Regarding the painting problem:

The portrait has no texture, it feels very AI, and needs to be rendered. This is a portrait problem. I know that the development cost is very high and the funds are tight; I can't hire an artist. But I think this AI-generated one needs to be rendered.

<Solution to Reduce "Plastic Feel" in AI-Generated Art and Enhance Realism>

---

> 一. Optimize Generation Models and Parameters
1. Use Realistic Models and LoRA Adjustments
- Employ realistic-style base models (e.g., ”Majic Realistic v7”) trained for detailed skin and material rendering.
- Apply LoRAs optimized for texture (e.g., Skin Texture Adjustment LoRA) with weights set to ”0.7-0.8” to enhance skin pores and reduce overly smooth surfaces.

2. Adjust Sampling and Iteration Settings
- Increase iteration steps (35+) and use samplers like ”DPM++2M Karras” for stable detail generation.
- Fix facial distortions with plugins like ”ADetailer” to avoid artificial-looking textures.

3. Seed Control and ControlNet Integration
- Lock the seed value for consistency, then use ”ControlNet”with line art or reference images to maintain structural accuracy and reduce texture loss.

> 二. Refine Material and Lighting Details
1. Enhance Material Descriptions
- Specify materials in prompts (e.g., ”matte leather”, ”rough linen”, ”oxidized metal texture”) to guide AI toward realistic surfaces.
- Add light descriptions (e.g., ”warm pendant light casting soft shadows”) to simulate natural reflections.

2. Layer-Based Lighting Adjustments
- Render separate layers (base color, highlights, shadows) and composite them in tools like Photoshop for depth.
- Apply ambient occlusion (AO) to strengthen contact shadows and eliminate "floating" objects.

> 三. Post-Processing and Detail Enhancement
1. Add Manual Textures and Noise
- Apply noise filters or grain overlays in Photoshop to mimic real-world surface roughness.
- Use brushes to add scratches, stains, or imperfections for a less "perfect" look.

2. Sharpening and Color Correction
- Apply ”smart sharpening”to edges for clarity (avoid oversharpening).
- Adjust curves and saturation (e.g., reduce blue channel brightness) to naturalize shadows and tones.

---

> 四. Tool-Specific Workflows
1. Domain-Specific Tools
- Use tools like ”TMALL Jiazuo” for physics-optimized renders (e.g., fabric folds, metal reflections).
- Simulate traditional art styles (e.g., ”Artflow AI” for watercolor/oil brushstrokes) to mask synthetic textures.

2. AI Plugins for Targeted Fixes
- Combine ”ControlNet”line art constraints with ”inpainting” to fix errors (e.g., distorted hands).
- Use ”img2img” tools (e.g., ”Simpler AI”) to overlay reference textures for refinement.

---

> 五. Case Studies and Tips
- Case 1: Realistic Skin
Generate with Stable Diffusion + skin LoRA → refine facial lighting via ControlNet → add noise layers in Photoshop for natural pores.
- Case 2: Furniture Rendering
Use ”TMALL Jiazuo” with prompts like ”brick-patterned wallpaper ”→ manually adjust shadows/highlights for depth.

>Key Notes:
- Avoid over-relying on single parameters; combine tools for best results.
- Some tools (e.g., ”TMALL Jiazuo”) require payment for commercial use.

By implementing these strategies, AI-generated art can achieve lifelike textures and reduced "plastic" appearance.
