Introduction to Zbrush Digital Tutors
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.
– pixols can be tranformed using the Move, Scale and Rotate buttons. Select Draw to continue drawing in 2.5D.
– use EraserBrush to remove pixols from the canvas.
– materials and colours can be changed during the drawing to overwrite pixols already on the canvas.
– 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.
– 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
– SphereBrush always paints with a perfectly round edge, which can be made larger with more pen pressure or larger 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.
– 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.
