I can always 'tell' a Zbrush model rendered in KS. Sure, Zbrush is good for extreme character detailing and design and creating the "ultimate dragon scales," but hard surface modeling? Not so much. My guess is it will be 2-5 years before we start to see acceptable autoretopo tools which need no hand tuning. I believe there will need to be some serious AI work in remeshers before they are able to handle ZB, 3DC and CAD output in an acceptable quad format. Z's topology remesher is not as good 3D Coats, and theirs isn't all that good, IMO. In fact, I recently recommended to Art Center to purchase MoI solely for that purpose as they are wanting to move from Rhino to VR quickly. I know of no other program that can do that.
Still, MoI has an absolute tremendous SketchUp export which when used properly can create very nice and 'renderable' meshes for VR at low poly acceptable resolutions. Mostly, they can be quite difficult to create good UV mappings. MoI and other CAD meshers create "funky" poly meshes, so often there are difficult smoothing and mapping issues to deal with. MoI can actually be used also as a concept modeler as well. IMO, MoI and it's kind are best for accurate CAD, 3D printing (poly modelers pretty much suck at that) and in some cases can be used for VR. If you CAN do it in a poly program, then it's best for VR. Simiilar work is done by Bulgarov and others (see 10 days of Mechs). Of course there might have to be some auto-decimation and baking of normals, but that's trivial compared to the workflows demanded by Zbrush (and 3D Coat) to prepare their 10 million poly models for VR. If you look as some of Jerry Perkins work (aka Masterxeon1001) you'll find similar form development and detailing, but unlike zBrush models, they are already in an optimized poly mesh for gaming or VR. Something like Zbrush still needs hours of retopo in order for it to play at all in those arenas. Now, more than ever, low poly meshes are needed for VR and immersive game and reality experiences. "Will Zbrush kill all Polymodellers now ?!"Ībsolutely, categorically, NO.
