SourceBridge v1.1.2

Fixed

• Blue tint in Lit mode caused by TOOLS textures blocking light (NODRAW, CLIP, TRIGGER, SKYBOX, etc.)
• TOOLS-only meshes now have shadow casting and distance field lighting disabled at the component level
• TOOLS materials switched to Unlit+Translucent base so they don't interact with the lighting system
• Lit mode normals using broken centroid heuristic replaced with VMF plane normals (import and reload paths)
• Base materials missing Roughness=1.0 and Metallic=0.0 causing specular blue sky reflections
• Missing tangent data on imported proc mesh sections causing flat shading in Lit mode
• Save/reload persistence for props (UStaticMesh) and worldspawn brushes (StoredBrushData + PostLoad reconstruction)
• Texture z-fighting caused by csgRebuild running after import
• Texture sizes not reloading correctly on re-import

Added

• Source Material Browser panel with texture preview thumbnails
• Persistent material and texture re-import on subsequent loads

SourceBridge v1.1.1

Added

Map Authoring Workflow (Phase 15)

• Per-face material editing for brush entities (select face, apply material from picker)
• Brush entity spawning with default geometry (creates box brush on spawn)
• Shape overrides for spawned brush entities (box, wedge, cylinder, arch)
• Static mesh to brush conversion on export (convex decomposition)
• Worldspawn brush creation and Tie to Entity tools
• Export validation for brush entities and degenerate geometry

Full Round-Trip Material Pipeline (Phase 16)

• Central material manifest (USourceMaterialManifest UDataAsset) tracking all Source materials
• Persistent texture import: VTF decoded to UTexture2D assets (survive editor restart)
• Persistent material import: UMaterialInstanceConstant assets with proper base materials
• Manifest-first material mapping on export (correct Source paths, no more broken name-based mapping)
• MaterialAnalyzer: extracts textures, blend mode, two-sided flag from arbitrary UE materials
• Custom UE material export: TGA → VTF conversion with DXT1/DXT5 format selection and mipmaps
• VMT generation from material analysis (maps UE properties to Source VMT parameters)
• Lossless re-export of imported materials using stored VMT params from manifest
• Custom material files automatically packed into BSP via bspzip

Fixed

• Compile pipeline failing on relative VMF paths (now converts to absolute)
• Spawn validation failing on imported maps

• Jump-to-node navigation (select entity → graph pans to its node)
• I/O connection parameter display and inline editing
• Entity-specific editor sprites (lights, spawns, props, triggers)
• PIE runtime with Source spawn points, first-person walking pawn, and noclip
• Tool texture per-face hiding in PIE mode
• SourceBridge GameMode for Play-In-Editor testing

Fixed

• VMF plane winding for correct front-face rendering on import
• UV computation for imported brush textures
• Material rendering using Material Instance Dynamic instead of per-material UMaterial
• VPK archives being wiped during BSP import cache clear
• VMT parser handling unquoted keys/values and nested quoted strings (water materials)
• Material search ordering (check VPK before recursive disk scan)
• Large map import performance (progress bars, reduced logging)
• MDL header offset bug causing model imports to fail
• Source → UE rotation conversion for props
• FGD parser stack overflow from circular inheritance
• I/O graph showing wrong classnames during import (deferred rebuild)
• I/O connections from BSPSource-decompiled VMFs using ESC (0x1b) separator

Changed

• Release workflow now downloads and bundles BSPSource v1.4.7 automatically

Fixed

• FGD parser infinite loop causing UE Editor to hang at 73% on startup (rewritten based on ValveFGD reference)
