Overview
The Common tab of the VRayRenderer provides access to image filtering and Antialiasing options that are the primary means of render quality and speed control for V-Ray. As well, Caustic light calculation, such as light bending through glass, can be enabled here.
The tab is broken up into three rollouts.
- Rendering – This rollout contains options to set the size of the rendered image and define the type of Aliasing used.
- Antialiasing – Parameters in this tab control V-Ray's render quality. This can have a large effect on fine-tuning render times.
- Caustics – This rollout contains controls for enabling and fine tuning how the renderer handles Caustic lighting effect calculations during rendering.

Rendering
Texture Filter Type – Used to select the filtering algorithm to use when remapping pixels from their original positions to new positions. This can help avoid problems with image quality, particularly in high contrast areas of the frame, where highly aliased or jagged edges may appear if pixels are not filtered and retain their original values.
Impulse – Remapped pixels carry their original values.
Cubic – Remapped pixels receive some smoothing.
Keys – Remapped pixels receive some smoothing, plus minor sharpening (as shown by the negative -y portions of the curve).
Simon – Remapped pixels receive some smoothing, plus medium sharpening (as shown by the negative -y portions of the curve).
Rifman – Remapped pixels receive some smoothing, plus significant sharpening (as shown by the negative -y portions of the curve).
Mitchell – Remapped pixels receive some smoothing, plus blurring to hide pixelation.
Parzen – Remapped pixels receive the greatest smoothing of all filters.
Notch – Remapped pixels receive flat smoothing (which tends to hide moire patterns).
Lanczos4, Lanczos6, and Sinc4 – Remapped pixels receive sharpening which can be useful for scaling down. Lanczos4 provides the least sharpening and Sinc4 the most.
Format – The format to which you want to output the image sequence. If the format does not yet exist, you can select new to create a new format from scratch. The default setting, root.format, resizes the image to the format indicated in the Project Settings.
Overscan – The maximum additional pixels to render beyond the left/right and top/bottom of the frame. Rendering pixels beyond the edges of the frame can be useful if subsequent nodes need to have access outside the frame. For example, a Blur node or LensDistortion node down the node tree may produce better results around the edges of the frame if overscan is used.
