LightPoint

The LightPoint class represents a point light source such bulb, candle, or torch. It includes a radius parameter to attenuate light intensity based on the distance between the light and the receiver. The area radius simulates a spherical light source, producing accurate soft shadows. An optional cubemap intensity texture can be applied to simulate direction-dependent color modulation.

info

In shadow-map mode, this light renders up to six shadow viewports.
