is to make the scene “read” so the viewer can see what the artist is trying to convey.  Often this involves altering the perspective and placing objects at impossible angles. You see this effect throughout Western art before and after the discovery of linear perspective in the Rennaissance.  One artist’s work that comes to mind is Edgar Degas.

The Dance Class: Edgar Degas, 1874.

Degas often tilted the floor in his paintings – often at extreme angles.  It’s not unique to just paintings, though. The English theatre started sloping their stage floors upwards away from the audience as far back as the middle ages; a “raked stage”.

The two backgrounds shown here were built this way, where the floor is tilted close to thirty degrees, the buildings, columns and towers are tilted back from the viewer at the top and there are few if any straight lines.  It wasn’t enough to give the camera a wide angle lens, everything needed to be considered.  The only drawback to creating art this way is that the illusion only works from the front view.  If you start to move around the scene or look at things from the side-view the illusion falls apart.  I remember after having completed these backgrounds the art director saying “These are great!  Can we animate a fly through?”
