I'm sure you've seen my recent posts about the theatrical set. I ended up abandoning the project for now, because I must get other things done. Another gentleman tried to pick up on IM where I left off, but gave up after two days of effort. Again, he felt he could be more productive in Maya. However, the way I understand how he would do it in Maya (using orthographic photos) the accuracy would just not be there. But, I know almost nothing about Maya.
But, of course, all programs have their strengths and weaknesses. Maya may be easier to use for a face shape where you don't need high accuracy. Please keep us updated.
