TB: The nature of the business has changed pretty dramatically. Product has to get done faster and cheaper. Manufacturing costs have been going up steadily. License fees aren't going anywhere but up. The price for doing business, with all the auxiliary costs, aren't going to go down. Something had to give.
When Digital Modeling became a reliable tool, it seemed to help offset and to streamline the most time consuming and critical stages of the process - sculpting. Digital Modeling does some things brilliantly. With movies so reliant on CGI, using those files to create product is a natural. You know what you're going to get from the outset. No guess work. In the hands of a talented Modeler, it can produce quality work. I find that Modelers who sculpt traditionally produce an overall better product. So, as I meander toward an answer - yes, Digital Modeling is replacing traditional sculpture whenever it can. Or, whenever a company thinks it can.
But there's something that happens when you work in a fully real physical space - forming the material, watching it develop - that I don't think is possible using Digital Modeling, at least where the technology is now. When you work in clay or wax, or whatever, you're in a collaboration. You're working it, but it works on you as well. You drag your thumb across a pinch of clay and the way it forms, the shapes it takes, tells, you what to do next. I've worked pieces where the clay was a lot smarter and more perceptive than I was. It's pretty humbling to be outsmarted by a lump of clay.
There's also the advantage of being able to see the piece, physically, in a physical environment. You get to see how it works in space, on a table, next to a window. You get to see what various kinds of light does to it. How its character changes as the light changes. And, I think there's a real advantage to being able to compose in true 3D over virtual 3D. My good friend and brilliant sculptor,
Tony Cipriano has been posting pix of some of his clay work on his Facebook page. They're rough, almost impressionistic and full of life. I have yet to see any Digital Modeling come anywhere remotely close to what Tony can do with clay. Not to put too fine a point on it (although it may be too late for that), what Tony does it art. I don't think at this stage of the game that Digital Modeling is up to it.
