Set sunlight and live shadows
Where
3D settings then Scene lighting
Add controllable lighting or live shadows to the model display.
Steps
- Open 3D settings and decide whether to Enable scene lighting; baked textures may look better with it off.
- Enable shadows if you want live shadows, including over baked unlit textures.
- Adjust Sunlight pitch and Sunlight rotation to choose the direction.
- Adjust Sunlight intensity when scene lighting is enabled.
- Tune Shadow darkness, Shadow colour, Shadow quality and Shadow bias.
- Compare performance and appearance, then publish.
Expected result
Each background retains its own lighting and shadow settings.
Linked geometry and hidden/nonrenderable objects do not cast or receive dynamic shadows. Visible unlinked model surfaces retain the scene lighting controls. Shadows baked into textures cannot be removed.
Tips and limits
Live shadows add to shadows already baked into textures; they cannot remove baked shadows. Higher quality costs more rendering work. Too much bias can detach shadows from surfaces. Ambient-light controls were removed and are not part of the current settings panel.
Effect on the published viewer
Lighting and shadow changes remain draft until published.
