Kelsi	30fa9836d9	Fix glow sprite flashing, move fadeAlpha to push constants, throttle character bones ... - Glow sprites now use dedicated vertex buffer (glowVB_) separate from M2 particle buffer to prevent data race when renderM2Particles() overwrites glow data mid-flight - Move fadeAlpha from shared material UBO to per-draw push constants, eliminating cross-instance alpha race on non-double-buffered UBOs - Smooth adaptive render distance transitions to prevent pop-in/out at instance count thresholds (1000/2000) - Distance-tiered character bone throttling: near (<30u) every frame, mid (30-60u) every 3rd, far (60-120u) every 6th frame - Skip weapon instance animation updates (transforms set by parent bones)	2026-03-04 08:17:32 -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
