In Mixer, you can paint on your Mix when using a Paint Layer or a Paint Mask. When either of these are added to your Mix, a Brush Panel will appear on the left of the workspace.

Brush Panel

Once you’ve added a Paint Layer or a Paint Mask, a brush panel will pop up on the left side of the viewport. By default, the brush tool is selected in the brush panel (Shortcut: B). Click the eraser icon to switch to the eraser tool (Shortcut: E).

Brush Shape

You can select a brush style from this panel according to your painting requirements. You can load a custom shape to use it as a brush and save it in your Mix as well as delete it.

Brush Library and Properties

  • Brush: Choose from currently available brushes. More brushes can be added from the Megascans online library.
    • Click the square brush image to load a custom brush.
    • Save the selected brush with current settings to your library or delete the selected brush.

When using the default circle brushes, these additional settings are available:

  • Softness: Vary the radius of the maximum intensity.
  • Center curve: Control the curve along the brush.
  • Base curve: Control the curve along the base of the brush.

Brush Jitter

Flow Jitter: Adjust the speed of jittery effect produced while painting.

Brush Settings

  • Size: Control the radius of the brush.
  • Spacing: Set the spacing between successive brush marks within one stroke.
  • Angle: Set the brush angle when painting in Mixer’s viewport.

Colors

Control the Diffuse, Specular, and Roughness here. Mixer allows you to set reflectance values in order to paint on the surface according to your requirements.

Reflectance Preset:
The hamburger menu on the top right of this section has built-in presets. You can select any of the preset and paint on the surface.

Displacement Painting:
You can also paint displacement on the surface by enabling the displacement control. It gives you further options of Raise, Lower and Set displacement. You can toggle between these displacement forms by using shortcut keys Z and X.

Painting a Straight Line

Paint in a straight line by holding Shift (canvas-aligned) or Shift + S (camera-aligned).
