Fuchs & Vogel have been previewing an advanced copy of VRAYforC4D which makes use of the new V-Ray 3 Core. This presentation shows how you can reduce your render times when rendering hair, by using the new Embree acceleration setting.
[pullquote]how you can reduce your rendertimes when rendering hair[/pullquote]The Embree setting is based off of the Intel® Embree ray caster, which was developed to provide fast ray tracing kernels for their CPU’s, designed for Monte Carlo ray tracing.
V-Ray 3.0 takes advantage of the Intel® Embree ray caster, allowing you to enable the setting. This gives you faster performance with static and motion blurred geometry, proxy objects and instances within the V-Ray 3 core.
Simply by flicking the Embree switch in VRAYforC4D, you can really see a reduction in render times when rendering things like instances – hair, grass systems, etc.
