Kelsi	77012adbc6	Add alpha-tested foliage shadows: per-batch texture binding and shadow map receiving ... Shadow casting: foliage batches now bind their actual texture in the shadow pass with alpha testing, producing leaf-shaped shadows instead of solid cards. Uses a per-frame resettable descriptor pool for texture sets. Shadow receiving: foliage fragments now sample the shadow map with PCF instead of using a flat constant darkening.	2026-02-23 05:55:03 -08:00
Kelsi	ef1e5abe8e	Add shader-driven tree beautification: wind sway, SSS, color variation, AO ... - Vertex wind animation: 3-layer displacement (trunk/branch/leaf) with quadratic height scaling so bases stay grounded - Shadow pass: matching vertex displacement split into foliage/non-foliage passes, removed UV-wiggle approach - Leaf subsurface scattering: warm backlit glow when looking toward sun - Per-instance color variation: hue/brightness from position hash via flat varying to avoid interpolation flicker - Canopy ambient occlusion: height-based darkening of tree interiors - Detail normal perturbation: UV-only procedural normals to break flat cards - Bayer 4x4 ordered dither replacing sin-hash noise for alpha edges - Foliage skips shadow map sampling and specular to prevent flicker from swaying geometry sampling unstable shadow/highlight values	2026-02-23 03:53:50 -08:00
