 = 3ds Max Design not available.

Mental Ray compatibility in Max 2017 and 2018

From 3ds Max 2017 Mental Ray was an optional installation. Forest Pack for Max 2017 still has many dependencies on the Mental Ray libraries and is required by our plug-ins to operate correctly. Please make sure that Mental Ray is installed for 3DS Max 2017, even if you don't intend to use it to avoid errors.

From 3ds Max 2018 Mental Ray is no longer included, and for technical reasons, we have had to suspend support.
