I agree with Jonathan,
clients or in my field stage directors, get too flustered with nice renderings that look too complete for the early stages of the design process. They think 'this guy has spent too much time and effort into the design, I hate to ask him to change it....' While it has taken me no time to create a 3D model with true textures...
And I hate that too, since I want to purse the look more. Now they see that it's in the 'sketch' phase of the process, and think that's it's not complete.....
Another addition to a great program.
Thanks,
