Macros: expression based on input measurements?

Hi there,

sturggling at Macros again...

Here's what I want to do: in some Macros, I use generated material (like Background Node) which are, by default, the size of the comp. However we all know that not every input you might want to use is comp-size, and I'd really love to dynamically scale by the measurements of the inputs.

In Nuke I'd use something like "input0.width" and that would work fine, however I didn't really got there inside of Fusion. In worst case I'd have to add the size-controls inside the Macro, but I'd really rather do it more elegant like this.

Any ideas?

Best,
Rick

Morning Rony,

thank you very much for the input!
That's really good news and easy to handle. I don't even need a dummy-node, it's fine using the first node in the chain I think

Best,
Rick


edit
even more elegant: you can set the expression in the generated node (e.g. the background) itself, without the resize. Makes it even more conveniant!
Thanks!

I use the dummy node because i'm used to building macro's and I like to have a dummy input node that I know i can keep in my expression.

In comp. What works is the way to do it
