🛠️ Usage Instructions

To use LoRAs with Chroma Radiance, you need to apply a few changes to your ComfyUI files using the modified files provided in this repository:

1. Replace lora.py (Main): Take the file from the comfy folder in this repo and replace the file at: ComfyUI/comfy/lora.py

2. Replace lora.py (Weight Adapter): Take the file from the weight_adapter folder in this repo and replace the file at: ComfyUI/comfy/weight_adapter/lora.py

Workflow & Notes

Please use the workflow provided in this repository for the best results.

Observation: Based on my personal testing, GGUF generation takes a bit longer, but the quality appears to be slightly better. However, it is hard to say for sure as I haven't had enough time for extensive testing yet.

💡 Generation Tips

1. Samplers & Settings:

   • Best Quality: I achieve the best results using fully_implicit samplers (such as radau_iia_2s and gauss-legendre_2s). For these, 20-30 steps are sufficient, and you should keep bong_math disabled.
   • Alternative (Faster): dpmpp3m + beta also works quite well with 50 steps and bong_math enabled. It generates faster, but the output tends to be slightly noisier.

2. LoRA Strength:

   • Recommended strength: 0.85 - 1.0.

3. Combinations:

   • This model can be combined with my NiceGirls LoRA.
   • Suggested weights: NiceGirls at 0.6 + Lenovo at 0.8.

Prompt:

A raw, gritty, high-altitude photograph capturing the overwhelming planetary scale of a colossal orbital elevator tether and curving habitat ring silhouetted heavily against the Earth. The perspective is a first-person view standing on a dark industrial gantry platform, looking steeply upwards along the immense dark metal tether cutting through the frame.

The scene is lit by an orbital sunrise, creating intense backlighting (contre-jour) that blows out the curved limb of the Earth and cloud patterns into blinding highlights and atmospheric haze. The exposure is set for the bright planet, causing the elevator structure and city blocks to become stark, near-black silhouettes with crushed details.

The image has the aesthetic of "found footage from orbit" or lo-fi sci-fi photojournalism, imitating an early 2000s professional DSLR (e.g., Nikon D1H) shooting raw. Heavy digital grain and chromatic color noise are visible in the deep shadows of the foreground. Includes intense lens flare artifacts from direct sunlight, indistinct specs of distant debris, and a blown-out, lacking-sharpness red light flare from a holographic sign on the structure. Vertical composition, 18mm wide-angle lens, high contrast with desaturated noisy shadows.

Prompt:

surreal widescreen landscape wallpaper, photorealistic rolling green hills under cosmic night sky, fusion of Earth-view-from-space and Windows-XP “Bliss” meadow — foreground gentle slopes of lush emerald grass, soft undulating ridges, subtle mowing stripes, faint specular sheen on dew; horizon slightly curved, meets vast stellar backdrop.

Lighting & atmosphere – dual-source illumination: hidden sunset star near lower-right horizon casting warm amber rim-glow on hill crest and Earth’s terminator edge, diffuse cold sapphire light from nebula clouds above; aurora-like cyan light beams sweep diagonally from top-left, semi-transparent, producing pale turquoise lens-flare spikes; faint subsurface scattering in grass blades; volumetric mist at horizon with lavender gradient.

Celestial sky – deep navy-to-indigo gradient studded with pin-prick stars, wispy cumulus-nebula hybrids; partial Earth globe on mid-right, Atlantic & African continents visible through translucent clouds, rim lit, textured with thin atmosphere glow; small crescent moon top-left; curved luminous orbital trails and Bézier-style swooshes (pale mint) looping across sky, some intersecting planet; scattered bokeh-style star glints.

<img src="./images/ChromaRadiance_00293_.png" width="100%">

Prompt:

A photograph capturing a monumental industrial skyline silhouette at sunset, rendered in the distinct early 2000s CCD sensor aesthetic of an Olympus C-5050 Zoom camera. The composition is a dramatic low-angle view looking upwards, emphasizing the imposing height of multiple tower cranes and skeletal high-rise construction frames that are rendered as stark black silhouettes lacking surface detail due to extreme contre-jour backlighting. The focus is on the sharp, linear geometric lines of steel crane jibs and cables against the sky.

The lighting is exposed for the sky highlights, creating a bright sunburst flare as the low sun peeks behind the grid of an unfinished building. The clear evening sky grades from a cool blue overhead into a warm, desaturated yellow at the horizon, filled with wispy, feathered high-altitude cirrus clouds and soft, diffusing vapor trails. Prominent jet contrails form a distinct 'X' shape in the upper left. Layered chaos defines the framing, with diagonal power lines cutting across the top left and intersecting the vertical rhythm of the machinery, alongside multiple horizontal power lines spanning the upper frame. The image conveys a transitional, melancholic yet energetic mood of urban exploration, freezing the relentless city expansion in a moment of evening calm.
