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.
Re-translate Scene on a Frame Change
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.
