Enable/Disable All – Each render element can be enabled/disabled individually from the list itself. This option can toggle the state of all render elements at once, but only affects production rendering. Enable/Disable All in IPR – Toggles the state of all added render elements at once, but only affects IPR sessions. Separate folders – Exports each render element to a separate folder based on its name. Get name from node – When enabled, V-Ray will use the name of the render element nodes when saving render element images. This allows the user to name render elements directly through the render element nodes instead of only through the attribute editor. Separate RGBA – Specifies whether the main RGBA element will go into a sub-folder too if Separate Folders is enabled. Use referenced – Toggles the use of render elements from referenced files. Unfiltered fragment method –Specifies how to determine the final values for render elements where filtering is turned off (i.e. Z-depth, object ID etc.). This option is not supported when working with the V-Ray GPU render. Best coverage – For each pixel, the final values for the render element are taken from the object that has the largest contribution to that pixel. Closest to camera – For each pixel, the final values for the render element are taken from the object that is closest to the camera. Render element separator – Separator character used to construct the render element image name. Deep merge mode – Controls the generation of deep data for deep OpenEXR 2 and VRST files. Normally with the default setting of By render ID, V-Ray merges the deep fragments that belong to a single object within a pixel in order to reduce the size of the deep data and also to allow for the perfect separation of the different objects if needed for post-processing purposes. However, especially in cases where you have one single object with a complex shape (i.e. one VRayMesh node that represents a large portion of the scene environment), this may be undesirable and so you can change this behavior if you set the deep merge fragment mode to By Z-depth. This will cause V-Ray to separate the deep fragments based on the similarity of their z-depth values rather than which object they belong to. The deep merge ZDepth threshold parameter specifies how close the deep fragments need to be relative to the pixel size in order to get merged, which essentially allows you to control the precision vs size of the deep file. This option is not supported when working with the V-Ray GPU render. By render ID – Deep fragments within a pixel are merged based on which objects they belong to (objects are differentiated based on their render IDs as they appear in the render ID element); By z-depth – Deep fragments within a pixel are merged based on the similarity of their z-depth values. Use the Deep merge z depth thresh parameter to control how close fragments need to be in order to merge them. None – Deep fragments within a pixel are not merged at all. This mode preserves most sampling information; every single image sample is stored separately and this usually results in very large deep files, therefore it is best to use only when the other modes are not producing satisfactory results. By render ID and z-depth – Deep fragments within a pixel are merged if they share the same render ID and are within the Deep merge Zdepth thresh. This is a combination of the other two modes. The By render ID mode allows you to extract masks exactly, but for an object with a complicated shape it doesn't distinguish between overlapping portions of the same object. The By z-depth method separates the samples depending on their depth, but does not allow clean masks. The combined mode separates the deep points based on both render ID and z-depth thus solving both problems simultaneously. Deep merge zdepth thresh – When deep merge fragment mode is By z-depth , this threshold controls how close the fragments need to be in order to merge them. The value is relative to the pixel size. A value of 1.0 means that fragments that are within a block roughly the size of a pixel will be merged together. Lower values produce more precise deep data, but can lead to larger files. Higher values make the deep data less precise but can make the resulting deep files much smaller. A value of 0.0 will store every single image sample separately and is strongly discouraged. This option is not supported when working with the V-Ray GPU render. Exclude RGB from deep files – When enabled, the RGB channel will not be included in deep files. This option is not supported when working with the V-Ray GPU render. |
