Locking POSITION only

[Todd Kopriva]

Two ideas:

Set an expression on your Position property that defines it as a constant value.

OR

Don’t work with a mask on the layer. Work with a mask on a solid layer above the locked footage layer.

I describe the latter approach a bit in a blog post about rotoscoping, in which I also recommend the Pete O’Connell Creative COW DVD on rotoscoping. (Pete uses this method, too.)

Using the eyeball switch makes it very hard to select the mask nodes (it deselects the mask), I think I’ll try using OPACITY at a very low level instead.

Yeah, because of the particular nature of the POSITION attribute, and the way the user interacts with masks being ambiguous to the application, locking POSITION out would be nice.

I’m on AE7, so a little behind the times…

Take a look at this script, this should do the job for you.
