Architecture¶
How the _Core library is built. For advanced users who want to read the graphs or build their own master. See also: Naming and standards, Editing the masters.
How a master works¶
- Every surface comes from MF_KurinMaster (textures, color, normal, roughness, height). Layered masters call it once per layer.
- Add-ons are separate MF_Kurin... functions, chained one after another on Material Attributes. Each sits behind its own Use ...? switch.
- Each master has one output point: Break → Make Material Attributes → Output. Features never write into the output directly.
- Surface add-ons (Cover, Dust, Weather, Landscape Blend, Fuzzy Shading) also output their mask (0..1), so a custom master or a future Substrate setup can reuse them.

| MF_KurinWeather | Wetness, puddles, rain, streaks, shore, submerged, ice, frost, condensation | Wetness / Puddle / Frost / Submerged / Condensation Mask |
| MF_KurinCover | Moss, snow, leaves on top | Cover Mask |
| MF_KurinDust | Dust on up-facing surfaces | Dust Mask |
| MF_KurinRVTBlend | Landscape Blend from the Runtime Virtual Textures | Landscape Blend Mask |
| MF_KurinFuzzy | Fuzzy Shading | Fuzzy Mask |
| MF_KurinEmissive | Glow by a Mask Map channel | |
| MF_KurinOpacityMask | Cut-out, invert, contrast, camera fade | |
| MF_KurinFoliage, MF_KurinSubsurface | Foliage color variation, bush normals; light through leaves | |
| MF_KurinVegetationWind, MF_KurinClothWind | Foliage wind; waving cloth (WPO) | |
