ZBrush Panel Loops: A Saviour For Vehicle Concepting in ZBrush?
I’ve got to be honest, I love to work on concept vehicles in ZBrush. It’s easy, quick and gives an artist a huge amount of freedom to develop and change a model without getting bogged down in polygon edge flow, smoothing, creasing and… well, you get the point. It saves a lot of time and hassle, and allows you to produce some really nice work.
Being just as honest, though, I’d almost given up on it. The work is always high polygon, and I always want to take the work into Maya for extra detailing, texturing and rendering: extracting a door from the model, for example, but leaving the edges of the extracted pieces nice and smooth, but low enough in polygons to easily go in and extract edges for body panels around windows, or to have enough, low-resolution pieces to start extracting out the interior of the vehicle. ZBrush didn’t give me that, and drawing new topology over old pieces just left me frustrated and, occasionally, pretty depressed.
Pixologic released ZBrush 4.5 last week, though, and it introduced some cool new features. The most useful for me, that I’ve looked into so far, addressed a lot of the above concerns… and maybe saves me from frustration and hours that seem to produce no solutions.
