Until it’s out I’ll have to assume that Morph3D will offer the same level of usability as DS does. The only flaw with DS at the moment is it has a very high learning curve equal to UE4.
There is also an export/import bug at the moment that one has to take a detour through 3ds Max that is preventing a direct DS > UE4 pipeline but once fixed but once again once fixed I would assume that Morph3d would also offer the same tool sets DS has to make any changes you wish.
