Basic Padding not working for me

[revilo3d]

I'm Using Houdini 13.

$F works, $F3 breaks. As soon as I add a number after the $F it breaks. I am watching tutorials where they all do this without a problem. Any tips on why this is working differently for me?

Thanks

I don't think $F3 is valid; only $F and $F4. Use the padzero() expression instead.

$F3 should work as expected even if it turns red

just middleclick on the parm label to see how your expressions are evaluated, you should see it return correctly padded frame number

$F<N> for any integer N is valid. You can even do $F200, if you want to get crazy. It's just that we're not special-casing it, like the expression parser, in the syntax highlighting code.

Middleclick reveals what I would expect - and it does work when i create an simple example in a new scene to test - however on several instances it was breaking my geometry writing out wedges and also in other parts of the tutorial. Because of it i just stuck with $F and it would work again, and am unsure in what particular circumstances it was falling me. I'll be sure as soon as I break it again to save the file and post it back here. Good to know about the highlighting
