Feb 1, 2026February 2026: Focused rendering subsystem improvement in galacean/engine. Implemented a RenderTarget RenderBuffer Creation Refactor by introducing a private _createRenderBuffer method in GLRenderTarget to consolidate renderbuffer creation. This reduces duplication, simplifies maintenance, and aligns with the team’s code quality and stability goals. Commit 508ca7356e50fca92e1aaa0f691a3876d5dcb998 documents the change and ties to PR #2897. Overall impact: cleaner render path, safer future changes to renderbuffer handling, and improved maintainability of the rendering codebase.
