PRISM DISPLACEMENT

Prism Displacement distorts and displaces the pixels in your image with a prism-like, chromatic effect based on the luminance values of another layer.

Getting Started in a timeline       

1. Add video layers in the timeline for the displacement source and the image to be distorted.
2. Apply uni.Prism Displacement on the layer you want to be distorted.
3. Use Displacement Source to choose the video layer that you want to guide the luminance displacement.

Getting Started in a compositor    

1. Apply uni.Prism Displacement on the layer you want to be distorted.
2. Use Displacement Source to choose the footage layer that you want to guide the luminance displacement.

Modify the Effect

• Presets are available to set the levels of displacement, or you can modify the settings yourself. 
• In the Source drop-down, you have three options to guide how you want Prism Displacement to view that source: as a Luminance map, an Alpha (premultiplied with Gray) or as an Alpha (premultiplied with black). Default settings begin with 50% gray areas as neutral, with white and black areas distorting the footage.
• Glass Refraction gives you a slider to control the amount of glass refraction happening.
• The Refractive Index is a multiplier to the Glass Refraction.
• Soften Displacement Map allows you to blur the edges of your map.
• The displacement amount of the Red, Green and Blue channels can be split individually by changing the Refraction Settings for each color.
• If you want to adjust the input levels of the displacement map colors, adjust the black, white or gamma levels using the Displacement Map Levels.
• There is a section giving you control on the Lighting that hits your displacement, allowing you to position the light in X, Y and Z, as well as adding a diffuse color. 
• Stretch Map to Fit will force the displacement map to match the source image size, and is on by default.
• Bicubic Sampling gives a slightly slower, but more accurate, sampling method.
• The Wrap Mode shows options for extending edges of the image if the distortion changes the image size (Border, Repeat, Mirror, Clamp).
• Check View Displacement Map if you want to see the map being used without turning off your source layer.
