This is my idea of customization, since Forza always lacked modifying the car’s looks, except for decals and the Forza aeros and sometimes custom body kits. Microsoft could add a new style of modifying, not requiring any licenses. They could add 3D vinyl!
You know how, for example, the Formula Drift #777 Nissan 240 SX has that crazy cut out in the hood for the engine? Or how Ken Block’s Mustang Hoonicorn V2 has those 2 turbos sticking out of the hood? Microsoft could Implement tools to allow us to make our custom mods. We could have crazy turbo sticking out of the hood or even allow us to change certain engine parts, allow us to sculpt our own body kits, maybe also having a tool to widen it! In the upgrades and tunes editor, when we add a turbo, for example, the engine won’t change how it looks. It won’t have a turbo!
The “3D VINYLS” could work like this: The editor would be the same as the livery editor, but instead of 2D shapes or logos, we could have car parts! We would select them from the menu, and place them on the car. We could also have a design editor, allowing us to shape the car part how we want! For example, there we could shape a special intake for a supercharger! Or design custom aeros for the car! Spoilers, splitters, wide body kits, made by the community! In the editor, there could be a template of the forza splitter, or forza Spoiler and simple fender flares to help us design the parts.
To add “building blocks” from which our parts will be made from, we could use basic 3D editor tools, along with smoothening tool, paint tool, a build tool, which when used, adds material. It could be found in both square shaped or semi-sphere shaped. Since Microsoft has already developed a 3D editor, they could use the programming from that and import it into the forza files and adapt it to be used.
Note: [b ]I am not a programmer! ** I do not know how difficult it will be for creating an engine to support the modifications. I don’t even know if half the stuff I wrote about is even possible, but I have hope that this feature will be able to be implemented in Forza.
