Merging a golf cart and a brain is a challenge. Will they even fit?
I thought to use a random 3D modeler for Android and import them as objects into Unity to drive them around or something. First step: create a 3D render. That worked fairly, well, except some of the kitchen got caught up every time. I can probably trim the excess, but I eventually abandoned creating a 3D model altogether.
It was easier, it turned out, to just measure and sketch out the final design on paper, and to scale the brain around the golf cart in such as way as to give enough room inside for people to drive it. So, that’s what I’ll do instead.
