Watch Tower

2017-11-07 19-32-22_1_3

This was a quick test project created during the Epic Megajam for the theme ‘However vast the darkness, we must supply our own light’ – I figured that was every fire warden’s worst nightmare!

The aim of this small scene was to experiment with Houdini’s procedural mesh creation tools for the first time. The rocks and watch tower were both created using Houdini (following Game Tutors tutorials), before being imported in Unreal Engine.

Creating lush foliage was also another aim of this project, which I achieved using a mixture of vertex animation, world-aligned textures and colour lerps. I had so many requests for how I created the final shader, I wrote a full breakdown on my tutorial site.

Comet the Reindeer

For this project, I wanted to replicate a Christmas card water colour style in Unreal Engine. Below you can see my development from inspiration to the finished project:

Shader Breakdown: Fur

The fur on the stag was mimicked through a shader that pans an texture using a fresnel as a mask and then is applied as an opacity mask.

Shader Breakdown: Moss

The moss Material tessellates and offsets based on a texture mask aligned to the up axis of the object. This efficiently allows the tessellation to be localised.

By world aligning the texture to Z-up, the object can be rotated in any direction and the moss will always remain on top.

The Rut

The Rut was inspired by Scandinavian rosemaling patterns and Robert Burn’s ‘My Heart’s in the Highlands‘. With four different scenes described in the poem (mountains, valleys, forests, and lochs) I wanted to challenge myself by interpreting them at different times of day to reflect the ever-changing Scottish weather.

In an endless runner style environment, I used tools such as Volumetric Fog, Decals, Particles, Render Targets, and more in Unreal Engine to capture the feeling of Scotland.

Rose

Rose

For my honours project at University I created Rose, a mobile game built in Unreal Engine 4. Rose is an exploration based tablet game following the narrative of a brother and sister. Accompanying a research project focusing on the application of situational awareness in gameplay animations, the characters in Rose elicit reactions to their changing surroundings whilst expressing mood and personality.

Apart from the character rigs (Michael Jarberg), environment rigs (Bryan Noter) and audio (William McCarter), I created and programmed the entirety of Rose.

Situational Awareness

Rose centers around Mica Endsley’s (Chief Scientist for the United States Airforce) model of Situational Awareness, detailed below:

Endsley, M.R. 2000. Theoretical underpinnings of situation awareness: A critical review. In: M.R Endsley and D.J. Garland, eds. Situation Awareness Analysis and Measurement. Mahwah: Lawrence Erlbaum Associates. 2000, pp. 3–32.

Level 1: Perception
Without basic perception of important information, the odds of forming an incorrect picture of the situation increase dramatically.
Level 2: Comprehension
A person with Level 2 SA has been able for derive operationally relevant meaning and significance from the Level 1 data perceived.
Level 3: Projection
At the highest level of SA, the ability to forecast future situation events and dynamics (Level 3 SA) marks operators who have the highest level of understanding of the situation.

Using the three core elements of Perception, Comprehension and Projection, SA can be used to visualise the stimuli the avatar is experiencing. Thus, alongside stimuli the player can directly receive – visual, audio and haptic – the player can indirectly experience smell, taste, balance, heat etc through the reactions of the avatar.

For this project, the stimuli the avatar can react to were defined as:

The Environment (such as thunder and lightning)

04-rain

Other Characters (in this case the appearance of her brother)

01-rose

Player Agency (reacting to player input)

02-windmill

Narrative Events (moments which changed the emotional state of the avatar)

05-sunset

SA also offers the opportunity for the avatar to demonstrate their personality as it incorperates their abilities, experience, training, goals, and pre-conceptions into the decision making process.

Artistic Development

Carnation, Lily, Lily, Rose 1885-6 by John Singer Sargent 1856-1925

Rose’s artistic development was greatly inspired by John Singer Sargents, ‘Carnation, Lily, Lily, Rose’. I loved the bright colours of the piece and the young girls in the dress fed into the design of my avatar – Rose.

As I was building the entire world from scratch in seven weeks, I knew I would have to keep my designs stylized to be able to complete the project in time. This early art test set the direction for bright colours and simple well defined textures.

As Rose undergoes a journey of emotions, I built a colour key to support the transitions. Pink and white were the ‘safe’ colours, appearing in areas connected with her brother, in the flowers around the house, on the rose winding up the pagoda, and in the blossom and sky at his grave.

Dark blues and purples were to signify ‘loss’, and accentuated times when Rose was going through emotional turmoil.

The environment design also drew inspiration from architectural processes. From the beginning point on the windmill, you can always see the grave in the background so there’s a sense of destination and foreshadowing. The open environment becomes dense and closed off as Rose becomes more upset, until the end when you walk up through a valley framing your destination and the world opens up again.
