Interactive - Toggles between interactive and production rendering. Features such as Light cache and on-demand mipmapping are not supported in interactive mode.
Lock Render Camera/View – When on, locks the render camera from Render from Camera/View .
Render from Camera/View – Specifies the view that renders when you click the V-Ray render button.
Lock Image Aspect – When enabled locks relation between X value and scales the Y of according to the imageviewport size.
Resolution – Sets the resolution output for rendering.
Export VRScene – Enables the export of a .vrscene file when you click the V-Ray render button. The .vrscene file is saved in Installed_Directory_Unreal\UE_4.XX\Engine\Plugins\VRayForUnreal\Content.
Compress – Compresses geometric information so that the resulting .vrscene file is smaller.

Render Settings
Time Limit(Minutes) – Specifies the maximum time (in minutes) for refining the image.
Noise Limit – A threshold that determines when to stop refining a pixel. Higher values allow more noise in the image, while lower values try to reduce the noise. A value of 0.0 traces the entire image unconditionally.
Sample Limit – Specifies the maximum samples per pixel for refining the image. V-Ray performs adaptive sampling on the image, trying to put more samples into areas that have more noise.
Global Illumination
GI Engine – Specifies the type of secondary engine. Note that Brute force is always used as a primary engine.
Brute Force
GI Depth – The number of bounces for indirect illumination.
Light Cache
Subdivs – Determines how many paths are traced from the camera. The actual number of paths is the square of the subdivs.
Sample Size – Controls the size of the individual light cache samples.
Retrace – Enables retracing of GI near corners. This helps prevent light leaks and flickering. The value specifies the extent to which GI near corners are retraced instead of being read from the light cache. A value of 0.0 disables retracing. A value of 2.0 is good for still images. Higher values will result in more rays traces at render time.
Render Elements
Denoiser – A render element that progressively applies a denoising operation to the image. The denoising operation detects areas where noise is present and smooths them out.
Environment – Specifies which VRaySettingsEnvironment blueprint will be used at render time for environment overrides.
