Sunlight and directional lights
Adjust the shared sun or place a separate directional light and use its own Inspector.
There are two related lighting controls: the project’s shared scene sun, and a Directional Light object you can place from Lights. Sun settings change the environment lighting; the placed object has its own Inspector. Do not treat them as a single object with only one possible instance.
Adjust the shared sun
Open Settings, then Project → Canvas & drawing → 3D & Lighting. In Sun, adjust Azimuth, Elevation and Intensity, and use Enable Shadows for the scene sun’s shadow setting. Azimuth turns the heading; Elevation changes the sun height above the horizon.
Adjust the Presentation environment
In Presentation, the environment’s sun controls provide Time Presets, the Sky Dial and Light Warmth. These change the shared environment lighting. Set the project site under Site & location when you need the location-aware behavior.
Place an additional directional object
Open Lights → Core Fixtures → Directional Light and place it on the canvas. Select the object to edit its offered Location, Light Color and Brightness controls. Its brightness unit is Lux, not the lumens used by point fixtures.
Inspect the correct setting
Check whether the selected object or the shared environment is responsible for the change you need. Adjusting one should not be described as editing the other. Review the scene’s lighting and shadows in the view used for presentation.
