One Model X template, and nineteen panels — the same count as the Model S, and far more than the Model 3. Pick it by name rather than by resemblance: the Model X and the Model S share a panel count but not a layout, so a design carried across from one to the other will not sit where you placed it.
One template covers every trim of this model.
Panel counts are read from each template's own zone map. More panels means more of the body can be coloured separately; the Cybertruck's five are the whole body, which is why intricate designs do not read well on it.
