Eight directions, with prompts
Paste any of these into the generator, then check the result on the 3D car before exporting.
- Pumpkin field: "Orange Halloween pumpkins on a black base, one large pumpkin on the hood".
- Bat swarm: "Black car with small purple bats rising from the rear door to the roof".
- Fog and moon: "Deep purple night sky, full moon on the hood, gray fog along the lower doors".
- Graveyard silhouette: "Black base with a gray graveyard silhouette running along the beltline".
- Candy corn stripes: "Three-tone candy corn stripes over a matte black base".
- Spider web: "White spider web spreading from the front wheel arch across the door".
- Jack-o'-lantern grin: "Large carved pumpkin grin across the front bumper and hood".
- Neon haunt: "Black base with neon green ghost outlines and a glowing grid".
What survives the render
Dark bases hide panel seams, which makes Halloween forgiving. Two things still fail: fine fog detail (it turns to gray noise) and thin outlines (they vanish at 1024 px). Draw thick, keep the palette to three colors, and put the hero image on the flat hood panel.
Timing
Halloween designs are seasonal, so export early and keep the PNG — the file rules do not change, and you can re-upload the same file next year without redesigning it.
