Interior Photorealism — Complete Prompt Library
All prompts for converting 3D interior models and SketchUp exports into photorealistic renders. Covers full rooms, wide shots, furniture, macro and micro detail. Two hard rules apply to every prompt.
1
No modifications to the input
Do not change, add, or remove any geometry, furniture, object, or spatial layout from the uploaded model or image. The input is the ground truth.
2
Fixture-only artificial light
Only generate artificial light where a visible light fixture — lamp, pendant, ceiling fixture, wall sconce — is present in the uploaded image. No fixture visible = no artificial light.

Workflow Notes — Nano Banana Pro
Strength Setting
Keep img2img strength at 0.45–0.65 to preserve SketchUp geometry. Higher = composition loss.
Fixture-Only Light
No fixture in the source image = no artificial light in the render. Daylight or ambient only.
No Added Objects
Avoid "add", "place", "include". Describe what exists, never what to insert.
Negative Prompt Stack
Always pair with: cartoon, illustration, added furniture, extra objects, lens flare, oversaturation, HDR, plastic.
Macro / Micro Shots
Crop and mask the target area before generating. A tight input gives sharper material results.
Material Specificity
"Quarter-sawn white oak" beats "wood". Specific material names = better realism.
