Incremental changes are the scene modifications between the first frame and each successive frame of an animation. mi filename used for each option varies and is as follows: mi file per frame not using incremental changes. mi file containing the whole animation, exploiting incremental changes mi files of ASCII format only.Д¬ontrols per-frame. This feature improves the readability of your file.

Use this option to set the number of space characters used to indent lines in your. If not specified, the scene name is used.Д®xport. path/to/Maya/bin/Render -r mr -v 5 -x 1 -uq 1.25 old_2012_sceneFile.ma If you set -sampling 0 (unified sampling), or do not set the -sampling flag on pre-Maya 2014 scenes (in which case Unified Sampling is used), you can also set the Unified Sampling Quality using this flag. path/to/Maya/bin/Render -r mr -v 5 -proj /path/to/proj -sampling 2 sceneName.ma To render legacy scenes with their previously-saved legacy sampling settings using the command line renderer, use this flag with the following arguments: Some features, such as contour rendering, are not supported with Unified Sampling. If you open a pre-Maya 2014 scene that renders using the mental ray for Maya renderer, your sampling settings are changed to use Unified Sampling. This feature is only available for batch rendering. If mental ray does not render your animation correctly, use this flag to re-translate the frames from scratch. Select this option to include all renderable dependencies and render targets in the batch render. Select this option to perform a 3D render and render only the dependencies in your scene. Select this option to perform a 2D render and render only the render targets in your scene. Specifies a bake-set to include all objects not assigned to any other bake-set in the scene. Set sub- region pixel boundary of the final image (left, right, bottom, top). If true, mental ray renders almost everything on slave machines, thus reducing the workload on the master machine. Set the pixel width and height of render tiles.Д®nable this option to automatically determine the optimal tile size at render time. This feature can be enabled at all times to obtain better performance. A soft limit implies that mental ray may actually use more memory than indicated.Д®nable this option so that Maya dynamically calculates the memory limit prior to the start of rendering. Soft limit for the memory used by mental ray (in MB). Enable this option so that Maya automatically calculates the number of threads that should be used to best take advantage of the CPUs (or cores) on your workstation.
