This page provides information about the V-Ray Frame Buffer tab of the System Settings rollout. Parameters Image Effects Update Freq.  – Determines how quickly changes to VFB layers are reflected in the interactive render. This value is a percentage of the total render time.  Autoswitch to Effects Result  – When enabled, the render automatically switches to the Effects Result render channel. The Effects Result channel holds all render channels. Enable this option when the effects are necessary in post-edits. If only the colors need to be previewed, disable this option.  Image to Blender  – When enabled, the completed render (including render channels) is transferred to Blender. This allows rendering in V-Ray and compositing in Blender of the same render. The Extra Tex and Sampler Info channels currently do not transfer. Additionally, channels like Render ID, Material ID, and Object ID produce different visual results from the VFB. VFB Always On Top  – Forces the VFB window to stay on top during rendering.
