Brisa Lite 2.9 — Existing Effects Refinement

Visual revision

• Fixed water reflections being weakened twice by transparency. Reflected clouds remain visible while the bottom still shows through.
• Improved rain-ring rim visibility with independent surface blending, retaining varied drop positions, sizes and lifetimes.
• Added finer cloud-shape detail, more defined edges and stronger body shading. The refined Balanced sky uses one extra cloud-noise sample; Detailed reuses its existing detail sample.
• Refined caustics into finer, less uniform ridges, retaining two texture samples and the existing light/depth restrictions.
• Strengthened grazing-angle glass reflections while preserving clear frontal views and pigment-dependent glass shadows.
• Retained balanced sunset colors, optional refinement controls and the Ultra Lite defaults.

Verified in 14 new Minecraft 1.21.11 / NeoForge / Iris scenes and all five quality profiles, with additional compiler/GPU checks across four representative Minecraft versions. Compared directly against the initial 2.9 with the same options. Performance measurements are isolated GPU timings, not gameplay FPS.
