Can you please include the D5’s UI while you’re recording so I can check the settings that are observed in your file?

I can replicate this, but only when using thinner cloud presets.

Cloud type matters; some presets (e.g., Altocumulus, Cirrus) are naturally thinner and allow more light diffusion than Cumulonimbus or Stratus.

Even with high cloud amounts, D5’s physical sky model may still allow diffuse skylight (not direct sun rays).

Hi @Clov,

Please observe glass reflection where is visible sun shadow and GI under balcony while changing Sun orientation. The same in beta.
