Why Character, Scene and Prop Sheets Look Plain: White Backgrounds, Even Light and No Mood, on Purpose

Quick answer: A sheet is a reference: when a shot is generated, the sheets of everything in it are handed to the model as ‘this is what these look like’. The model copies what it sees — and it copies the light and the mood as faithfully as the face. A character sheet lit like a film noir poster brings that lighting into a sunny picnic; a scene plate with fog and god-rays fights the storyboard’s ‘hard noon light’ in every shot; a prop sheet on a wooden table brings the table. So sheets are deliberately neutral: characters on white with a plain side light that shows the bones, scenes as empty rooms with their layout and light source readable, props alone on white lit to show material. The cinematic look is written per shot in the storyboard, where it belongs.

Generate two clips of the same shot, once with the default neutral sheet and once with a sheet you regenerated with “dramatic lighting” in the description: the second carries that light into the shot regardless of the storyboard.

What a sheet is used for

Every clip generation receives the sheets of the characters, states, scene and props named in the shot. They are the model’s only knowledge of what these look like, and it reproduces them closely: face, clothes, materials, and whatever light and background are in the image. Consistency across a series comes from this. Same Face in Every Shot.

Why mood on a sheet is a problem

Mood is light. A sheet with a rim light, a colour cast, a smoky background or a silhouette carries those into every shot that uses it, on top of what the storyboard asks for that shot. The two fight, and the result is muddy or inconsistent from shot to shot. A neutral sheet can be lit any way the shot needs; a moody sheet can only be lit its own way.

What each kind of sheet is optimised for

Characters: full length on white, one plain side light, so the model sees the face and the build clearly; casting photo, not poster. Scenes: the empty location with three layers of depth and a visible light source, no people, no effects; a plate to shoot in. Props: the object alone on white, light only to reveal material. States: the same, changed only in the one thing the state is about. Scene Image and Description, Props.

Where the cinematic look comes from

From the storyboard: each shot names its light (source, direction, quality), its time of day, its weather, its lens. The clip is generated from that text plus the neutral sheets. The visual style chosen in Step 1 sets the medium and finish for everything. If you want a moodier film, write it into the shots, not into the sheets. Describe the Cause, Not the Result.

Uploading your own images

Your own photo works as a sheet under the same rule: a plain, well-lit picture on a simple background serves every shot; a stylised portrait serves only shots that look like it. Crop out other people and text. Your Own Reference Images.

Sheet	Kept plain	Because
Character	White, one side light, no expression drama	Face and build must read in any light
Scene	Empty, layout and light source visible, no fog or effects	Every shot in that room inherits it
Prop	Alone on white, material lit	Any hand, any table, any light later
State	As the base, plus the one change	Only the change should differ

FAQ

Can I make the sheets look cinematic anyway?

You can regenerate with mood words; expect that mood in every shot and fights with the storyboard's light.

Why is the character sheet a full-length shot?

Build and posture matter for consistency; the face is the priority within it.

Does the visual style apply to sheets?

Yes, the medium and finish; the neutrality is about light and background.

Why no people in scene plates?

They would appear in every shot of that room.

Can a prop sheet show the prop in use?

No; the hand and the setting would come along. Usage is written in the shot.

Neutral sheets, cinematic shots

The reference stays plain so every shot can be lit its own way.
