I'd like to share with you a few more tricks and issues of using the Puppet Pin tool …with layers that have complex Alpha channels.…I've closed my other compositions and if you have access to the Exercise Files,…open up 08-Multiple Shapes*starter.…This line of text has what I would refer to ask a complex alpha.…I'll turn on the Transparency grid so that you can picture it better.…Each character has its own Alpha separated from the other characters.…Also the letter "i" has separate Alphas defining the dot on the top and the body of the "i".…
When you select a layer and then select the Puppet Pin tool, and I'm going …to make sure the Mesh is turned on so you can see it, and use the default …for Expansion and Triangles.…After Effects only looks at the Alpha channel enclosed by where you click.…It does not search for any other little snippets of Alpha channel that might exist …elsewhere on that layer.…Therefore, when I click the inside of the "r" only the "r" got the mesh.…This sort of isolation can be a good thing or a bad thing, depending on what you intend to do.…
