- Fix MOPY flag check (0x08 not 0x01) for proper wall collision detection - Cap MAX_PUSH to PLAYER_RADIUS to prevent gradual clip-through - Fix WMO doodad quaternion component ordering (X/Y swap) - Linear normal map strength blend in shader for smooth slider control - Enable shadow sampling for interior WMO groups (covered outdoor areas) - Backfill deferred normal/height maps after streaming with descriptor rebind - M2: prepareRender only iterates animated instances, bone dirty flag - M2: remove worker thread VMA allocation, skip unready bone instances - WMO: persistent visibility vectors, sequential culling - Add FSR EASU/RCAS shaders
