ZBrush Panel Loops: A Saviour For Vehicle Concepting in ZBrush?

Posted in 3D, Design, General, Pictures, science fiction, scifi, Tutorials, zbrush with tags , , , , , , , , on January 1, 2013 by Jim St Ruth

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.

Sculpted, retopologised and textured in ZBrush 4.5.

It’s been a little while since I last posted; I’ve been busy writing my next book and looking for a potential agent for my first novel (which I should hopefully get sent off soon).

I thought it would be good to post a few images: the first two are of my latest project, including the original sketch and the Zbrush sculpt so far, the third image is of a slightly old project that I’ve drawn a line under. I’d done as much as I wanted to and, to be honest, I used it mainly as a means to progress my sculpting, texturing and retopology skills.

Clothes and retoplogy were all done in Topogun; an excellent program in every respect. It makes the job of producing new geometry so much easier than using Zbrush’s own zsphere method of retoplogy; it’s easier to see what’s going on, and far easier to draw out new polygons over your old mesh.

Much was achieved here thanks to a two month subscription to Digital Tutors; an excellent group of people that clearly know what they’re talking about, and that have a brilliant set of training skills. I highly recommend any aspiring 3D or 2D artist give them a look.

Zbrush itself has come on leaps and bounds over the last few years. I’ve been using it since my partner, family and a few friends clubbed together to buy me a licence for my birthday and, amazingly, it not only comes in at a reasonable price but each and every upgrade has been at no extra charge. Over the last two releases Pixologic has really worked hard to introduce and develop their Fibremesh system; a very easy way to create and style hair, fur, grass, trees… the list goes on. Digital Tutor’s have produced some excellent courses designed to show how to style hair and fur; before I watched their videos I just couldn’t get the hang of styling at all.

So a big shout out to Pixologic and Digital Tutors in particular… long may you reign!

Space Man WIP: Update

Here’s an updated to my Space Man project; now with texturing, materials and hair. The materials were made with Zbrush’s excellent Matcap feature; the first time I’ve ever used it, and a great way to get the cartoon-esque lok that I’m after.

Zbrush Does Hair!

Zbrush 4R2b has been released with the amazing addition of a full fibre creation system… that means hair, grass and just about anything else that you could thing of in a fibre-related way.

The system is easy to use; just mask off the area of your model that you want to apply hair to, and then use the ‘FibreMesh” drop down to start creating. It’s easy to style the hair too, and during my limited tests I’ve been amazed.

Check out my test renders below.
