MaxtoA System settings (Render Production)
This tab allows control over various Arnold system settings.
The size of the image buckets. The default size is 64x64 pixels, which is a good compromise; bigger buckets use more memory, while smaller buckets may perform redundant computations and filtering and thus render slower but give initial faster feedback.
Enables/disables bucket corners. The default is "on" for production and "off" for ActiveShade.
If enabled, the scene is re-translated from scratch on a frame change, when rendering a sequence. By default, from frame to frame, MAXtoA re-translates only the elements that changed, but there could be cases where these elements are not detected correctly. This new option simply re-exports all to Arnold, of course at the cost of the full scene translation time.
Uses the Arnold RenderView by default for all new scenes.
If autodetect is disabled, this will let you manually set the number of rendering threads. Negative numbers are also allowed. If specifying 0 threads means use all cores on a machine, then negative numbers can mean use all but that many cores. For example, threads=-2 means use all but 2 cores, while threads=2 means only use 2 cores. This is useful when you want to leave one or two cores for other tasks. One example of this is so that 3ds Max can be more responsive while Arnold is rendering in the Render View.
