For the class project you can create any vehicle you like. You can use your own reference images to import into Blender. But if this is your first attempt at creating a game vehicle, I'd suggest following along with the provided images so that your project is similar to mine. Then try the process again with your own vehicle.

Complete your class project in these easy steps:

Watch through a video lesson
Repeat the process shown in the video (and save your work)
Move on to the next video
When you've completed the course, post your game vehicle to your class project

This is a long project and may take some time. The process of creating a 3D game vehicle has many steps. But the more you do it, the quicker and easier it will become.

And feel free to post images and screenshots of your progress as you go. It can be inspiring for others to see your work.

Have fun! I'm looking forward to seeing your finished project! :)
