My original idea was to make a cinematic trailer featuring the cars I mentioned in my planning however, due to spending too much time making the cars I decided I had to change my idea as learning cinematics could prove hard and therefore, I ditched the idea. I then moved to my second idea which was to create an open city with moving cars using the cars from the cinematic trailer as I thought creating AI cars would be easy as I have done humanoid AI’s however, after a week I was deeply mistaken and as I had even more limited time than what I had I to mash up what I had. Which lead me to my final idea which was to make a simple racer which will allow me to clutch the deadline in the neck of time.

However, you can break down all my ideas with the basic list

• Mustang and MX5 as my main cars.
• Cel shading. This is mostly cause of how much I love the artstyle.
• Lighting. This is important for the world to look nice.

These are my top 3 main things I wanted to feature within my projects. Therefore, the concept and ground work was mostly the same. For each it was a matter of how well I could handle my time management.

Below you will be able to find my journal of what I have been doing. My fails on the above ideas and how I got the results I did.

Blender

Sky

To create the Sky I used 2 things which helped me get the results I wanted. This is because finding original anime skies are hard to find and therefore, I had to turn a realistic HDR into an anime sky.

The first resource I used a tutorial done by Comfee Mug. They went very in depth into what I needed to do and why I needed to do it. This helped me understand how to do an anime sky and the fundamentals to making anything from realism to anime. Such as using nodes such as color ramps to create contrasts within the model.

I then used a site called Poly Haven which allowed me to find a sky that I wanted to use. I used the same one as the one in the video this is because I didn’t want to do many changes and believed that it would be good enough for me.

The licensing is classed as CC0 which means it is public domain and you can use the raw file for all purposes, all without asking permission. Can not be trademarked by anyone.

Here is the finished product of what I made imported into Unreal Engine 5. This was a simple process however, later I will have to play with the lighting this is because the default Unreal Engine lighting isn’t great for this sky.

MX5

Making a YouTube Car

This is the tutorial I am using in order to create my car . This is because the final results they got is what I want to achieve. I decided to do the car from the video this is because it would let me get a understanding of the method they used.

Part 1

In part 1 we was laying out the references. They did it in away I have never thought of doing before. What happens is it is a plane that you put the image on you then cut it where you want it spit then parent it and position it to the reference. This is amazing as now you don’t have over sized images and makes it a little easier to follow.

Part 2

Part 3

In part 3 we covered how modeling the Front Bumper, air intake and details and creating turn signal cutouts. I felt unsure however, the positive feedback I got early on from Josh motivated me to keep going and not start from scratch. The hardest thing to do within the modelling process right now is the indents and adding small touches which has always been a weakness of mine however, in this model I feel like I am improving slowly. You can see it is coming along nicely but does lack a little bit of the small details this is something I am working on getting better at.

Part 4

In part 4 we worked on the windshield & Glass. This was the shortest part so far and overall I think I am doing very well with the tutorial series. Mine is a little less detailed and more jagged than his however, for a first attempt at a new method I am doing very well. I have also learned a few new techniques. I feel like I need to play with some vertices in order to best make it look better.

Part 5

In part 5 we worked on the Soft Top & Windows and now it is really coming together. My main goal isn’t to go 1:1 but instead to get it to look very similar. So far this is good but I need to play with it which I still haven’t done this is because I am worried I would break the model therefore, I have now created a back up and should be able to modify it without worry.

Tweaks

I created a backup project and decided to make some noticeable changes such as the grill is no more acute to the model. I also removed duplicated vertices this helped a lot in managing the topology. There is still room for topology improvements. However. this is coming along nicely. I also made the light more pronounced. I now feel ready to do Part 6. I have also decided that I don’t want to do the pop up lights that is a key feature of the car this is because on a time crunch there is no point adding details which don’t matter too much. I enjoyed doing these tweaks because it wasn’t part of the video and was nice to have a small break.

Part 6

I resumed the tutorials and we focused on the doors & side body. However, I did run into a little issue which was my mirror modifier not applying properly. To overcome this I just place it by hand which gave me more control over where the rear wheel fender. I feel very uncertain about the side coming along this is because theirs is much more smoother than mine. I don’t know how to feel about it cause well… There is a huge difference but I think I might keep it so I understand the method then I will work on it again maybe after mustang. However, that is very time consuming and will be the last of my priorities.

This is the most liked post so far for the MX5 this liking has made me more wanting to carry on with this car due to the positive feedback however, the edges are a bit harsh to me so I want to smoother them out some more.

Part 7

So I did some refining on the sides as feedback from both myself said it looked too lumpy on the side to fix this I added a sub division modifier. This has a lot of vertices as it is and that the sub division is X2 there is going to be a lot of geometry. I feel like there needs to be more attention to deal and to optimise the amount of vertices on the mesh. In this part we spent a long time refining the side as well as adding the door handle. Part 7 was mostly a 2nd segment of part 6 however, this was good as I think the pacing of the videos are amazing. This is honestly breath taking on how this is coming together.

Here is a wireframe view as you can tell it is mostly made of quads which allows better topology however, there are way to many varices to manage so when the sub division is applied by 2 then it will be very dense. This is NOT how it looks in the tutorial as his wireframe is minimal but I added more cuts to give more control to the mesh but in reality it has made it much hard to work with. I feel like I need to have a play with it before it gets too late to make it match the blueprint the best as I can.

Part 8

In part 8 we worked on the rear fender, trunk & taillights which turned out alright this took a long time to get right as I realised that my topology was getting too different to the tutorials making it harder to follow step by step. However, putting that aside it is coming on well. I am now approaching the half way mark and this is worth it. I have scanned a lot of it and he makes a higher poly version of this soon. However, I will not be wanting this as I don’t think that it is needed for the project I want to create. I also do not want the pop up headlights as they won’t be need for the trailer therefore, if I don’t need it then I won’t make it.

Part 9

I have now reached the half way point rear bumper & undercarriage are now complete. Although there are imperfections and things that don’t look right to me in this model this is something that I am proud of. My topology still sucks but I think I will amend it once the car has been made to the best I can do it. This is important to do as I plan on UV wrapping the model this is because it will benefit it in the cel shader. As I hope to get a physical based cel shader to work.

Part 10 + Tweaks 2

I decided to do some tweaking to the wireframe at this stage. This is because I felt the wireframe was too dense and was making it hard to work with. I then decided to cary on with the tutorials which now added the mirror and antena. It is coming along nicly however, there are still a lot of inperfections which it part of the learning process.

Part 11

This is where I was doing things in a rush this is because time is running short however, based on the feedback I was getting from Twitter and from friends I was doing very well.

Part 12

We are nearing the end however, out of everything I have had to model for this car I found the wheels the hardest. I don’t understand why I found them hard because in my head it was simple. But this is the final version of the car this is because if I progress any further I won’t be able to make the Mustang which I want to make.

Mustang

Ford Mustang Boss 429

After watching the YouTube video I feel like my understanding of blender and how to model has grown. I will be using the same method they did but for the Ford Mustang.

First I used Figma in order to help me scale and organize the plans this is because this was a issue when making the MX5 therefore, to prevent this I used figma. I then imported it into Blender which looked very aligned. This was something I relied when making my MX5. Though I tried to fix it I never found a decent scale to build the car on.

Road

The road was very simple to do it was just a cube which was scaled down and wide. Then with a bunch of cuts. Why cuts? Well this is because in order to get the road to deform it needs geometry so the splines can blend the mesh. The more cuts it has the smoother the transformation will be along bends whereas, less will be more sharp. This is what the mesh looks like in Unreal Engine with it’s texture as the blender preview didn’t look exiting.

https://freepbr.com/product/highway-lanes-pbr/

For the texture of my roads I decided to use PBR materials which is physically based rendering. This is often with realistic type of games. However, I believed that it would match my game.

The licensing for this is free to use unless I plan on using it these commercially. For a college project this will be fine as it is free to use with no plans on releasing it and making money from my product. However, for those who are intreased in doing it commercially there is a $16 fee which will allow you to use all PBR materials.

Unreal Engine

Map

https://freepbr.com/product/stylized-grass1/

https://freepbr.com/product/pine-forest-ground/

For my map I wanted to use a landscape that had PBR materials on them. This is because I wanted the world to feel more natural and that it the player blends into the world. This also made me learn about landscape layers this is because I wanted to hand paint the ground myself to make the world feel stylized as humans often see realism as perfect whereas, in stylized art which I mentioned in my research there is room for human error.

Now I want to do my track before painting this is because I can get a sense of scale and structure. I wanted to add elevations to the roads as well for a more styled track. I also made this track in my planning in figma. This is a great start.

AI

After doing the landscape spline method I found out that Landscape Splines are designed to modify terrain, while Spline Components are designed for positioning actors. However, recreating the map this late on meant a possibility of not finish on time. Therefore, I decided to dive into the the dark side of Unreal Engine and do C++.

https://medium.com/@werysgamestudio/unreal-engine-landscape-spline-to-spline-component-3733d97f33ee

This was inspired by a post I found on Medium which made the fundamentals to my spine system. I did also find a plugin however, it was out dated to Unreal 5.3 and was uncomeatable to 5.7 therefore, I decided to make my own. Which gave me amazing results as it is very customizable.

 I attempted some of this work myself, following the medium post  and having Claude on the side if I had any questions. Which came in handy as it was teaching me where I was going wrong and answered the questions in a easy to understand way. The reason why there are so many spline points is because of how dense I made it. I made it this dense because I wanted the AI to be as smooth as it could. This is bad for optimization but for the fact there won’t be a lot for the project optimization isn’t a huge worry.

Cel Shader

Attempt 1

I tried to use the unreal mannequin a test subject before making my own models and importing them this is because I want to create. However, this did not work well and in attempt 2 I changed my test subject. I used a material function however, it didn’t adapt to the lighting well.

Attempt 2

I decided that I wanted to add the P3 character from my research this is because it would give me a better test subject before importing my own models. This was a choice in order to try and get it as close as I can to the original product.

This is what I got for my second attempt this is slightly different from the first attempt. I decided to take a very similar approach this still uses a material function but this time it is blended between a regular material to. Which basically gets the material function + texture allowing it to be more optimised than having to redo the same function in multiple materials. In this I still think I need another version this is because it lacks in signifcant characteristics to that guilty gear has.

Attempt 3

Instead of using a material function I have decided to do it for each as the only thing that changes is the texture which allows duplicating easier. Material function also had different effects to the cel shader. This is also three banded giving it more of a anime look however, it doesn’t look as nice on the character. I feel the more I attempt the cel shader the further away I am from achieving it.

Attempt 4

For attempt 4 I decided to have a break and work on the MX5 so then I could actually have a game ready model so I could test it on. It was also at this point I began to run out of time. Therefore, I went with an easier option and used Post Process this is because it was an all round way of it being quick but good results.

I decided to use this YouTube tutorial in my final attempt this is because I was running out of time and I needed to get something done quickly. I was able to understand the tutorial and have comments which allowed me to greater my understanding of it. Post processing wasn’t the way I wanted to go however, I am pleased with the results I got and therefore I could start working on something else.

Car mechanics

I found a video which was very useful this is because it went into much depth on what I was supposed to of done and therefore, I was able to set up the car perfectly however, something felt off. It was the values so I decided to do further research into cars and how I could make my MX5 feel better.

Here is what the event graph looks like it was very simple as most relied on another plugin called chaos vehicle plugin which is great because it mean I didn’t have to do too much to it.

This lead me to discover throttle curves. Why did it make a difference? Well this is because it controls the engine’s power and speed which allowed for nice acceleration. However, 2 things still remain off which was suspension and wheels. But I decided to move on as I still have another car to do.
