Open the panel via Panels → Libraries → Sky Model Library.
The panel contains:
Model list — all available sky models, grouped into two families: Environment Shaders and Discrete Light Arrays.
Hemisphere preview — a fisheye (equidistant) projection of the sky radiance, updated in real time as parameters change.
Parameters — per-model sliders and controls for turbidity, solar position, irradiance components, and other model-specific inputs.
Documentation — brief description, parameter table, renderer compatibility, and literature reference for the selected model.
Code — a live XL/RGG snippet reflecting the current parameter values, plus hardcoded typical-scenario examples for quick copy-paste.
Insert button — copies the current code snippet to the system clipboard.
