Final lighting system

I've done some research on common lighting setups and how they can have different affects on the final outcome. This was done to create a logical setup for my scene as well.

I have also looked at Digital Tutors' Exterior Rendering Techniques with mental ray and 3ds Max to translate the theories to actual technical practice. Even though I am using VRay to render out my animation, the main technical elements are pretty much the same in both renderers and any technique can be easily "translated" from one rendering engine to another.

I have used a 3 point lighting setup, where I have a dominant light (orangy color, high intensity) coming from behind the gate, simulating the sun. I`ve also set a fill light in front of the gate (redish color, half the intensity of the dominant light), high up in the sky and another light (redish color, but more towards the whites) in the middle of the scene to brighten things up so the details are more visible.

Texturing

Texturing was done neither in ZBrush by actually hand painting color and texture onto the models in real-time. I painted these onto the high poly versions of the meshes, so in order to get a color map from the painting I have done, I had to bake out the texture. I've also baked out normal maps and ambient occlusion maps so I can combine these and apply them to the low-poly versions of the models'.

Texturing high poly vs low poly was a bit different. High poly had all the detail modeled into it, so the textures needed only to contain color information and ambient occlusion. But, because of the low polys limited polygon count, some details had to be created through texture information. This is very common in games, when you see certain bumps and extrusions from afar and they actually look like they are physically modeled into the object. Whereas, if you go close to that object, you can notice from an angle that it is actually a flat surface with painted on illusions of surface detail.
I wanted to practice this, hence I`ve created all of the garment models (flags and Kael'thas robe) in low poly and painted the wrinkles and folds into the texture. There are numerous ways of doing this. I`ve chosen the burn and dodge tool found within Photoshop to darken and lighten up the necessary areas to create the illusion of folds. They actually worked :) .

Without Ambient Occlusion Pass

With Ambient Occluson.

With post-work: color correction, applying glow, vignette etc.

Test renders

I have used Photoshop a lot of times to blend an Ambient Occlusion render together with the original to see how the small details look like. This is to get a glimpse of the final affect all the little cracks, nudges etc. have on the image.
Also, PS was used to adjust colors and lighting as well with the help of tools like Curves so I can get quick results right in Photoshop without rendering in 3D.

Slowly, I start adding color here and there, being very careful at this point. I want to get a good foundation upon which I build the rest of the textures. My aim is to shade the main gate structures and the building on the right, because those are the biggest objects in the scene. The shading of those will drive the shades of other elements, so I have paid extra attention here.

This is an early test render of those textures applied:

Here are some of the assets that populate the scene:

Color theory tests

In order to further my understanding on how color affects the perception of my environmental work, I started studying the book "The Color Start" by Johannes Itten.

The book goes into the fundamental basics and characteristics of each color and its affect on the viewer.
For example, some colors stir different emotions and feelings like anxiety, relaxation or danger.

Green color conjures feelings of balance, relaxation, harmony. On the opposite side, the colors of amber (yellow, orange, red) stimulate nervousness, unsettled and mixed emotions.

To put these theories to the test, I`ve decided to change the color palette of some of my earlier work.
The still images I have created in the past had specific color palettes to convey a desired mood.

I`ve decided to fundamentally alter their colors to achieve all sorts of different atmospheres and moods.

Haunted House - original image:

The original image has a cool, horror kind of feel to it. I`ve aimed for a picture with a sense of mystery and danger.

Changed:

I've tried bringing warm colors of red, yellow and orangy colors to create a calmer atmosphere.	I play around mostly with the shades of green. Green brings a sense of relaxation to the image.
This one is similar to the first version, but I wanted to experiment on how contrast affects the final outcome.	Shades of violet stimulates the viewer, conjuring imagination and bringing a sense of beauty to the image.

Old House - original image:

Colors used here are warm and soft. The aim was to create a pleasant
environment, presenting a sunny day in a rustic house.

Changed:

It is really fantastic how you can change the entire mood of an image by just adjusting the color palette. The version where I have mainly used red tones create a completely different sensation to the one where mostly bright blues play part.

Telegraph - Original image:

Tried to simulate an interior scene with a fairly sunny day outside.
There is a balance between light grey colors and orangy, brown shades
of the furniture. I have added a hint of deep red to the pen to break up
the dull orange colors a bit and add further contrast.

Changed:

Again, totally different perceptions of the image because of the color change.

I will definitely benefit from this new knowledge and will play closer attention to the colors right from the planning stage.
I will alter my workflow and implement a thorough color research to define a specific color palette before starting to delve into the technical stages. I feel this will grant me a better understanding on what I am actually creating and will bring me more confidence and control over my work.
