The project has been a rollercoaster of challenges, but I feel that I have learnt more than ever. I have faced many issues such as programmes compatibility, corrupted files, not enough computer specs to run my project with the level of detail I wanted, amongst others. However, I have learnt to troubleshoot and test different ways to do the same thing until I find the most suitable solution, while also taking in consideration timeframe, budget, and minimum requirements for the project. I have also developed my skills in programmes such as Maya, Substance Painter, Nuke, After Effects, and Photoshop, and I have learnt a completely new programme to me such as Unreal Engine. I have also noticed that I am more confident when switching between programmes and learning new ones, since I now understand the logic behind the processes and terminology of 3D and VFX in general. I consider that this is a major step for me as a professional, because this career will always require the upgrading of my skills and adaptation to new technology and techniques. Overall, I think I have achieved a final outcome that has a professional level and that I will proudly include in my portfolio.
Due to limited storage in this blog, I was unable to publish weeks 5-9, so I added the rest of the process in the following pdf file. I will update this blog once the storage issue is resolved.
This week I focused on texturing in Substance Painter and testing the textures in Maya and Unreal Engine
Base & connections rock texture
For the rock texture, I mixed Substance’s pre-made rock textures, to then scale them down, orientate them vertically and lastly, I added a layer of dirt to give more variation and dimension. For the block of flats in the rock layer, I kept it a bit simpler as there is already a lot of detail in this section and I did not want to overcrowd it. Also, for the connections I added the same rock texture and some asphalt texture for the roads with stencilled road signs on top.

General city buildings, skyscrapers, & main tower textures
For the city buildings, I downloaded a texture from Substance website which already has the windows set up to increase/decrease to amount of lit windows and the intensity and colour of the lights. I could also adjust the size of the frame of the windows so they have the proper dimensions for my model. I also added an emission layer to this texture so when exporting it, I have an emission map to adjust the windows light intensity in Unreal Engine. This was actually a good discovery as I could texture all the buildings at the same time and pretty quick, whereas if I had to do the buildings one by one, it would have been time consuming and a pretty tedious job to do. For the bridges, I used another texture that I found in Substance website which resembles the texture of the circuits of a machine and, by adding an emission layer, I could show some neon lighting in the circuit details so it makes them stand out. As a final touch, I added a flying car landing sign on the top of some buildings using one of Substance pre-made stencils. I also added a purple neon glow to make it more futuristic.
For the skyscrapers, I added a simple glass texture for the windows as I am planning to add an emission effect later on in Unreal Engine. Then for the main body of the skyscrapers I used a metal texture with some scratches and a concrete texture with some dust painted on top manually. The skyscrapers textures are simple as these are not going to be too visible in the night ambient of the scene.
For the main tower, I also used the same circuit texture that I used for the bridges. In the edges, I added a glass texture with a purple colour which will be lit later on in Unreal Engine. Lastly, using a stencil and an opacity layer only, I painted some vents on the top of the tower.

City details textures
I chose a patterned texture for the city wall and metallic edges. Then I painted some dust on the lower parts so it blends in with the rocky base texture.
For the capsules, I used a glass texture for the top part and another circuit texture (different from the main tower and the bridges texture) to simulate the capsules engine.
The lamp posts and the antennas were textured really quick as they are very small and won’t be too visible. Therefore, I added a metallic and a glass texture for the lamp posts (which will have lighting added on later on in Unreal Engine), and metallic and carbon fibre textures for the antennas.
The cranes also have a metallic texture with some rusty details and a rope texture for the cable which I painted in grey so it looks like a metallic cable. The base has a concrete texture.
Lastly, the flying cars have also a basic glass texture for the windows and a basic metallic texture for the main body as these are going to be very small in the scene. The only distinctive attribute these have is the blue stripe in front which will be the car’s front light. I am also planning to add some emission effect in Unreal Engine to this front light.

This week I got a bit delayed and I only managed to do the UV maps of all the parts of the model, so I will start with the textures next week.
UV Mapping
I made the UV maps in separate sections of the model, so it is easier to texture later on on Substance Painter (the model in parts will not be as heavy to texture and the programme will run better). I used ‘camera based’ tool to detect the UV map of each part based on the camera view, then I started to cut and sew the seams of each UV to be ablate unfold them as flat as possible without overlapping UVs. Then I used the ‘optimize tool’ to straighten the UVs as much as possible (this will make texturing easier as will avoid stretching issues). Lastly, I used ‘layout’ to try to arrange all UV shells of each section in 1 UDIM, spreading to 2 UDIMS for those sections that were too big to fit in one. After all the UVs were ready, I renamed the UV sets (to avoid issues with UV overlapping later on in Substance Painter) and I exported the model by sections in USD format.
I tried to finish the overall city model this week to get it ready to start with the UV maps and texturing.
General city buildings modelling
I decided to make the general buildings of the city using some tools like ‘transform’ and ‘extrude’ to quickly generate random building shapes. I used the following tutorial as an example:
City Modelling tutorial (SYIA Studios, 2019)I created a disc and reduced the subdivisions to have a irregular gridI extruded the subdivisions to create the roads of the cityI extruded the subdivisions again but this time upwards to give some elevation to the terrainI created some more subdivisions inside the current faces of the discI extruded the smaller subdivisions to give some separation between themI used the ‘transform’ tool to give some randomness to the faces selectedI extruded the faces and, because I randomise them, these will elevate differently to create the effect of the buildings of a cityTop view of the buildings
Rocky base buildings remodelling
After modelling the city buildings, I noticed that the buildings in the rocky base were a bit off scale so I decided to remodel them and create a more cohesive design. I used the same technique that I used for the top city buildings, by randomising the faces of a cylinder and extruding them out. Then I picked a few faces I moved them inwards so it seems like entrances to the buildings or even garages for the flying cars.

For the bottom building, I tried to keep it simpler, and just extruded in the subdivisions (giving some separation between faces) and then extruded out some balconies. the bottom part has big doors as if they were entrances for big flying trucks.

Skyscrapers and bridges modelling
To give some interest and variety to the city, I also modelled some skyscrapers that will be placed in the middle section of the city. I also added some bridges linking the lower buildings of the city.

City connections/pathways, entrances, & city barrier
Using the same technique I used for the rock of the city base, I created rocky connections between cities, with two main roads and a train track in the middle.

City details
Lastly, I added the city details like lamp posts, transit capsules, flying cars, cables, antennas, billboards, and cranes, to make the city more realistic and alive. I used MASH to help with the lamp posts repetition and with the flying cars positioning and animation around the city. I did not make many billboards as most of the advertising and signage is going to be holographic. Additionally, I remodelled the roof tops of the buildings with different shapes to give some variety to the overall look.

I am a person that likes to do my projects in sections, following a logic timeline, so the work pipeline is as efficient as possible. This is why, for this project, I have decided to separate it in the following sections:
Planning
Inspiration research/Moodboards/References
Sketching/Layout draft
Modelling
UV/Texturing
Final layout/Lighting/VFX
Matte painting/Compositing/Colouring
Rendering
After deciding my work pipeline, I proceeded to organise roughly a weekly schedule on Excel to see how much time I count with to finalise this project on time:
Project schedule
Obviously, this schedule may change or may have new tasks added depending on the progress of the project and possible problems or change of plans that could arise.
Inspiration research, moodboards, & layout sketch
I did some research about floating cities to see which features I liked to add to my city and how to make the layout. I decided that I wanted my city to have a cyberpunk style with lots of neon lights which will contrast with the night sky. I also want to add some clouds and fog around the city and in between the buildings. I also liked the idea of attaching the city with ‘ropes’ or ‘chains’ to the ground (or mountains that are nearby), and include hanging vegetation from them. I also think that the contrast of a rocky and irregular terrain with the sharp and symmetric edges of the city buildings but give some interest to the composition. Moreover, I am planning to add like underground buildings that were built up in the rock as if it was built for the lower class of society (these buildings will have a more irregular shape). Regarding the neon signs, since these are going to be seen from far away, I want to make simple signs that do not have a clear language (it will only show gibberish), so the design is quicker.

After I had an idea of the style and components of the scene, I used Procreate app in my iPad to make a rough sketch of the overall scene:

Modelling city base
This first week I focused on the modelling of the rocky base of the city with the addition of the inner buildings carved in the rock. First, I created a cylinder and added a high amount of subdivisions, to then using the stamp feature of the ‘sculpt tool’, create big stalactites hanging on the edges of the cylinder. I formed the base by sections, intercalating a layer of rock, a plain cylinder layer and so on. Again, with the stamp tool, I also changed the shape to vertical lines stamp, and created the effect in the rock as if it was ripped off the ground. Moreover, in order to give a more asymmetric look, I also reshaped and distorted the shape of the cylinders with the ‘grab tool’ and with ‘lattice points’.

For the buildings in the rock, I first made a staircase using a stretched and scaled down cylinder and then using ‘duplicate special’ to translate the duplicates exactly on the ‘y’ and ‘z’ axes. Then, I cut the cylinder in sections (block of buildings) and integrated them with the staircases. And lastly, I added the windows and doors by adding more subdivisions using ‘edge loop’. In the sides and edges of the buildings, I also used the stamp tool to give them a rocky edge the blends in with the rocky aesthetic.

Lastly, using the ‘relax tool’, I got rid of conflicting areas where the stamp tool did not make a great job and messed up the points of the mesh.
