🆕 What's New in v1.0.4 — Profile Rebalance, Translucent Blocks & Glass Rendering

Version 1.0.4 delivers a full quality-profile rebalance for smoother progression, introduces proper translucent block rendering for ice and glass, adds a dedicated Iris/Oculus translucent terrain pass, and fixes a cross-vendor GLSL compatibility issue.

🔄 Full Profile Rebalance

All six quality profiles (VERY_LOW → EXTREME) have been rebalanced for a smoother, more logical feature progression:

Profile	Key Changes in v1.0.4
VERY_LOW	Sun intensity lowered to Dim (1), underwater night set to Moonlit Pool for visibility.
LOW	Ambient brightness lowered, cozy lights disabled, Filmic tone mapping (ACES), underwater night set to Dim. Stars upgraded to Standard.
MED	Godrays now enabled (Fast quality) — this was the biggest missing piece in the sweet-spot preset. PBR strength raised to Standard. Meteor frequency normalized.
HIGH	SSAO now enabled (Subtle) — contact shadows appear at this tier. Godrays bumped to Balanced. Moon intensity lowered to Standard.
ULTRA	Godrays raised to High. TAA strength at Balanced.
EXTREME	Water wave scale pushed to Stormy. Underwater night set to Pitch Dark for maximum survival realism. Photographic (AgX) tone mapping.

🧊 Split Ice & Glass Block Rendering

• Regular ice (minecraft:ice, block ID 10005) now renders with its actual texture and semi-transparency instead of being fully opaque. Transparency scales with the WATER_TRANSPARENCY setting (Clear / Balanced / Deep).
• Packed ice, blue ice, and frosted ice (block ID 10007) are now rendered opaque with texture — distinct from regular ice so the visual difference is clear.
• All glass blocks and panes (block ID 10008), including every stained-glass variant and tinted glass, now render with their actual texture and proper transparency. Glass opacity scales with WATER_TRANSPARENCY. This eliminates the old "invisible glass" problem where glass blocks disappeared against bright skies.
• Both ice types and glass are handled by the new gbuffers_terrain_translucent pass, ensuring correct rendering on Iris/Oculus split-translucent pipelines.

🪟 New Translucent Terrain Pass (gbuffers_terrain_translucent)

• A new gbuffers_terrain_translucent.fsh / .vsh shader pair was added. This pass handles water, ice, glass, and nether-portal blocks in a single Iris/Oculus-compatible translucent terrain path.
• Mirrors the existing gbuffers_water.fsh logic so translucent blocks render identically regardless of whether the loader uses a unified or split translucent G-buffer path.
• Nether portal plasma, ice Fresnel, glass opacity, and water Fresnel/ripples all route through this pass.

🛠️ GLSL Compatibility Fix

• Replaced all fma() calls with direct multiply-add expressions across every shader file. The fma() intrinsic, while correct on most modern GPUs, caused compilation failures on certain drivers (particularly older Intel iGPUs and some Mesa versions). The replacement a * b + c expressions are mathematically equivalent and compile universally.
