- Introduced the two-times upscale specification detailing requirements for unified output, fixed model presets, arbitrary dimensions, and consistent job behavior. - Added scenarios for existing models, repeated upscale, and handling of alpha preservation. - Created the unified depth plane specification outlining geometry modes, stable interface, and asset evaluation. - Defined scenarios for mode switching, relief and camera preservation, and validation of delivered assets.

# image-result-materials Specification
|
||
|
||
## Purpose
|
||
TBD - created by archiving change refine-image-output-semantics. Update Purpose after archive.
|
||
## Requirements
|
||
### Requirement: Image color drives generated material IOR Level
|
||
系统 SHALL 将 Plane、Depth Plane 与 Cutout 的非 Shadeless 生成材质中 `O Image Layer` 的 Color 输出直接连接到 Principled BSDF 的 IOR Level，同时保留既有 IOR、Base Color、Roughness、Alpha、Normal 与 Displacement 连接。
|
||
|
||
#### Scenario: Dark image content suppresses highlights
|
||
- **WHEN** 生成材质采样到黑色或暗色图片内容
|
||
- **THEN** Principled BSDF 的 IOR Level SHALL 接收对应的低颜色值，从而降低该区域的高亮
|
||
|
||
#### Scenario: Bright image content preserves direct color response
|
||
- **WHEN** 生成材质采样到白色或亮色图片内容
|
||
- **THEN** Principled BSDF 的 IOR Level SHALL 接收 `O Image Layer` Color 的直接转换值，不经过额外缩放或固定上限
|
||
|
||
#### Scenario: Generated material keeps its IOR value
|
||
- **WHEN** Cutout 或 Depth Plane 以 IOR `1.2` 创建材质
|
||
- **THEN** 系统 SHALL 保留 IOR `1.2`，并由 Color 独立驱动 IOR Level
