Biome Worlds

Climate drives palette, fog, vegetation density, and material wear.

Recipe

Climate drives the palette: pick one biome and key the light, world colour and material roughness to it (desert: warm sun, roughness 0.9, sand [0.75, 0.55, 0.3]; arctic: cool overcast, roughness 0.4 ice; jungle: saturated greens, low sun, high density; underground/underwater: near-black world, one practical light).

1. Light with lighting/light_rig.py: golden_hour (desert), overcast (arctic, jungle canopy), moonlight (underwater/cave, then keep exposure low), neon_night for bioluminescent caves.
2. Ground/material the hero with materials/pbr_material.py (sand, snow roughness 0.5, wet rock roughness 0.2 and coat_weight 0.3, moss green).
3. Fill the biome with set-dressing/scatter_props.py for rocks/crates/camps, and for vegetation or rocks on a terrain use geometry-nodes/scatter_points.py (surface, collection, density 2-8 per m2, align_to_normal False for trees).
4. Frame with camera-cinematography/camera_rig.py (lens_mm 35 for vistas, dof_fstop 4 for jungle depth).
5. Atmosphere: compositing/comp_grade.py stylized_bloom (jungle, underwater) or cinematic (desert, arctic); fog is world/volume based, set it in prose via a Volume Scatter on the world.
