Prevent scaling of border width/outlines while zooming

Hey guys,

short (nooby) qestion. How can I prevent a border width of a mask prevent from scaling, as I have an animated zoom applied using a transform node.
I am creating a map animation (imported SVGs) and the borders are transparent (using outlines of imported SVGs (unchecked "Solid" and applied a border width) as maks). So the borders are only polylines with a set "Border Width". The whole map is also zoomed during the clip, so I connected a transform node to the whole merged SVG-map stuff. But I don't want the borders to grow, as the view is getting closer/zoomes. Is there a checkbox anywhere I forgot to check, or something?
Thanks a lot guys.

No there is no checkbox that you forgot to check. The border width isn't in pixels, but in percentages.
So if you come closer the border gets bigger.

However there is a way to deal with this.

Right-click your Border Width and select modify with-->calculation.
Then in the modifier panel right-click the first parameter (not sure what it's called of the top of my head) and connect to--> Your transform --> size.

Then set the operator of the calculation to multiply (or divide) and adjust the 2nd parameter to your liking. Now you will have a borderwidth that more or less adapts to your zoom settings. This should - in theory - take care of your line problems.

Come to think of it, it doesn't completely, but I'm not sure why. Math isn't my strong suit
It will get you pretty close though. I'm pretty sure someone else on the forum will provide you with a better solution.

Hey Sander de Regt,
thanks a lot for your kind reply. That sounds like I good solution. I tried it out immediatly. I R-Click Border Widt > Calculation, R-Click the first paramter in the Modifier tab (which is First Operhand, by the way) > Connect to >.... but the contextual menue is empty. Unfortunatelly there is nothing I can connect to. I also tried the other parameters connect to anything, but there is also no choice.
Any idea? Thanks again

You can only connect to things that are already animated. So if you animate the size first, then you can connect to the Transform1-->Size option.

Otherwhise you can make an expression and pick-whip the Transform size by typing = in the 1st operator field. This will create an expression field with a + sign. Click and drag to the size option in Transform and you're good to go. But like I said it's not a perfect solution. But it should help you get started.

Dude, I'm such a donkey, and you are a genius. Donkey, because meanwhile I figured out the must of an animatied node for using "connect to" on my own (after I rashly posted my answer, and that hurts). And genius, because: It works! Great, thank you so much. I can get it rolling right now

But like I said it's not a perfect solution

Anyway, if someone else knows a better, more convenient soultion, feel free to post. For future works I and the community may appreceate it very much. Thanks guys.

I'm also looking into a way of achieving this.

Then follow the steps described in the previous posts and you should be good to go.

I'm new to Fusion, so maybe I'm not doing it right... I'll keep poking around.
