Generator Effects

Generator Effects

The Generate section of the image effects, contains a set of image generator effects, creating synthetic images from effect specific parameters. These effects can be used to create new synthetic images and textures.

Some of these effects, add the synthetic image to the existing image, creating various composition effects.

Brushed Metal

The Brushed Metal image generator effect, creates a brushed metal surface fill over the object image, using the object alpha mask. The brushed metal effect is generated in the selected direction, and optionally may use noise to adjust its strength.

The Brushed Metal effect and its options.

Advanced options of the Brushed Metal effect.

The Brushed Metal generator effect uses the following basic options:

  • Color - Select the color of the brushed metal effect. The brushed metal surface is generated using shades of a single color.
  • Strength - Set the strength of the brushed metal effect. The strength adjusts the intensity of brush tracks along the selected direction.
  • Angle - Set the angle of the direction of the brush tracks.
  • Variation - Set the amount of variation in the strength of the brush tracks.
  • Seed - Set the randomization seed used to generate the brush tracks. The button can be used to pick random seed values.
