Make a decal
Build transparent racing stickers from text or your own logo in the Decal Studio. Curve them, outline them, download a PNG. No car needed.
Build a button box
Draw a button box to the millimetre, with holes for the switches and encoders you actually own and a lid that screws on. Download two STL files to print. No CAD needed.
Drag it on the car to move it. Shift+drag or Shift+wheel resizes, Alt+drag rotates.
Arrow keys nudge · Del removes · Ctrl+D duplicates
Import a car to start.
Paint
A transparent PNG of the panels and their edges, at the skin's own size, to draw over in Photoshop or Gimp. For a shaded sheet you can paint on here, start from "Get a template" instead.
Painted it already? Hand it back here and you get the finished folder, with the DDS the game reads, ready to drop into content/cars.
