March 2026 (2026-03) — Bevy Engine: delivered a focused rendering correctness fix for unlit materials and improved overall visual fidelity and reliability. The patch ensures AlphaMode::Mask threshold is applied to unlit materials, aligning behavior with lit materials and eliminating the previous default fallback. This reduces visual discrepancies in transparency and enhances the quality of unlit surfaces in real-world projects. Key impact: - Corrects rendering of unlit materials with AlphaMode::Mask, improving visual fidelity and consistency across lighting states. - Strengthens shader correctness by ensuring alpha_cutoff is read for both lit and unlit materials. - Provides a concrete, test-verified improvement demonstrated in the transparency_3d example. Code reference: - Commit: 10243aaab5fbfe878b8a04a021b0a7ea15bc5794 - Change description: Moved the alpha_cutoff read out of the lit-only block; validates with unlit sphere example. - Co-authored-by: François Mockers. Business value: - Improves rendering accuracy and user-perceived quality for unlit materials, reducing confusion for artists and developers relying on Mask transparency in Bevy-based projects. - Enhances maintainability by consolidating material alpha handling in a shared path across material states.
