3ds Max Maps Support (default)

This enables the support of legacy maps (shaders) in MAXtoA. Previously, an environment variable was required to enable this feature. It allows 3ds Max to process the legacy maps for Arnold. One of the limitations is that you cannot feed an Arnold shader into a 3ds Max shader. You can, however, feed a 3ds Max shader into an Arnold shader with this option. Another limitation is that this will not work if you are sending your scene to an Arnold Scene Source file for use as a procedural, or to Kick the file for rendering.
