- Shadow mapping via rlgl: custom depth FBO (2048x2048, 24-bit depth texture) instead of color-attachment approach. Proper depth-only render pass. - Shadow map bound via MaterialMapIndex.Emission (texture unit 1), sampled in shadow receiver shader with PCF 3x3 soft shadows. - Fixed inverted normals: Cross(ac, ab) for CW winding in OBJ files. - Linear workflow: pow(albedo, 2.2) before lighting, pow(result, 1/2.2) after. - Per-channel Fresnel: vec3 F0 + (1-F0)*pow(1-HdotV,5) instead of F0.x. - Single CollectLights call after BeginMode3D. - Shadow pass after BeginDrawing (inside frame). - Backface culling disabled globally for mixed-winding meshes. - Point light support: Light.Point/Directional factory methods, attenuation, ImGui inspector with type combo, position/range for point lights. - Floor rendered for both light types (shadow receiver or main shader). - 66/66 tests passing.
