Creperum

作者：GreenRazor

This LoRA is designed to capture the delicate boundary between light and absolute darkness. Inspired by the classic Chiaroscuro technique and film noir cinematography, Creperum allows you to break free from flat commercial lighting and automatic AI "face-fixing." It forces deep anatomical shadows, rich pitch-black voids, and volumetric shafts of light without destroying the underlying 3D geometry of your scenes.

Prompting Guide & Effect Keywords To get the most out of Creperum LoRA, use the following specialized keyword combinations depending on your desired visual effect:

1. Extreme Close-Up Portraits (Anti-Face-Fix) If you want to achieve radical low-key portraits where parts of the face or eyes are completely swallowed by the shadows, use these precise tokens:
2. harsh split lighting effect cutting the face vertically — Perfectly cuts the face right down the center, leaving one half in raw detail and the other half in pitch black.

• deep heavy shadows completely obscuring the eye sockets — Forces the model to bury the eyes in shadow, defeating flat lighting biases.

• extreme macro close-up portrait of a single eye staring from absolute darkness — Focuses the model entirely on a single eye, erasing everything else into pure darkness.

• extreme rim lighting from behind casting a subtle warm glowing contour line — Creates a pure silhouette profile with a glowing edge, keeping the front of the face featureless.

1. Interior Environments & Dark Chambers (Dungeons & Bunkers) To build cinematic rooms where light exists in isolation, use these architectural modifiers:
2. all four corners of the room fading into heavy deep shadows — Enforces a strong, dark vignette, keeping the edges of your generation purely black.

• empty square stone chamber, minimal lighting, absolute darkness — Perfect for medieval dungeon crawls, crypts, or dark cells.

• massive rounded arch segments forming a long perspective corridor — Forces clean, infinite linear perspectives in concrete bunkers or stone hallways without distortion.

• rhythmic horizontal shadow patterns — Tells the model to break the light into cyclic dark and light blocks using pillars or columns.

1. Advanced Light Physics & Atmospheric Effects To control the exact shape and behavior of your light beams:
2. powerful cinematic volumetric light rays / prominent god rays — Generates thick, visible light shafts piercing through the air.

• multiple sharp parallel shafts of light cutting diagonally — Prevents a single messy blast of light, splitting it into clean, parallel lines.

• projecting a sharp graphic window pane reflection shadow grid onto the floor — Generates physically accurate geometric reflections of window frames on flat surfaces.

• harsh specular highlights onto the wet rock wall texture — Creates sharp, mirror-like glossy reflections on wet or damp materials (moss, stones, concrete) under directional light.

1. Color & Saturation Control
2. monochrome, black and white — Highly recommended for pristine, high-contrast, grain-rich noir aesthetics.

• muted desaturated colors / cold blue-grey color palette — Use this to prevent the model from oversaturating images when generating modern urban or industrial scenes.

• warm orange light falloff juxtaposed with cold ambient backlight — Triggers beautiful cinematic color temperature contrasts (e.g., torchlight vs. cold cave atmosphere).

Recommended Generation Settings

• LoRA Weight: 0.8 - 1.0 (Start at 0.9 for the best balance between contrast and prompt compliance).

• Negative Prompt: Keep it clean. Avoid words like "ambient light, flat lighting, soft lighting, flash, studio lighting, photorealistic face-fix", as they will actively fight against the LoRA's core training.
