Sampler Type – Specifies the image sampler type. Specific parameters for the selected type appear at the bottom of this rollout.

Progressive – Progressively samples the entire image. See the Progressive Sampler for additional parameters.
Bucket – Takes a variable number of samples per pixel depending on the difference in the intensity of the pixels. See the Bucket Sampler section for additional parameters. 

Render Mask Mode – Enables the render mask feature. The render mask allows you to define which pixels of the image are calculated. The rest of the pixels are left intact. This feature works best with the Bucket image sampler. The following types are available:

Disabled – The render mask is not used.
Texture – A texture map is used for the render mask. Black values in the map define pixels which are not rendered. Pixels with any other values are rendered. 
Objects – Renders only objects specified in a list.
Object IDs – Renders only objects with specified Object IDs.
Active Selection – Renders only the selected object or objects. 

Render Mask Texture – Specifies a texture map according to which V-Ray creates a render mask. This option is available when Render Mask Mode is set to Texture.

Render Mask Objects – A list that specifies which objects to be rendered. Objects part of a hierarchy can also be included. The object's children can be excluded by disabling the hierarchy icon (). This option is available when Render Mask Mode is set to Objects.

Render Mask Object Ids – A list that specifies which objects to be rendered based on their object ID. You can use ranges (e.g. 1-5) and separate the numbers with commas (e.g. 1,2,3). This option is available when Render Mask Mode is set to Object IDs.

Render Mask Clear – This option disables the currently selected render mask and clears the render buffer.

Anti-Aliasing Filter – Enables AA filtering in the image. When disabled, V-Ray applies an internal 1x1 pixel box filter.

Filter Type – Specifies the filter type to be used for Anti-Aliasing. V-Ray supplies eight types of Anti-aliasing filters: Box, Area, Triangle, Lanczos, Sinc, CatmullRom, Gaussian and Cook Variable. Each has advantages and disadvantages, which make them useful for different tasks.

Size –  Determines the size of the filter in pixels. Higher values yield blurrier results. To produce physically accurate results, the minimum value of this parameter is 1 and the maximum value is 20.
