Prompt
Hard-surface 3D concept render of an original sci-fi vehicle: {{vehicle}}, designed for {{purpose}}. Believable engineering: visible panel lines, vents, hinges, landing gear or suspension, wear from use and small decals made of abstract symbols, with no real brands. Materials: {{materials}}. Three-quarter front view from a slightly low angle, the vehicle filling two thirds of the frame, parked in {{environment}}. Lighting that blends studio and location: a soft key light, a crisp rim light tracing the silhouette, subtle reflections and ambient occlusion. Finish of high-end game cinematic concept art, sharp focus, physically based (PBR) materials, 16:9 widescreen framing. No text, no people, no watermark.How to use it
- Define the purpose first (cargo, rescue, exploration, racing): shape, wheels or thrusters and wear all follow from it.
- Combine two or three contrasting materials (matte paint, bare metal, rubber) so the design reads clearly.
- If the vehicle looks like a toy, add scale cues: human-sized doors, ladders or marker lights.
- Use the result as reference for modeling in Blender or another 3D tool, not as a ready-made model.
Usage example
Vehicle: a six-wheeled rover with a pressurized cab and crane arm · Purpose: hauling supplies across Martian deserts · Materials: matte white paint, safety-orange panels and anodized metal · Environment: a reddish rocky plain at sunset.

Frequently asked questions
What does “hard-surface” mean?
It is the 3D modeling term for rigid, mechanical objects (vehicles, weapons, robots) with hard surfaces, defined edges and panels. It helps steer the model away from soft or organic shapes.
Do I get a 3D model I can import?
No. The output is a 2D image that looks like a render. It works as concept design or reference for you or an artist to model later.
