- The Draw Size slider sets the size of all brush strokes or editing actions.
Draw Size has a Dynamic mode which will automatically adjust the brush size depending on the scale of the model. Shift+click the word Dynamic on the right side of the slider to turn this option on or off.
- The Focal Shift slider fine-tunes the current painting or editing action. It shifts the effective curve so the intensity is drawn closer to the center (positive value) or away from the center (negative value). This slider simply mirrors the value of certain other sliders: if the current tool is a painting tool, it mirrors the value of the Focal Shift slider in the Alpha Adjustment Curve (Alpha palette). If the current tool is a 3D object in Edit mode, it mirrors the value of the Focal Shift slider in the Edit Curve (Transform palette).
The value of this slider is reflected by the size of the inner ring around the draw cursor: larger/positive values result in a smaller (more focused) ring, and smaller/negative values result in a larger (less focused) ring.
- The Z Intensity slider sets the amount of depth information applied by the current tool or object. Z Intensity is tied closely with RGB Intensity, which has the same effect for color information. For 2.5D tools, the RGB Intensity and Z Intensity sliders are locked together.
- If RGB Intensity is less than 100%, tools apply colors more faintly, blending them with colors painted upon. RGB Intensity is tied closely with Z Intensity, which has the same effect for depth information. For non-3D tools, the RGB Intensity and Z Intensity sliders are locked together.
The Mrgb, Rgb and M buttons determine whether a tool adds color and/or material to the canvas. These buttons are only pressed one at a time.
Mrgb specifies that the tool paints with color and material; Rgb specifies color only; M specifies material only.
If all three buttons are turned off, the tool adds neither color nor material. Depending on the settings of the Zadd, Zsub and Zcut buttons, it will only add depth information to the canvas.
Each tool remembers these buttons’ settings, and recalls them when the tool is selected.
When the Rgb button is pressed only color will be painted – materials will not be affected.
When the M button is pressed only material will be painted – color will not be affected.
The Zadd and Zsub buttons determine how a brush adds or removes material from a model. These buttons are only pressed one at a time. Zadd specifies that the brush adds material, as one would add clay to a model.
When the Zsub button is pressed, sculpting operation occur ‘inwards’, removing material from the model.
Press the Perspective button to apply perspective foreshortening to a 3D object.
Angle Of View
Angle Of View controls the strength of the perspective effect. As with camera lenses, a short focal length gives the strongest perspective, and a long focal length the least.
Align To Object
Align To Object will keep the model’s alignment facing camera when moved to any location of the canvas. If turned off, the tool will have a slight rotation to its alignment as the model is moved to either corner of the canvas.
