A highly realistic, film-grade model built on Flux!
Key Features in Version 2.0
- Enhanced Anatomy: Significant improvements to hands, feet, and poses for more natural and accurate results. Say goodbye to awkwardly distorted limbs!
- Improved Textures and Quality: Upgraded skin details, richer textures, and overall sharper results. Blurry images are now much rarer compared to previous versions or using LoRAs alone.
- Better Text Rendering: While still a work in progress, text generation has improved significantly. Occasional artifacts or strange symbols might still appear, but it’s much better than before.
- Expanded Dataset: A larger, more diverse dataset (1,800 images) introduces improved balance in style, lighting, and composition.
Available Checkpoint Variants:
To ensure compatibility with various workflows, the following variants are included:
- BF16
- FP8
- Quant 8 (Q8)
- Quant 4 (Q4)
- NF4
Based on my tests, Quant 8 (Q8) offers slightly better quality than FP8, delivering finer details while maintaining manageable resource requirements. However, other variants perform well too. Choose the version that best fits your setup.
Known Limitations
- NSFW Capability: This remains a weak point in this version. However, a dedicated fine-tune for NSFW content is already in progress.
- Text Rendering: While text generation is better, occasional artifacts like strange symbols or incomplete words may occur. Using T5xxl FP16 instead of FP8 significantly improves text quality.
Tips for Best Results
- Sampler: Use the DPM++ 2M sampler for smooth, consistent output.
- Steps: Aim for 30–50 steps to capture finer details without over-processing.
- Scheduler: Beta schedulers work best with this checkpoint.
Prompting Tips:
For optimal results, use concise, descriptive prompts with clearly separated phrases. While storytelling prompts can be creative, unnecessary descriptions won’t enhance the output. Focus on essential visual details for the best results.
Future Plans
The development of this fine-tune is ongoing, with upcoming updates possibly focusing on:
- Expanded NSFW capabilities.
- Enhancing edge cases like dynamic poses and complex lighting scenes.
- Improving text rendering for more readable and accurate results.
UltraReal Flux Fine-Tune v1: Overview
This was my first experiment with fine-tuning, built on my UltraReal LoRA and expanded with a larger dataset. The goal? To push realism to the next level and strike a balance between casual aesthetics and professional-quality visuals.
While not perfect, the results were promising. Hands and feet sometimes had errors but performed much better than the base Flux model. This fine-tune delivers professional-grade images with exceptional detail, realistic shadows, and lighting—making it a versatile tool for generating stunning realistic images.
Recommended Prompt Scenarios
- Vintage Oscilloscope
- Prompt: “Vintage oscilloscope prominently displayed, featuring a green cathode-ray screen with a bright sine wave signal, black circular bezel surrounding the screen secured with screws, numerous labeled knobs and switches across the front panel for adjusting focus, intensity, astigmatism, time base, and horizontal display, red and black rotary dials indicating voltage and position controls, connectors and inputs for channels labeled below the adjustment knobs, glowing green power indicator light at the bottom right, well-worn metal casing with scratches and slight discoloration, placed on a metal stand against a cluttered workshop background with books and tools partially visible, warm ambient lighting casting subtle reflections on the metallic surface, overall scene suggesting a retro industrial or laboratory setting.”
- Town Galaxy
- Prompt: “Urban street scene with silhouetted buildings on both sides, towering electrical pylons and power lines extending into the horizon, vibrant night sky filled with stars and colorful nebula in shades of blue, pink, and orange, bare tree branches framing the right side, glowing red streetlights scattered along the road, faint outlines of parked cars in the foreground, deep shadows blending into the scene, contrasting bright celestial sky with dark urban elements, outdoor setting, sharp focus on power lines and buildings, soft gradient in the background, calm and surreal atmosphere, low angle view, natural and artificial lighting combined.”
- Battlefield
- Prompt: “Desert battlefield scene, sandy terrain with sparse vegetation, heavily armored tank in the foreground, beige camouflage exterior, barrel facing left, visible turret and machinery details, distant oil fields ablaze in the background, towering flames emitting thick black smoke, dramatic contrast of orange fire and dark clouds, daytime setting with overcast light, hazy atmosphere from smoke and heat distortion, vast open landscape, intense and chaotic visual composition.”
- Snowfield
- Prompt: “Antarctic research station buried in snow, modular beige buildings partially submerged in deep snowdrifts, exposed antennas and weather instruments on the roof, satellite dish and wind vane visible, metal handrails in the foreground partially snow-covered, clear blue sky above, harsh sunlight casting sharp shadows, vast flat icy landscape in the background, minimal vegetation or structures, cold and isolated environment, pristine snow texture with ripples and reflections, remote and extreme conditions emphasized.”
- Space Walk
- Prompt: “Aerial view from a space station, astronaut drawing the word ‘Peace’ on the station surface with a marker and pointing toward Earth.”
