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.

First Zbrush 4 Head Sculpt – And a Quick ‘How To’

I wanted to share my first Zbrush 4 head sculpt, created using Shadow Box. I’ve included some images below, designed to give a general view to the process for those of you not familiar with Zbrush, rather than as a tutorial. What impressed me most about Shadow Box was the speed at which you can create a general form that you can use as a base object to sculpt on – and not just heads or figures, but hard body objects like cars, weapons, armor – you get the idea.

I also used the new Clay Buildup brush to add increasing levels of detail on the basic form. It’s so easy to use and, as you subdivide the jaggedy appearance of what you’ve sculpted is smoothed out, but not the overall shapes.

The above image was rendered using Zbrushes new Best Preview Render, with shadows and ambient occlusion added. With a whole laod more options, tools and brushes, I can see that Zbrush is going to keep me busy for some time.
