Apr 1, 2025April 2025: Key rendering improvements and validation tooling for Facepunch/sbox-scenestaging. SSR enhancements (roughness-based culling, reconstruction fixes, and shader/temporal reprojection optimizations) improved quality and efficiency. Replaced hardcoded light attenuation with defaults across CapsuleLight, LineRendererLight, and RectLight to simplify configuration. Added a depth-aware FBCopy mask test scene to validate multi-object and lighting scenarios. Business value: higher visual fidelity with less tuning, safer iterations, and stronger QA coverage.

Mar 1, 2025March 2025 performance snapshot for Facepunch/sbox-scenestaging focused on elevating visual fidelity, lighting realism, and editor workflow, while improving code maintainability. Key features delivered include Bloom post-processing improvements (smoother threshold curve, gamma control, biquadratic smoothing) with integration across the staging shader and removal of the Bloom2 component to simplify the render path. Area lights and scene lighting were enhanced with a new RectLight component, procedural gradients for area light cookies, and additional light types to improve realism and editor workflows. Lighting components were updated with Capsule Light gizmos, LineRendererLight subcomponent, and refined light size and attenuation logic across types. A GPU distance field rendering PoC was implemented to explore distance-field rendering on skinned models, with gizmo-based debugging for validation. Finally, test assets were expanded with a multi-resolution cubemap test scene and improved transparency/sorting test scenes to support rendering tests and visual verification.
