>> Jeffrey Yoo Warren: I'm Jeffrey Yoo Warren, Innovator in Residence at the Library of Congress, and I'm going to show you how to use lighting, textures and effects like fog to create an emotional tone in the scenes, you create. Atmosphere. If you've gone through the earlier parts of this guide, you may have a 3D model of a building or a part of a neighborhood. But in your modeling program, you might feel that the scene lacks something, that it doesn't jump out at you like a memory or a real place you could imagine yourself within. In this part of the Relational Reconstruction Toolkit, we'll be focusing on creating emotional space through lighting, weather, textures and even movement. For this part of the guide, I've worked with Alicia Renee Ball, a multidisciplinary artist and designer, to explore how to create a sense of place and space through dynamic world building for our reconstruction models. The kinds of atmospheric effects will show help to create evocative moments like in our strongest memories, the quiet of a snowstorm or the feeling of a rainy day. Lighting is the first and maybe easiest way you can give your scene some emotional tone. Think about sunrise or sunset or other times of day which stand out in your memory. Maybe an especially hot day or even a snowstorm. Simple lighting effects can be added in the Mozilla Hubs editor Spoke, like point lighting for lamps or light bulbs or ambient light or sunlight. You can even animate falling snow using a component called a particle emitter. We'll talk about this a little later. But to create more complex kinds of atmospheric effects, you'll need to use a rendering program. I used Blender, which is free and open source. For me, it's been a challenge to represent these spaces because I've found few photographs of interiors and even fewer of the people who lived and worked here. It doesn't make sense to fill these buildings with fictional people, but neither has it felt right for them to be empty. One way I've thought to give a sense of people's presence has been to evoke a sense of warmth and comfort. Wet streets, rain and fog contrast with warm indoor lights to create a sense of shelter and enclosure. And visitors have remarked that they felt physically warmer upon coming inside out of the virtual rain. I was inspired by Alicia Renee Ball's 3D design work because of her powerful use of color, texture and composition. In addition to her interest in history, identity and place. Next, she'll show some of the ways she's incorporated more advanced atmospheric effects into a scene in Blender. >> Alicia Renee Ball: Hi, my name is Alicia and I'm going to demonstrate how I used Blender to world build digital environments. I've chosen to use a 3D model that I created through a technique known as photogrammetry for this portion of the guide. If you would like to know more about this technique for making 3D models, please see the notes written in our guide. This model is a reconstruction of a big timber log cabin found at the historic site New Echota. Before forced removal by the U.S. government, new Echota was the capital of the Cherokee Nation in the early 19th century in the state of Georgia. This area of Georgia is the home of the Koasati, Miccosukee, Yuchi and Cherokee Indigenous Peoples. I've been studying the histories of Black people who lived under enslavement in this area and who later would be known as the Cherokee Freedmen following the Civil War. Their stories are a part of the complex history of this place. And this cabin shares some similarities with what their homes may have looked like. For me, this provides a partial glimpse of how they might have lived during this era and is a part of my journey to learn more about their lives. As you see from my model, it is already skinned with a texture from the photogrammetry process. Then I'm going to create a landscape for the log cabin to sit upon by adding a plane and using it as our ground. I wanted to add depth and dimension to the ground plane instead of leaving it flat. This will help us to create a dynamic sense of place that mimics the variety of landscapes found in the natural world. As I created height and depth on my surface plane, I made sure to examine it from all directions, tweaking it until it felt and looked just right. Next to bring to life the digital environment I am building, I will be adding in a skydome to naturally light up our scene. Although it was midday, clear and sunny when I first visited New Echota to capture the footage of the log cabin from my reconstruction model, I wanted to create an environment that would evoke more emotion and a sublime sense of mystery. To do that, I decided to set my scene at sunset. Now I will pick a texture material that will best represent from memory the texture of the ground at the historical site. I'm utilizing texture maps from a subscription based service called Polygon. For your worldbuilding exploration, you can find free textures and HDRIs to use through a simple web search. From this point on, I will be worldbuilding through what I describe as the speculative imagine. How can I reimagine and rebuild parts of a real place that will evoke more emotion and a deeper connection to its histories? For me as an experimental artist and designer, I do this through playing with Mood. To help me build a more expansive world, I will experiment with mood building through lighting, color and movement. To do this, I have imported additional models into the scene to better flesh out the environment. The 3D models I'm currently using, I have downloaded from Polygon. Again, for your world building reconstructions, you can find a plethora of free CAD resources online. Pick the models that will best speak to the world you are building and reconstructing. So as you can see, I imported a few tree stumps, a chopped log and a living tree. These items are in dialogue with one another, showcasing the various stages of life, death and transition through the use of natural resources to sustain a modern world. From living trees to chopped tree stumps in transition to a log cabin. Creating a narrative or working poetically in the digital environment she build also adds to the dynamism and emotion of place and space. To create more spatial depth in the scene, I have imported a horizontal image of barren trees with a transparent background to serve as our backdrop. This imagery of barren trees creates a sense of coldness in our built digital environment because it reminds us of the transition between seasons from summer to fall and from winter to spring. Now I want to explore how the use of moving light particles can add an ethereal, dreamly and otherworldly aspect to our environment. I will explore this concept through creating an animation of sauntering fireflies that will dance, float and flutter throughout the scene. We will create these dancing fireflies through the use of a particle system in Blender. We will use our ground plane as the source that will generate the tiny orbs of light and then we will animate it through the use of a physics system called Boids. Particle emitters can also be used to create rain or snow in a scene. If you want to know more about how to create a particle system like we did in Blender, please see the notes in our written guide. We decided to use the Boid system to simulate the flight and the flutter of the fireflies, whose blooming light will add further ambience to the scene. The Boid system generates a natural flight trajectory for our fireflies. Finally to turn up the drama, mood and mystery in this scene, we will also explore important atmospheric fog into our environment. Now I will tweak the settings to increase the density, depth, visibility and color of the fog to create varying moods for our speculative scene of new Echota. In my art practice, I enjoy infusing cosmic drama into the worlds that I build. And I do this mostly through overlaying and merging of colors. This creates a hazy environment of floating auras that coat our sky and changes the dynamic of the scene depending on the density level of the fog. Here is the end result of my speculative play. And another way you can create emotional space in the worldbuilding development of your relational reconstructions. Thank you. >> Jeffrey Yoo Warren: That wraps up this tutorial.
