RE:Flex Tutorial File: SimpleWarp

The first thing to notice when you open this project is that there are two compositions: 1) Bulging Eyes and 2) Smile. These compositions illustrate the trivial use of RE:Flex Warp.

1) Bulging Eyes

When you open the composition, you'll notice that there are 5 masks. Two are the "from" geometries for the eyes, and two are the "to" geometries. The last geometry is a boundary which limits the warp.

Bulging Eyes composition.

Note that the masks are listed in pairs, and the ordering is important. The first mask is a "from" geometry, the second mask is it's corresponding "to" geometry, and so forth. The last mask is specified as a boundary geometry in RE:Flex Warp's settings, and is ingored as part of RE:Flex Warp's "from" and "to" geometry list.

When we apply RE:Flex Warp with the yellow mask set as the boundary, we get the following result:

Application of RE:Flex Warp, yellow mask is boundary.

Because RE:Flex Warp ingores the last mask if it does not have a matched "to" mask, try turning the Boundary to "None" is RE:Flex Warp's settings. The warp is not bounded and now produces a bulging head in addtion to the eyes.

Application of RE:Flex Warp, no boundary used.

FOR YOU TO DO: Set the boundary to "None" in RE:Flex Warp (while at the end frame). Note that the head bulges in addition to the eyes.

FOR YOU TO NOTICE: Over the course of the sequence we have animated the green "to" mask in order to produce the animation.

2) Smile

When you open the composition, you'll notice that there are 3masks. One is the "from" geometry for the mouth, and one is the "to" geometry.. The last geometry is a boundary which limits the warp.

Before application of RE:Flex Warp.

After application of RE:Flex Warp.

FOR YOU TO NOTICE: Over the course of the sequence we have animated the Percent Warp setting of RE:Flex Warp instead of animated the "to" geometry.

FOR YOU TO NOTICE: The "from" and "to" geometries are open curves, and do not have the same number of control points. RE:Flex Warp matches the endpoints, and then evenly distributes the matching of the curves along their length (it does not do control point matching along the curves).
