Prompt
BASE IMAGE: Use the FIRST image as the locked base image.
Camera angle, distance, perspective, and framing must not change
Environment, road, background, lighting, people, shadows, and atmosphere must remain unchanged
Only the existing car in the scene is to be replaced
REFERENCE IMAGE: Use the SECOND image as a visual reference for:
car model
body shape and proportions
color and paint finish
details (lights, trim, wheels, etc.)
Do NOT use the reference for environment, lighting, composition, or perspective.
TASK (STRICT)
Replace the existing car in the base image with a fully re-rendered car based on the reference.
Only the car changes.
The new car must be exactly aligned with the original car’s position, scale, and orientation.
The new car must sit naturally on the road, with correct shadows, reflections, and lighting.
Do not move or modify the road, background, people, or other objects.
Do not change camera angle, crop, zoom, or perspective.
INTEGRATION RULES
Re-draw the car completely — do not copy, cut, paste, or overlay pixels from the reference
Lighting must match the base image precisely
Shadows must fall naturally on the road surface
Reflections must include the environment, nearby objects, and lights
Color temperature and brightness must match the base image
Wheels must touch the road naturally
The car must look like it was originally photographed in this exact scene
NEGATIVE PROMPT / PROHIBITIONS
No camera changes
No perspective changes
No cropping or reframing
No moving or altering people, props, or environment
No scene regeneration
No stylized or CGI look
No copying pixels from the reference image
