# Gear fit report: `docs/screens/realism/2026-11-01-gear`

Influencer (`npc_coat`) portrait, forced with `--portrait-type=2`, before the gear-fit
changes (`da876e3`, with the capture yaw/focus fixes backported) and after them (`a478bfb`).
Both frames use the same camera, sun and portrait staging. The focus disc is hidden because
it is a gameplay overlay, not part of the character still.

| measurement | before | after |
| --- | --- | --- |
| sunglasses width | 0.282 m (0.90× head) | **0.202 m** (0.64× head) |
| bag body inner face | 0.168 m (coat skirt 0.225, dress 0.260) | **0.262 m** (clears both) |
| firefighter helmet brim | sat on the brow ridge | **raised 2 cm** |

Capture commands:

```

The judge improved the portrait from **overall 2 / characters 1** (baseline) to
**overall 3 / characters 2** (candidate); the remaining fixes are the broader realism
targets (skin/cloth shaders, GI, backdrop haze), not gear fit.

Vision judge: `google/gemini-2.5-flash-lite` (scores 0-10, higher is more realistic compared with the concept target).

**baseline / npc_portrait** fixes:
- Improve character model realism with more detailed facial features, realistic skin shaders, and better clothing textures.
- Enhance material properties for all objects, especially the brick building and pavement, to better simulate real-world reflectivity, roughness, and subsurface scattering.
- Increase texture resolution and detail for all assets, particularly for the brickwork, pavement, and character clothing, to reduce the appearance of tiling and blurriness.
- Refine lighting to match the warm, directional sunlight and soft shadows of the target image, paying attention to ambient occlusion and global illumination.
- Add atmospheric perspective and volumetric fog to the backdrop to create a sense of depth and distance, mimicking the haze seen in the target image.

**candidate / npc_portrait** fixes:
- Improve character model realism with more detailed facial features, realistic skin shaders, and better hair simulation.
- Enhance material properties for clothing, pavement, and buildings to include subsurface scattering, anisotropic reflections, and more varied roughness maps.
- Increase texture resolution and add micro-detail (e.g., pores, fabric weave, concrete imperfections) to all surfaces.
- Implement more sophisticated global illumination and atmospheric scattering for a softer, more realistic lighting and haze effect.
- Refine the backdrop by adding more complex building geometry, varied foliage, and realistic distant city details with appropriate atmospheric perspective.
