Hi Larry, With a spectral renderer, assuming storage every nanometers, 400+ irradiance channels are totally plausible. This is more a research case though, e.g. Mitsuba 2, but it is possible to see where this goes as soon as you start combining that with AOVs, e.g. spectral direct vs spectral indirect, per-light contribution, etc…
