Placing Lights

From ZBrush Info

The placement of lights can be adjusted in the Placement subpalette.

P: Click and drag from the position patch to the canvas and release to place a light. You can also enter the position of the light numerically with the Pos sliders.

---

X Pos / Y Pos / Z Pos: Use to set the x, y, and z positions of the selected light.

All three sliders above use a coordinate system where 0,0,0 is the center of the canvas. The X and Y values of +1 or -1 represent the outermost edges of the canvas. Z has a range of +4 to –4 because the total depth of the canvas is four times its greatest X or Y dimension. Thus, the default position is at the exact top center of the canvas and 1/4 of the total scene depth away from the camera.

Placement modifiers are disabled for sun lights, since they have no position.
