Reflection Diffuse only show white

sample repo: https://github.com/ckse93/VideoDiffusionIssueSHowcase

Repo has detailed step by step workflow. as well as screenshot, python script compute result, and parameters

after running computeDiffuseReflectionUVs.py and mapping textures and reflection diffuse to objects, I noticed that reflection diffuse does not produce any color.

expected result is shown below, diffused light has color

solved. swizzle's channel is by default, set to rrr, changing it to rgb fixed it
