To build a light source with the same angle of view (Hotspot) as the camera FOV

Submitted by Any on Mon, 2020-07-27 10:06

Good day!

Let's say that the scene has a camera - $Camera001 and a light source like Standard Target Spot - $Spot001.Light shape type - rectangle. $Spot001.aspect = renderWidth/renderHeight ($Camera001 aspect) How to calculate the parameter $Spot001.hotspot so that the angle of the cone of light is equal to the angle of the cone of the camera. Copy parameter $Camera001.curFOV, or even changing its type $Camera001.fovType does not give the desired result...???

What happen when you match the positions of the Camera and the Light and the positions of the Camera's target and the hotspot's target, and then you use this:

$HotspotLight.hotspot = $Camera.fov
