RE:MAP TUTORIALS
Part 3: Displacement Mapping
In After Effects, open REMAP_3_Displace.aep. These projects should be run in 16 bit per channel.
For non AE users, there is a screen snapshot (UI snapshot link) for you to view the settings at each stage. Just retyped the same values as shown. In the ExampleMoviesAndImages folder you will find: the color source (curbecolorcolor.####.jpg used in the first example and smallTestMovie.mov used in the second example). For the first example we also use Displace1DispMap_####.psd as the displacment map and Displace1DispMod_####.psd for the modulation control sequence. For the second example we use Displace2DispMap_####.psd as the displacement map.
This set of tutorials play with the displacement controls. The objective here is to walk you through the controls. This complements the documentation which describes in detail each controls. The documentation PDF came with the product installer.

Project: Displace 1 - UI snapshot
The Modulation Channel
Here we apply a displacement effect that effects only a part of the image. For the sake of this tutorial, we created a full on red and green channel (which means a motion toward the upper right corner). In the Blue channel we created a wave animation. Notice in the “Displacement Controls”, we have set the “Swap Inputs” to ON.
Things to try: * Twirl open Modulation Controls. Turn the Modulation Channel from Blue to Off and back to Blue * Raise the Warp Amount, see there is a bit of aliasing, set the Mip-Map Method to Smoothest |

Project: Displace 2 - UI snapshot
Creating a Displacement Map
Here we simply animated a circular ramp maintaining the center of the ramp about where the person nose is. If you look in the Displacement Controls, you will see that Vector Scale X is at 2.56 and Y at 0.0, telling the effect to do only the effect horizontally. In this case this is what we want as the actor’s motion is going from the left to the right.
Things to try: * We are using Forward Mode. Set Passes to 1, then back to 2 * Set X and Y Scale to 1.0, go to the middle frame and play with the rotate slider |
