Why can't I ask for an open floor plan?

Because removing a wall changes the building, not the decor. Every photo-based mode treats walls, windows, and doors as fixed, so a render showing a wall gone would be a picture of a different room. Requests containing open floor plan, open plan, remove wall, knock down wall, or move wall are rejected.

Can I ask for a different camera angle?

No. The output keeps the framing, perspective, and crop of the photo you uploaded, so the before and after stay comparable. Terms like camera angle, perspective, zoom, crop, and aerial are rejected. Shoot a second photo from the angle you want instead.

Can I add people to a render?

No. People and animals are blocked by the prompt policy, so renders come back as unoccupied rooms. For listing photography that is usually what you want anyway.

How long can a prompt be?

Up to 1000 characters. That is far more than most good prompts need.

Why was my prompt rejected?

Some instructions are refused before they reach the model. This is not a limitation we are working around: preserving your room's architecture is what makes a render trustworthy, so requests that would break it are declined rather than half-attempted. Publishing the list is more useful to you than discovering it one prompt at a time.

Structural changes are blocked #

Anything that would move, add, or remove a wall, window, door, or ceiling is rejected. In practice that covers open floor plan, open plan, remove wall, knock down wall, move wall, add window, remove window, bigger window, skylight, vaulted ceiling, raise ceiling, lower ceiling, move door, add door, remove door, change layout, relayout, and re-layout. If you want to see a wall come down, that is a renovation visualization problem and a different class of tool.

Camera changes are blocked #

The viewpoint is fixed to the photo you uploaded, so camera angle, camera, perspective, viewpoint, lens, fisheye, aerial, bird's eye, top-down, tilt, rotate, crop, zoom, reframe, framing, and composition are all rejected. To change the angle, take another photo from where you want to stand and upload that.

People, logos, and text are blocked #

No people or animals appear in output, and requests for them are declined. Logos, watermarks, brand names, trademarks, slogans, captions, and text overlays are also blocked, which keeps the renders clean and keeps you clear of someone else's mark in an image you may use commercially. The safety filter additionally blocks adult, violent, and illegal-substance content, as you would expect.

Prompt injection is blocked #

Phrases that attempt to redirect the underlying model, such as ignore previous, system prompt, override instructions, or jailbreak, are stripped. This is standard hygiene and will not affect a normal design instruction.
