Trained at 768px, 600 steps, AdamW8bit, cosine_with_restarts.✨ Emergent effects:<ul><li>Gradient surfaces - clouds, smoke, fog, fire, atmosphere: deep analog painterly quality, as if airbrushed on paper</li><li>Smooth surfaces - skin, plastic, metal: surface-blur-like effect, removes micro-noise and texture artifacts, evens gradients</li><li>Object edges - sharpened and stylized, more "painted" feel</li><li>Background-first - at moderate weights affects mainly background; at high weights touches subjects too</li></ul>⚠️ Side effect: Smoothing suppresses fine texture (pores, grain, fabric). Not ideal when texture detail is the goal. Workaround: generate smooth, then add noise + slight blur in Photoshop.💡 Bonus use: Pre-upscale prep - smooths surfaces and reduces artifacts for a cleaner upscale input.<hr /><h3 id="what-happened-under-the-hood">What happened under the hood</h3>This LoRA was trained on abstract gradient crops with no recognizable objects - and that turned out to be the key.The model couldn't learn any specific object, so it learned pure rendering principles: how to blend tones, transitions, and light. When applied, it rewrites the model's rendering language across all volumetric, gradient-by-nature subjects - clouds, smoke, fire - because those subjects are gradients at their core.This is a case of spontaneous feature disentanglement: an abstract dataset forced style and content to separate. The result is a universal style modifier, not a content LoRA - similar in principle to implicit style-content separation described in B-LoRA (ECCV 2024).B-LoRA paper:<a target="_blank" rel="ugc" href="https://arxiv.org/abs/2403.14572">https://arxiv.org/abs/2403.14572</a><hr /><span style="background-color:rgb(21, 21, 23);color:rgb(249, 250, 251);font-family:quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif;font-size:16px">❤️ Artificial Inspiration by DORO
