VRay RT demo videos

Here are some demo videos on VRay RT. VRay RT is an ActiveShade renderer that complements the VRay production renderer. Apparently, It uses CPUs on your network to provide the image. Mental Ray introduced the final gather preview which I found helpful when tweaking physical settings that can be counter-intutive at times. I found leaning Vray very challenging because of the "tweak and wait" pipeline. This should help artists new to VRay.
