-# Materials and Color
-
-NETFISHING uses simple colors and readable material separation rather than realistic texture detail.
-
-## Recommended material approach
-
-For initial assets, use simple material slots.
-
-Examples:
-
-- `mat_grass_light`
-- `mat_grass_dark`
-- `mat_moss`
-- `mat_soil`
-- `mat_sand`
-- `mat_wood_light`
-- `mat_wood_dark`
-- `mat_stone_light`
-- `mat_stone_dark`
-- `mat_teal`
-- `mat_coral`
-- `mat_cream`
-
-## Material limits
-
-Suggested limits:
-
-- Small props: 1–4 materials
-- Medium props: 2–5 materials
-- Large structures: 2–6 materials
-
-Avoid placing dozens of material slots on a single small object.
-
-## Color priorities
-
-Environment colors should generally be calmer than:
-
-- Characters
-- Items
-- Interaction points
-- Signs
-- Bobbers
-- Important landmarks
-
-Use darker structural colors for:
-
-- Timber gaps
-- Building supports
-- Outlines
-- Deep water accents
-- Visual separation
-
-Use brighter accents sparingly.
-
-## Textures
-
-Do not create textures unless:
-
-- The issue requests them
-- The asset clearly benefits from them
-- The texture workflow has been approved
-
-Avoid:
-
-- Large 4K texture sets
-- Unique texture files for every small prop
-- Baked lighting
-- Complex PBR workflows
-- Blender-only procedural shaders
-- Unnecessary normal maps
-- Unnecessary transparency
-
-If a texture is required, use practical sizes appropriate to the asset.
-
-## Blender materials
-
-Use materials that transfer cleanly through GLB.
-
-Keep Blender shader nodes simple.
-
-A basic Principled BSDF with:
-
-- Base Color
-- Roughness
-- Limited metallic use
-
-is normally sufficient.
-
-Do not rely on unsupported procedural nodes.
-
-## Compatibility renderer
-
-All materials must be tested using Godot’s Compatibility renderer.
-
-Confirm:
-
-- Colors appear correctly
-- Transparency behaves correctly
-- Shading remains readable
-- Materials do not require Forward+ features
-- No texture references are missing
