1. This is awesome! Thanks for sharing all of your knowledge!

  2. Thanks for these Redshift tutorials.

    Question: How do you decide which roughness parameters to plug your roughness into?
    In example 2, you chose to put the roughness into the diffuse_roughness and the reflection_roughness. I see people sometimes opt to use the refractive roughness as well. I’m never sure what’s appropriate.

    Any advice is appreciated, thanks!
