Combined Post-Process Implementation Guide

Implement Combined post-processing effects across three modules following the dependency chain: LumeRender → Lume3D → LumeScene

Task and Boundaries

This skill guides implementation of single-pass post-processing effects in OpenHarmony Graphics3D.

Applicable:

• Effects running in single fullscreen shader pass (tone mapping, color grading, vignette)
• Adding effects to Combined post-process system

Not Applicable:

• Effects requiring separate render passes (bloom with blur passes, depth-of-field, motion blur)
