The texture should use the screen mapping type. Pixels with any other values are rendered. Black values in the map define pixels which are not rendered. This feature works best with the V-Ray Frame Buffer as the render window and Type set to Bucket. Render mask – Enables the use of a render mask to determine which pixels of the image are calculated. Note that re-rendering the same frame produces the same result in both cases. Since this may be undesirable in some cases, you can disable this option to make the sampling pattern change with time. Lock noise pattern - When enabled, the sampling pattern is the same from frame to frame in an animation. For more information, see the Bucket Image Samplerpage.

For more information, see the Progressive Image Sampler page.īucket – Takes a variable number of samples per pixel depending on the difference in the intensity of the pixels. Progressive – Progressively samples the entire image and refines the details over time. Depending on this choice, an additional rollout opens up below the Image sampler (Antialiasing) rollout with specific settings for that sampler type.

UI Path: ||Render Setup window|| > V-Ray tab > Image sampler (Antialiasing) rollout ( Renderer set to V-Ray) V-Ray includes two main image samplers, each with its own approach to sampling and its own parameters: Progressive and Bucket. To determine the right color for such a pixel, V-Ray looks at (or samples) colors from different parts of the pixel itself as well as the pixels around it. But within a single pixel there might be multiple colors, which may come from multiple objects whose edge intersect at the same pixel, or even difference in brightness on the same object due to changes in object shape or falloff and/or shadowing of light sources. To get the color of a pixel, V-Ray calculates it based on the object's material, direct light striking the object, and indirect lighting in the scene. In V-Ray, an image sampler refers to an algorithm for calculating a pixel's color based on the colors within and around it.Įach pixel in a rendering can have only one color.
