Texturing and shading (Blender 5.2)

纹理制作与材质着色（Blender 5.2）

Expert shading is layered masks feeding physically plausible values: a clean base (scanned set or flat colors), then contrasty black/white masks that place color, roughness, height and subsurface, all editable in nodes. Values are judged under honest light in both engines, and baking comes last, for portability. If a sibling skill named here is missing from your available skills, ask the user to install it (

npx skills add scenario-labs/skills --skill <name>

); unattended, proceed from tool schemas and flag the gap.

REQUIRED BACKGROUND: scenario-blender-expert (execution channel, review loop, 5.2 API changes). Baking maps: scenario-blender-uv-baking. Lighting and final renders: scenario-blender-lighting-rendering.

Toolkit:

scripts/bx_materials.py

(builders, headless painting, checks; exercised by

tests/code/blender-texturing-shading/

sys.path.append("<this skill>/scripts"); import bx_materials as M

专业的材质着色是通过分层蒙版输入符合物理规律的数值：干净的基础层（扫描纹理集或纯色），然后是高对比度的黑白蒙版，用于控制颜色、粗糙度、高度和次表面散射，所有参数都可在节点中编辑。参数需要在两个渲染引擎的真实光照下校验，烘焙放在最后一步以保证可移植性。如果你可用的技能中缺少这里提到的关联技能，请让用户安装（

npx skills add scenario-labs/skills --skill <name>

）；无人值守时，按照工具架构继续执行并标记缺失项。

必备基础技能： scenario-blender-expert（执行通道、审核循环、5.2 API变更）。烘焙贴图：scenario-blender-uv-baking。光照与最终渲染：scenario-blender-lighting-rendering。

工具集：

scripts/bx_materials.py

（构建器、无头绘制、检查项；测试用例见

tests/code/blender-texturing-shading/

）。使用方式：

sys.path.append("<this skill>/scripts"); import bx_materials as M

。

Stance (the expert delta)

核心原则（专家级差异点）

Data maps are Non-Color, "not what looks better, what's correct" (Price). Only base color and emission are sRGB.
Normal map OR displacement, never both (Price, confirmed by Cycles lead Brecht): they encode the same relief. Displacement when heights will be combined or truly displaced; normal map for export and 8-bit safety.
Masks, not painted color. Kaspar and Price build every effect as a grayscale mask into a Mix or HSV Factor; color lives in the A/B inputs. Masks need contrast (Color Ramp stops pulled in) or they barely show. The same masks drive roughness, height and SSS.
Realism: scanned set plus masks; stylized: procedural (Price vs Kaspar and Ryan King). Kaspar strips photos to their pattern (blur plus grain extract) and adds grunge himself, and bakes at the end for portability (export, EEVEE load time), not for Cycles speed.
Micro detail in roughness, not bump, for skin and hair (Kaspar); edit roughness through HSV Value, never by unplugging the map (Price). Specular stays 0.5. Bump Distance is the real height of the map's 0..1: lower Distance, not Strength (Kaspar).
Judge honestly: Standard view, neutral mid-gray background, Base Color black to read roughness, a hard backlight and a light from below (Kaspar); grazing light for relief (Price); unlit for hand-painted albedo (Abbitt). EEVEE for iteration, Cycles as the truth, and they must match (Kaspar).
SSS follows anatomy (Kaspar): high on ears, nose, lids, lips, fingertips; low over bone. Black/white mask, Map Range sets values.
Bevel, AO, Pointiness and Random Per Island are Cycles-only, and Bevel/AO are stochastic [added, measured]: EEVEE shows no Bevel edges; thresholded live masks give 17 to 18% fractional metallic at any sample count. Bake before thresholding, or use vertex curvature.

数据贴图使用Non-Color色彩空间，「不是好看就行，而是要正确」（Price）。仅基础色和自发光使用sRGB空间。
法线贴图和位移二选一，绝不同时使用（Price，经Cycles负责人Brecht确认）：二者编码的是同一凹凸信息。需要组合高度效果或真实位移时用位移；需要导出或保证8位贴图兼容性时用法线贴图。
用蒙版而非直接绘制颜色。 Kaspar和Price将所有效果都制作成灰度蒙版，接入Mix或HSV节点的系数输入；颜色放在A/B输入槽中。蒙版需要有对比度（收紧Color Ramp的色标），否则效果几乎不可见。同一套蒙版可同时控制粗糙度、高度和SSS。
写实风格：扫描纹理集+蒙版；风格化：程序化（Price 对比 Kaspar与Ryan King）。Kaspar将照片提取为图案（模糊+颗粒提取），自行添加脏污效果，最后才烘焙以保证可移植性（导出、EEVEE加载速度），而非为了提升Cycles渲染速度。
皮肤和毛发的微观细节做在粗糙度里，而非凹凸贴图（Kaspar）；通过HSV的明度通道调整粗糙度，绝不要直接断开贴图连接（Price）。高光值保持0.5。Bump Distance 对应贴图0到1范围的真实高度：要降低距离值，而非强度值（Kaspar）。
真实校验： 使用标准视图、中性中灰背景，将基础色设为黑色以观察粗糙度，搭配硬边背光和底部补光（Kaspar）；用掠射光观察凹凸效果（Price）；无光照模式下检查手绘反照率（Abbitt）。迭代用EEVEE，最终效果以Cycles为准，二者必须匹配（Kaspar）。
SSS遵循解剖学规律（Kaspar）：耳朵、鼻子、眼睑、嘴唇、指尖处数值高；骨骼处数值低。用黑白蒙版控制，通过Map Range节点设置数值。
Bevel、AO、Pointiness和Random Per Island仅支持Cycles，且Bevel/AO是随机计算的 [新增，已实测]：EEVEE中不会显示Bevel边缘；无论采样数多少，实时蒙版阈值处理后会产生17%-18%的部分金属度。在阈值处理前先烘焙，或使用顶点曲率。

Workflow

工作流程

Base per part. Prefixed materials, placeholders removed,
```
diffuse_color
```
set; values picked on the Diffuse Color pass (matcap made Kaspar's skin too pale). Apply scale. GATE:
```
M.value_report(objs)
```
clean.
Base material. Set:
```
M.pbr_from_textures(mat, M.find_texture_set(dir), uv_map=...)
```
: color spaces by role, AO multiplied at factor 1 (Price: restores the cavity shadow flash capture removes;
```
ao_mode="gltf"
```
for games), bump only without a normal map,
```
height_as="displacement"
```
drops the normal map and sets Cubic interpolation, Displacement and Bump, Scale 0.2 for Poliigon (fixed 20 cm range); add Simple subdivision and shade smooth. UV tile = the set's physical size. Rigid, no UVs:
```
projection="BOX"
```
. Procedural: Object coordinates (UV on deforming meshes), Noise Detail at most 5 (cost doubles per level, Price). GATE:
```
M.audit_material(mat, obj)
```
has no errors.
Masks. Kaspar's rule is mask frequency against vertex density: vertex colors for broad soft masks (and Price's environments: tiling UVs repeat image strokes, layouts change), images for fine or exported detail, UV bands for hems. Headless:
```
M.mask_from_points
```
,
```
M.write_vertex_values
```
,
```
M.smooth_attribute
```
,
```
M.curvature_attribute
```
,
```
M.TexelMap
```
+
```
M.project
```
. Price's Color Burn: soft mask (A) burned by a contrast-ramped height map (B) breaks the mask along bricks or into grout (procedures P18). GATE: render each mask as emission.
Layers.
```
M.add_wear(mat, edge_color=..., edge_roughness=..., edge_metallic=1)
```
adds variation, cavity/grunge dirt and chipped edges. Blend modes: Multiply darkens (grime, mold), Screen lightens (efflorescence, highlights; Add exceeds 1), Subtract on the height chain for spalling (Price). Chain order sets age (a decal before grime reads old). Decals: Alpha into Factor, Extension Clip (
```
M.add_decal
```
). GATE:
```
M.preview(objs, out, rigs=("studio", "roughness"))
```
: effects follow form and water paths, nothing uniform, repeats broken.
Character specifics.
```
M.stylized_skin(mat, obj=body)
```
(masks
```
col_brighter/col_darker/col_lips/col_sss/col_rough
```
);
```
M.stylized_eye
```
per eye object (origin at the eyeball center) plus
```
M.cornea_material
```
and
```
cornea.visible_shadow = False
```
; hair shine: Anisotropic with a Tangent on a strand-aligned UV map (Cycles only). GATE:
```
rigs=("backlit",)
```
: red glow on ears, nostrils, lips, fingers; front not waxy; sclera off-white.
Stylized hand-painted light (Abbitt): lighter top, darker bottom, Multiply in crevices, Screen on extremities. Headless:
```
M.painted_light(mat, obj)
```
from a curvature attribute, bake Emit, judge with
```
rigs=("unlit",)
```
.
Painting, where masks cannot place it. GUI: brushes are assets (
```
Paint Hard/Soft
```
,
```
Airbrush
```
,
```
Blur
```
,
```
Smear
```
,
```
Fill
```
,
```
Mask
```
); a factory 5.2 session paints BLACK until the brush and unified color are set; strokes project from the screen, so face the surface (Abbitt); Erase needs an alpha channel; bleed 8 to 12 px (Kaspar, Abbitt). Use
```
M.gui_texture_stroke()
```
: it forces a redraw (projection painting occludes with the depth buffer of the previous draw: a stroke issued in the setup call painted 162 texels in one run instead of about 14,000, full coverage in another) and resamples dabs. Headless:
```
M.TexelMap
```
+
```
M.paint_stroke
```
paints by world distance, seams included;
```
M.dilate
```
, then
```
M.save_image
```
(images are never saved with the .blend by a script). GATE: renders from views crossing seams.
Lookdev check and bake.
```
M.preview
```
(EEVEE and Cycles, studio, backlit, roughness),
```
M.value_report
```
, labeled frames and node groups (Kaspar, Price). Bake procedural channels via Emission, 30+ samples, validate by rebuilding from the maps (scenario-blender-uv-baking).

各部件基础材质。 材质添加前缀，移除占位符，设置
```
diffuse_color
```
；在漫反射颜色通道中选色（matcap会让Kaspar的皮肤看起来过白）。应用缩放。检查点：
```
M.value_report(objs)
```
无异常。
基础材质。 调用
```
M.pbr_from_textures(mat, M.find_texture_set(dir), uv_map=...)
```
设置：按用途设置色彩空间，AO以系数1相乘叠加（Price：这能还原闪光灯拍摄时丢失的缝隙阴影；游戏场景用
```
ao_mode="gltf"
```
），仅bump时不使用法线贴图，
```
height_as="displacement"
```
会弃用法线贴图并设置三次方插值、Displacement and Bump模式，Poliigon纹理的缩放设为0.2（固定20厘米范围）；添加简单细分并平滑着色。UV平铺尺寸=纹理集的物理尺寸。刚体无UV：
```
projection="BOX"
```
。程序化材质：使用物体坐标（变形网格用UV），Noise Detail最高为5（每提升一级性能开销翻倍，Price）。检查点：
```
M.audit_material(mat, obj)
```
无错误。
蒙版制作。 Kaspar的原则是蒙版精细度匹配顶点密度：大范围柔和蒙版用顶点色（Price的环境场景同理：平铺UV会重复图像笔触，布局会变化），精细或需导出的细节用贴图，边缘饰边用UV条带。无头模式下：使用
```
M.mask_from_points
```
、
```
M.write_vertex_values
```
、
```
M.smooth_attribute
```
、
```
M.curvature_attribute
```
、
```
M.TexelMap
```
+
```
M.project
```
。Price的Color Burn技巧：用经对比度提升的高度图（B）叠加柔光蒙版（A）的颜色减淡效果，可让蒙版沿砖块或灰缝分布（见流程P18）。检查点：将每个蒙版作为自发光渲染验证。
层级效果。 调用
```
M.add_wear(mat, edge_color=..., edge_roughness=..., edge_metallic=1)
```
添加变化、缝隙/脏污和边缘剥落效果。混合模式：Multiply用于变暗（尘垢、霉菌），Screen用于变亮（风化白霜、高光；Add会超出1范围），高度链上用Subtract制作剥落效果（Price）。层级顺序决定老化程度（贴花放在脏污层之前会显得更旧）。贴花：Alpha通道接入系数，扩展模式设为Clip（
```
M.add_decal
```
）。检查点：
```
M.preview(objs, out, rigs=("studio", "roughness"))
```
：效果贴合形体和水流路径，无均匀感，平铺重复被打破。
角色专属效果。 调用
```
M.stylized_skin(mat, obj=body)
```
（蒙版包括
```
col_brighter/col_darker/col_lips/col_sss/col_rough
```
）；每个眼睛对象调用
```
M.stylized_eye
```
（原点在眼球中心），搭配
```
M.cornea_material
```
并设置
```
cornea.visible_shadow = False
```
；头发高光：使用Anisotropic，在发丝对齐的UV贴图上搭配Tangent节点（仅Cycles支持）。检查点：
```
rigs=("backlit",)
```
预览：耳朵、鼻孔、嘴唇、手指处有红色透光；正面无蜡质感；巩膜呈米白色。
风格化手绘光影（Abbitt）：顶部提亮，底部压暗，缝隙处用Multiply加深，边缘处用Screen提亮。无头模式下：通过曲率属性调用
```
M.painted_light(mat, obj)
```
，烘焙自发光，用
```
rigs=("unlit",)
```
校验。
绘制（蒙版无法实现的效果）。 GUI模式：笔刷为资产（
```
Paint Hard/Soft
```
、
```
Airbrush
```
、
```
Blur
```
、
```
Smear
```
、
```
Fill
```
、
```
Mask
```
）；Blender 5.2默认初始会话绘制颜色为黑色，需先设置笔刷和统一颜色；笔触从屏幕投影，因此要正对表面（Abbitt）；擦除需要Alpha通道；bleed范围8-12像素（Kaspar、Abbitt）。使用
```
M.gui_texture_stroke()
```
：它会强制重绘（投影绘制会使用上一次绘制的深度缓冲进行遮挡：在设置调用中发出的笔触一次仅绘制162个纹素，而非约14000个，另一次则完全覆盖）并重新采样笔触。无头模式下：
```
M.TexelMap
```
+
```
M.paint_stroke
```
按世界距离绘制，包含接缝；调用
```
M.dilate
```
后执行
```
M.save_image
```
（脚本永远不会将图像与.blend文件一起保存）。检查点：从跨越接缝的视角渲染验证。
外观开发检查与烘焙。 调用
```
M.preview
```
（EEVEE和Cycles，studio、backlit、roughness预设）、
```
M.value_report
```
，使用带标签的帧和节点组（Kaspar、Price）。通过自发光烘焙程序化通道，采样数30+，通过重建贴图验证效果（参考scenario-blender-uv-baking技能）。

Quality gates

质量检查标准

Measurable:

```
M.audit_material(mat, obj)
```
: color spaces by role, no image straight into Normal, explicit UV maps, Bump Distance at most 0.05, no Add Shader or raw summed normals, Emission Strength set, no gray constant metallic, normal map plus displacement flagged, non-Cubic displacement image, Noise Detail above 6, unsaved images.
```
M.value_report(objs)
```
: dielectric albedo within 30 to 243 sRGB (under 2% outside), metal above 180, fractional metallic under 5% (live Bevel/AO wear exceeds it until baked), roughness std above 0.01.
Scale applied; color attributes named
```
col_*
```
and matching every Attribute node exactly (Kaspar, Price).

Visual:

M.preview

EEVEE vs Cycles nearly identical; roughness row shows breakup; backlit glow only where flesh is thin; grazing light shows relief without terracing; repeats broken at distance; per-layer mute renders each add something (Price); scale against a human reference.

可量化指标：

```
M.audit_material(mat, obj)
```
检查项：按用途设置色彩空间、无图像直接接入Normal输入、明确指定UV贴图、Bump Distance不超过0.05、无Add Shader或原始法线叠加、Emission Strength已设置、无灰色常量金属度、标记法线贴图与位移同时使用的情况、位移图像未使用三次方插值、Noise Detail高于6、图像未保存。
```
M.value_report(objs)
```
检查项：电介质反照率在sRGB 30-243范围内（超出比例低于2%）、金属反照率高于180、部分金属度低于5%（实时Bevel/AO磨损在烘焙前会超出该值）、粗糙度标准差高于0.01。
已应用缩放；颜色属性命名为
```
col_*
```
格式，且与所有Attribute节点完全匹配（Kaspar、Price）。

视觉检查：

M.preview

中EEVEE与Cycles效果几乎一致；粗糙度预览行显示细节变化；背光仅在皮肤薄的位置有透光；掠射光下凹凸效果无阶梯感；远距离下平铺重复被打破；逐层静音渲染验证每层都有贡献（Price）；对照人体参考物确认比例正确。
