We’ll have 3D Relief carving in Pro: Relief Carving - Work in Progress
Though what you’re showing there looks more like a moulding toolpath, which is also likely: Moulding Toolpath equivalent in Millmage? - #2 by Colin
For the moment, MillMage has very limited ability to produce smooth output like that - the only real exceptions are fluting, or just using a huge round-bottom bit, but 3D Relief carving will allow carving of depth maps, and then we’ll add 3D model import.
I can also look at what would be involved in doing a moulding toolpath, as that seems like it could be a nice in-between.
