使用自适应灯光，渲染更快速

V-Ray 3.5 introduces Adaptive Lights, a fast new lighting algorithm that speeds up rendering in scenes with many lights.

With Adaptive Lights, V-Ray determines which light sources are most important, so ray tracing calculations are focused and more precise. When tested on multiple CPU and GPU scenes, render times were typically two to seven times faster.
