Antialiasing FilterAntialiasing Filter – Enables or disables anti-aliasing.
Size / Type – Controls the strength of the anti-aliasing filter and the type of anti-aliasing filter to use. See the Antialiasing Filter example below.

Some of the options are different when the Render Engine is set to GPU.
Adaptive Lights – Number of lights from the scene that are evaluated by V-Ray when the Adaptive the Adaptive Lights option is enabled. Lower values make the rendering go faster, but the result is potentially noisier. Higher values cause more lights to be computed at each hit point, thus producing less noise but increasing render times.
When enabled, V-Ray chooses at random the specified number of lights and evaluates only those for the rendering, thus speeding up render time. This option can introduce a visible degree of additional noise, but it makes it possible to render images that would otherwise take a very long time.
Max Trace Depth – Overrides globally the reflection and refraction depth (number of ray bounces/refractions). When this is disabled, the depth is controlled locally by the materials/maps. When enabled, all materials and maps use the depth specified here. If GPU is the render engine, it limits the reflection and refraction trace depth.
Opacity Depth – Controls to what depth transparent objects are traced.
Max Ray Intensity – Specifies the level to which all secondary rays are clamped.
Secondary Ray Bias – A small positive offset that is applied to all secondary rays; this can be used if you have overlapping faces in the scene to avoid the black splotches that may appear.
Adaptivity Clamp – Specifies an intensity limit for the adaptive bucket and progressive samplers to avoid excessive sampling of overexposed areas. Lower values mean a lower limit and potentially noisy overexposed areas. Higher values produce more samples in overexposed areas.
Firefly Removal – Removes firefly artifacts from the rendered image. The default value of 0.05 is ideal in most projects. Lower values are less aggressive at removing fireflies, while higher values are more effective but may start removing legitimate features of the image (i.e. small bright highlights). 0 disables the effect completely.

Firefly Removal is only available for Bucket Sampler and V-Ray CPU.
Embree – Enables the Intel Embree raycaster. This option is enabled by default. We suggest it not be disabled, as the Embree raycaster is ideal for almost all scenarios.
Conserve Memory – Embree uses a more compact method for storing triangles, which might be slightly slower but reduces memory usage.
