[quote=“aierce, post:6671, topic:42”]So if i just make all frames + shape i should be fine?
and what are the ^ H = shapes?[/quote]
Frames form the skeleton of your vehicle, like a car halfway done being constructed - all just basic aluminum framework. In order to place most other parts you need a frame to put it on. What the frame looks like doesn’t matter, it’s all just for aesthetics to make it look nice. When you just have a basic frame, the tile shape looks like the frame itself, but when you place another part on top, it changes to look like that part instead. Ie: a frame could look like ^ or = or whatnot, and then if you put a - shaped quarterpanel on it, it’ll look like - instead and the frame will be hidden.
A basic vehicle needs a frame, some kind of seat, an engine, and a fuel source, some of which can be put on the same tile as other parts, though duplicates on the same tile usually aren’t allowed. Ie. you can’t put two quarterpanels on the same frame tile, but you could put an engine, a small gas tank, and a quarterpanel there, and the quarterpanel tile will override the others (engines and tanks have no image, they’re just there invisibly).
Examine a vehicle (e then direction) you find by the side of the road and check out its parts to get a pretty good idea of what’s possible.
To make a vehicle tile considered “indoors” it has to be surrounded center, north south east and west by roofs, quarterpanels, windshields, or doors.
