RE:Flex for combustion is a great plug-in that provides warping and morphing tools for your videos.
RE:Flex for combustion is very easy to use: simply select the source and target geometry (no meshes are required).
Here are some key features of "RE:Flex for combustion":
· Warping is directed through the host program's roto tools (splines and polylines), not through a grid of mesh points!
· Geometries need not be closed shapes
· Smooth non-polygonal warping
· Interactive warping: view the warp as you drag the control shapes
· Option to match vertices of corresponding geometries for fine control
· Combustion 3.0 and up
