Corner pin question

Hi guys,

Am doing some corner pinning and cant remember something that came in real handy....

What is the cheat to make the transform tool in the corner pin node rescale to the size of the image?

At teh moment I am trying to skew in a multiplane but because the image is so rescaled it is tiny and the corner pin tool is massive in comparison making it hard to be accurate.

Am sure i used a tip once where you put in two corner pins and do some kind of invert or something to make it work real nice...

Anyone know this tip?

Assuming that you are working with CornerPin1,
create a new node called CornerPin2 that is not connected to anything.

Back in CornerPin1, create a Local Variable named "scale".
For now set it to something like 4. You can adjust this later.

For each corner parameter of CornerPin1 change its value like this:
Replace x0 with CornerPin2.x0 * scale
Replace y0 with CornerPin2.y0 * scale
Replace x1 with CornerPin2.x1 * scale
etc.

Now you can load CornerPin1 in the Viewer,
and load CornerPin2 in the Parameters tab.
Adjust CornerPin2 while you look at CornerPin1
