Day 2

Introduction to Zbrush Digital Tutors

Basics of creating Geometry

– To view a wireframe on the mesh, tranform > PolyF or Shift + F or PolyF button on the right shelf.

Different ways to enable a polyframe

–Primitives can’t be sculpted but can be transformed while in edit mode. To see options go to tool > Initialize which will display options relating to that primitive eg initial size and resolution.

Initialize settings can be used to modify primitives before converting to polymesh for editing.

– Coverage is what angle the primitive is filled to in degrees.

– TaperTop and InnerRadius can turn a Cylinder into a hollowed flat cone.

– Twist can turn a Ring into a ribbed pipe.

– SweepProfile can create some interesting curves which are further modified in the Initialize palette.

–Helix3D can be used to create eg suspension springs that vary along the length.

– Gear3D has a lot of options and can create very intricate shapes and features for other models.

– Lightbox (,) is where you can find imported tools, projects, materials, alphas and brushes.

– if a tutorial uses a non-standard sculpting brush it will likely be found in lightbox eg TrimHole.

Lightbox provides quick access to lots of important items.

Pixols and the 2.5D canvas

– a pixol is a pixel that contains colour, depth, and material information.

– open the tool quick menu to select 2.5D brushes. 2.5D brushes can have strokes and alphas applied to them like sculpting brushes.

open the tool quick menu to see the 2.5D brushes.

– pixols can be tranformed using the Move, Scale and Rotate buttons. Select Draw to continue drawing in 2.5D.

Pixols drawn on the canvas can be transformed using the move, scale and rotate tools

– use EraserBrush to remove pixols from the canvas.

Use the EraserBrush to remove pixols from the canvas.

– materials and colours can be changed during the drawing to overwrite pixols already on the canvas.

the material and colour applied to the pixols can be changed during the drawing.

– disable Zadd / Zsub during the drawing to avoid adding depth to pixols already on the canvas, only painting with colour and / or material.

– Mrgb allows for changing colour and material of pixols on the canvas without affecting depth.

–RGB allows for changing colour of pixols on the canvas without affecting depth or material.

– Mrgb / RGB buttons can be disabled entirely to allow drawing depth without affecting the colour or material of the pixols.

Use combinations of ZAdd/Zsub, Mrgb and RGB options to draw with different depth, colour and material affects.

– Document > Save As saves the canvas out as an image, not a 3D model.

– SnakeHookBrush allows for dragging out tendrils with depth.

– FibreBrush allows for covering pixols in fibres / hair

Other brushes can be combined to get interesting 2.5D effects

– SphereBrush always paints with a perfectly round edge, which can be made larger with more pen pressure or larger strokes.

The SphereBrush with different strokes.

– AlphaBrush draws in the shape of the current Alpha at a single depth until a new stroke is started.

– Smudge brush can be used to smear pixols around on the canvas. Combining different strokes and alphas will give different effects.

Different effects using the Smudge Brush with different strokes and alphas.

– Hook Brush can be used to pull pixols out. LMB + Anti-clockwise spirals shrinks the pixols, while LMB + Clockwise spirals enlarges them. Hook Brush can be combined with alphas for different effects.
