Since last year, there has already been a “MaxtoA” preview version with which you could use Arnold within 3ds Max. With the purchase of the renderer from Solid Angel, it was only a matter of time before Autodesk announced full integration of Arnold for 3ds Max. For the 2018 release of the 3D software planned for April 12, Autodesk now promises to include Arnold as a free licence. You can read an Autodesk FAQ about the announcement here.
