Spotlight Hotspot

Adjusts the angle of a spotlight's hotspot.

Reference

This button replaces the Zoom All button when a spotlight viewport is active.

Click this button, then move the mouse in the spotlight viewport to make the cone of the hotspot narrower or wider (the hotspot cone is shown in blue, the falloff cone is in gray).

Hold down the CTRL key while moving the mouse to lock the initial angle separation of the hotspot and falloff cones.

You can’t adjust the hotspot larger than the falloff, because that would change the falloff value. Likewise, when you reduce the falloff, it stops at the hotspot size (in both cases, separated by the Angle Separation, specified in the Preferences/Rendering page).

To override the separation of the hotspot and falloff parameters and cause the parameters to affect each other, hold down the SHIFT key.

How To

To change a spotlight's hotspot

1. Activate a Spotlight viewport.
2. Click Spotlight Hotspot.
3. Drag in the Spotlight view to change the hotspot angle:
• Dragging down widens (increases) the hotspot angle and illuminates more of the scene.

The hotspot grows inside the falloff as its angle increases. If you increase the hotspot angle far enough, the falloff angle also increases to stay 2.0 degrees greater than the hotspot angle.

• Dragging up narrows (decreases) the hotspot angle and illuminates less of the scene.

The hotspot shrinks inside the falloff as its angle decreases.
