0.0 Foreword My interest in enrolling in the Beyond 3D course came from the variety of skills the course had to offer that are crucial for creating an immersive VR experience. Looking back, I realize that my initial ambitions for this course were unreal(istic) in the time-frame I had, however I am very happy that the students were given the opportunity and extra time to develop their projects. This is probably the most memorable course I have taken, and time-intensive, but I have enjoyed every minute of it. I wish I was given the opportunity to learn Maya, Z-Brush, Substance Designer/Alchemist/ Painter, and Unreal Engine 4 (UE4) in my Bachelorâ&#x20AC;&#x2122;s.

1.0 Inspiration & Concept 1.1 Preliminary Concept 1.1.1 Initial Interest

1.1.2 Initial Concept

The initial concept of my scene stemmed from

The preliminary sketch of the search and rescue scenario involved 6 main elements in the map:

two things. As a Canadian in Delft in the month of February, the first was my craving for snow. The second inspiration was a surreal image I

of Iceland (see image below). I quickly started to brainstorm a search and rescue scenario.

(4) A ship graveyard (5) An ice-breaker research ship (6) A tiny-house research station

The map was bounded by a mountain range, a steep escarpment made by the excavator, and the sea. However, it was an open world without much structure or wayfinding other than a voice recording that would give directions of what to do next. In addition, when I asked for feedback at the VR lab it was strongly recommended that I focus on only one element as this was overly ambitious for the time given. I therefore decided to narrow my scope down to the plane wreck, as it best represents the year 2020. 11

1.2 Final Concept By narrowing down my scope, I was able allocate more time to creating a more detailed scene. The two main elements became (1) the plane wreck and (2) the research boat where the character starts. It should be noted that the story was not finalized when I started modelling, but that my ideas developed

3. The player gets into the driveable boat and steers it to the lighthouse, there is massive cloud of smoke in the distance.

10. The player searches for the flight recorder. 4. Once on the shore, the player gets out of the boat and moves towards the smoke in the distance by walking in between two large mounds of snow and ice. Once the player passes the mounds, the plane crash is in full view.

during the process of producing the project. 1.2.1 VR Storyboard The map is played in the following sequence: 1. Player starts on the floating research boat off the frigid coast. 2. A voice prompt tells the player a riddle: “A plane crashes in the arctic. There are survivors, but no single person survives. Find out why. Recover the flight recorder from the cockpit. Get in the rescue boat and sail to the lighthouse.”

5. A river cuts the player’s path, where the only way to get across is by jumping on 3 floating icebergs. 6. The player follows a subtle path up to the end of the plane where a door is highlighted. 7. The player opens the aircraft door and enters the plane making the way up to the cockpit.

11. The player finds the flight recorder and the answer to the riddle is played. 1.2.2 Wayfinding The final scene has more defined limits and better wayfinding than the initial concept. Landmarks are viewed by the player in a very linear sequence, even though the map does not seem linear due to the endless sea that it is located in. An illuminated lighthouse serves as a very clear landmark, as well as the plane in the distance that has a large trail of dark smoke rising above it. A line of dark ice on the snow-covered ground also serves as a subtle “trail” that most players will instinctively follow.

8. Once the player opens the door to the cockpit, there is another audio prompt: “Seems like the flight recorder is not here. Have a look below the deck, in the cargo hold.”

9. The player then drops down to the deck below and exits at the rear cargo doors.

made of cooler tones to give a frigid feel to the environment. Warmer tones, such as reds, oranges, and yellows were used on elements to attract the playerâ&#x20AC;&#x2122;s attention. These warmaccented elements included the driveable boat, light ray of the lighthouse, text that prompts action, and objects that are interactive, such as doors, and electronics within the plane.

environment allowed for a high level of contrast between elements and their surroundings, and therefore the objects placed in the scene stand out like works in an art gallery. Elements that juxtapose one another well in the sunny snow environment are: 1. The rough dark sea and the flat white coast 2. Thick dark smoke against the light sky 3. Rough snow and dark smooth ice 4. Dynamic fire and static snow 5. Patches of rough grass in the sheets of white snow 6. The light clear exterior vs the dark smoky interior of the plane

2.0 Maya 3D Modelling The modelling for this project was done exclusively in Maya 3D and was a continuous learning process, sometimes frustrating because of crashes, file corruptions, and the discovery of better workflows and methods at a later stage. 2.1 Reference Images

2.2 Modelling Workflow My plan was to model the plane as new, and then have fun ripping it apart and destroying it. To facilitate this process, I divided the plane into 5 parts: (1) cockpit, (2) first class, (3) main section with wings, (4) end section, and (5) the tail end. I also minimized the amount of work by modelling half the plane, which I then mirrored along the long axis.

I started the process by watching a few tutorials on how to model a plane, mentioned in a later section. One of them mentioned the-blueprints. com, a database of many free technical

rectangular prisms from the fuselage. Later on this became problematic when I used the smooth tool. Because of a lack of edge loops, the window holes would be deformed and there was no clean way of adding in new edgeloops. I had to redo the process by deleting the face of where an opening would be, bridging the mesh of the interior and exterior fuselage, and adding more edge-loops to give the opening more definition. This conversion to edge-loops was time consuming as it required a lot of clean up, and the â&#x20AC;&#x153;merge verticesâ&#x20AC;? tool was used extensively. At some points deleting and inserting edge-loops would corrupt the geometry, creating double faces, or removing all faces in a section, and I had to revert to older versions and try again. While it did take time initially, the model was much cleaner at the end and I was able to save time later on.

The cockpit windows were more difficult to model because they were modelled as one mesh, not as separate elements. This required a serious amount of edge-loops to define the window frames, just enough to make the openings clear but not too many or else the windows would look as boxy as a Tesla Cybertruck even when smoothed. Once the fuselage and windows were

The blades were then smoothed and grouped as a separate element from the engine so that they can be animated with a rotation in Unreal Engine. Exterior Doors The exterior doors and cargo doors were modelled by taking the product of a Boolean difference made by the ship hull and a rounded rectangular prism. For the exterior doors, an opening was modelled in the door with a window, a large latch placed, and the interior side extruded and smoothed to give the door the look of having a locking mechanism within it.

the ability to texture it from scratch. This model included a dash control board with flight control sticks, an overhead control board, seats, and a fire extinguisher. I slightly modified this model by deleting parts of it, such as the windows, re-scaling and positioning it accurately within my plane fuselage. To fully integrate the cockpit model with my geometry, I modelled extra walls that hid the transition between both models. Partition Walls As I divided the plane in a haphazard way, without referring to an interior plan, I decided that the best place to put the partition walls and toilets would be at the ends of the split parts of the fuselage. This way I would mitigate any awkward space created with a toilet partitioning the airplane hull in

which were modelled in a similar way to the walls but with different proportions. Each partition wall has two toilets close to the exterior of the plane, and two centered in the core.

The doors include a bi-fold hinge, a sliding lock, a pull handle, inset panels, and several other features to add to its realism.

The airline passenger seats were modelled from reference images, with a humanoid model as a scale reference.

The overhead storage made up most of the interior of the plane and was modelled from a technical section drawing of the plane. There are two types of overhead storage: (1) the storage close to the windows of the plane and (2) storage in the center of the plane. The overhead storage was composed of several elements: the (1) storage compartments (2) lights and air vent panels, and (3) normal panels. To maximize workflow efficiency in Maya and UE4, I simplified the overhead storage into a single low-poly module. The length of the module was equal to one storage container, and the panels would be 1/3rd of 34

2.2.3 Destroying the Model Even by splitting the model into pieces that resembled a plane wreck, some realism was still missing. I knew I could batter the model up in ZBrush, however I was not sure how I could give it the look of being â&#x20AC;&#x153;rippedâ&#x20AC;? apart. I decided I would have to model these elements as I could not find a tutorial on getting the look I envisioned. After the entire fuselage was modelled, interior and exterior, I extruded thin parts of the outer shell of the model in a random branch-like shape to give the appearance that the planeâ&#x20AC;&#x2122;s metal panelling was torn apart on impact. I was not satisfied with this as it looked very 2 dimensional and flat, so I decided to have another pass of the extruded parts and moved all the vertices in random directions. This last part really did the trick and looked believable when textured! I also created circular web-perforated steel I-beams at the end of the plane sections to expose some of the inner structure that was revealed after the crash. These were 40

modelled from a primitive cylinder that was converted into a donut, divided by edgeloops, with the inner section inset, and finally smoothed. Then smaller cylinders were radially arrayed and a Boolean difference was performed to achieve the perforated look. A section of panels on the vertical stabilizer on the tail of the plane was deleted to expose rebar underneath and to give the appearance of being damaged. This was done by detaching the panels, and trimming and extruding the detached panels to give the appearance of rebar.

2.3 UV Unwrapping Unwrapping the UVs of my model was a trial and error process. I used Maya’s UV unwrapping tools extensively, however it took me several attempts of importing my model into Substance Painter to realize that my objects that I modelled separately should be combined into one mesh, their UVs need to be well unwrapped and laid out, and there cannot be any hiding duplicated or inverted faces. Even when the UVs of certain elements looked good, I still had to recreate them a couple times and sometimes also remodel the geometry because textures were not displayed well in Substance Painter. 2.4 Modelling Issues

simply subtract the shape I wanted from the fuselage, but I had to model the openings by eye. What became problematic was that the fuselage was not always planar, and sometimes deleting or creating new edge-loops caused bad geometry. This took a few days of manual cleaning but in the end made my life easier when I exported the mesh to other programs such as ZBrush and Substance Painter. The second issue was that Maya had corrupted my files on several occasions. This happened unexpectedly, without any complex operations being performed or program crashes. The files would simply not open with an “Error Line 0: Error Reading File”. I tried clearing my preferences with no success. Fortunately, Arno was able to open the corrupted files and send recovered versions, saving days of work!

The first issue I encountered was that mesh modelling in Maya is counterintuitive to what I

4.0 Material Design in Substance Designer While browsing online for tutorials on how to create realistic materials for snow, I came across a tutorial package for sale by Pure Polygons. The 12-hour tutorial set included a breakdown of how to create a high-quality snow material from scratch with many material maps in Substance Designer, how to create the snow shaders in UE4, how to model and sculpt snow clumps with several Levels-of-Detail (LODs) that can later be painted on in the landscape, and finally how to create weighted landscape materials in UE4. 4.1 Smooth Snow Texture The material design started by creating a white base for the snow with a heightmap that was generated in a cell pattern. This same cell pattern was used to create an ambient occlusion that emphasized the shadows created by the undulating surface. Blurring maps, adding noise, and using masks created realistic peaks and shiny speckles placed and scaled randomly on the snow that added to the realism. The

rough snow texture was creating craters in the snow with snow clumps inside and on the edges of the craters, as you would see in real life. The “tile sampler” tool was key to the process of identifying edges of masks and placing the snow clumps in the appropriate places. 4.3 Snowflakes The snowflakes were created as a separate material that can be added on to both snow textures by blending the shaders in UE4. The snowflakes were simply a default “starburst” shape that were deformed. The “tile sampler” tool was used 53

The mesh maps were baked with 4x4 Subsampling, and a high-poly model of the geometry was sculpted in ZBrush. Baking high-poly geometry into the texture of a lowpoly model greatly improved its quality in UE4,

The dirt generator with a white colour worked great to give the widows a frosted appearance, and the fibre glass scratches gave it a realistic damaged look.

To achieve a more realistic landscape, I painted areas around the plane and steep topography with rough snow to give it the look of an impact, and patches of ice and uncovered grass around areas that were burning.

6.3 Landscape Materials The landscape material in my scene is composed of 4 different materials: (1) soft snow, (2) rough snow, (3) ice (a shiny dark blue material) and (4) a forest ground material with grass, sticks, and leaves (which I obtained from the Pure Polygons tutorial package I 65

more to achieve the lowest LOD. A LOD group was created consisting of all three models and the threshold distances were adjusted to display the LODs correctly. Once set, one FBX file was exported from Maya and imported to UE4 without any need to setup LODs in UE4. In UE4, I created a new material using the baked maps from xNormal, however I had trouble blending it with the landscape material, so I ended up applying the rough snow landscape material to the snow clumps to solve the issue. I then created a landscape foliage brush using the snow clump asset. I gave the brush a random scaling and rotation, and made the placement point below the surface to make the clumps look like they are embedded in the snow. After the density of the brush was adjusted, I was ready to paint the landscape with snow clumps.

times, but resolved itself eventually. 3. Door Physics: This is an issue that occurs 20% of the time. When I play the level, occasionally the throwable door shoots into space. This is because it is a physics object and its collision mesh is wedged inside the plane fuselage. Sometimes when the level is played, gravity will cause the door to fall into the fuselage at an awkward position that shoots it out within a few seconds.

7.2 Concluding Remarks

7.3 Alchemist Tutorials

Despite having worked on this project for many

months, I never got bored of it and instead felt like I was getting more and more allured to it. Every program that I used in the process was a program that I have never used before enrolling in this course. The technical and visualization skills that I have learned have not only prepared me to create architectural renderings, but to visualize anything I can imagine and create an interactive environment out of it. I am confident that what I have learned in this course, especially regarding the workflow of creating an interactive experience from scratch, can be applied to many of my projects and software that I will use in the future, perhaps not even architecturally related. I am excited to go into my final graduation studio knowing that visualizing my ideas will not be a constraint anymore, instead the constraint will be the available time I have to visualize it!
