Glass Distortion controls
• Softness — controls the transitions between displaced colors
Increasing the Softness setting creates more intermediate steps, which produces a smoother distortion.
If you experience aliasing in a glass distortion, try increasing the Softness setting.
• Refraction (Map type) — displaces pixels in the same way that an optical lens bends light. This is the
best map type for creating distortions that you’d expect from looking through glass.
• Vector Displacement (Map type) — moves pixels in a specific direction
• Angle Displacement (Map type) — moves pixels in different directions. Increasing the Softness value
by a small amount (from 0 to 0.1) with this map type produces dramatic changes in the glass distortion.
• Amount — controls the degree of displacement. Moving the slider to the right increases the distortion.
