Would be useful to have a few representative scenes (standalone web apps) with a shape in the middle that has customizable material, roughness etc., and be able to tweak the scene lighting; should provide a nice way to quickly find reasonable material/lighting values
Perhaps focus on materials first, with fixed lighting; there are more material options than light options, and having fixed lighting would simplify the UI significantly.
