This release of MAXtoA does not include support for all Arnold or 3ds Max features. See the online documentation for further details.
Arnold 5 adds the new data type "closure", and shaders that return closures will now show up in 3ds Max as materials instead of maps. Due to this and the large number of other changes in Arnold 5, scenes made in 0.9.608 or earlier (for 3ds Max 2017) are not supported, and will load with many warnings about missing shaders.
Some shaders have been removed since version 1.0.712, and these will be reported as missing upon load.
