ZBrush Usage Questions
#1

Hey everyone!

I’m doing some work on a book cover, and I’m trying to make make a shape that has proven to be harder than it looks.
I need to make a triangle out of triangle-shaped bars… This is hard to explain, so I’ve attached a quick little sketch of what I’m trying to achieve.

I’ve tried making a triangle shaped alpha to mask onto shadowbox, however i can seem to polish the edges to make it look like its triangular bars… I tried making triangular bars, and use transpose to move them into position, but still, that looked like crap too…

Any help?

Unfortunately, I dont have maya or really any other 3d program other than zbrush and blender.
I love zbrush, but havent had luck with this type of hard surface work.

…there has to be an easy way to create this shape…
Anyone?

Off the top of my head:

Start with a poly cylinder. turn on Radial Symmetry at 3 around Y. Use one of the polish, flattening or even Trim brushes . Duplicate subtool and scale it to the size of the inner whole. Use the boolean feature to cut it out of the original subtool.

Hope that helps…

I would do it this way.

Cylinder3d - Initialize - HDevide 3 - make polymesh and cut the edges with the slice curve

I suggest you start with a Ring3D, Initializing it so that SRadius is 60, Coverage is 360, Scale 1, Twist 0, SDivide3, LDivide3 and ITwist 30. Deformation/Rotate it by -30 in the Z axis and Size it by -100 in the same axis.

This produces a perfect, triangular-cross-sectioned triangle.

Rory,

OH MY GOD YOU HAVE SAVED MY FROM PULLING THE HAIR OUT OF MY HEAD, ONE STRAND AT A TIME!
Thank you so much for replying to my post!
Simple, easy, straight forward, I very much appreciate the step-by-step.

May I ask, how would I go about doing the same thing with other shapes…
Say… A hexagon, made of hexagon-shaped bars?
Is it just a matter of the SDivide and LDivide?

Thanks again,
Corey
