Slider – Adjusting min/max with expression
Hey everyone,
I am building up an effect that is linked to slider controls in After effects; and then make it a preset for future projects; or share with friends or online.
In the expression controller (in this a slider), by default it ranges from 0 to 100. Is there anyway to adjust the min/max like ‘0 to 25′ or ’54 to 67’, etc. But the user can still slide the controls. I remember a website that shows how to produce this but cannot find it.
Kind regards,

I’m not sure, but you may be talking about hacking the PresetEffects.xml file in AE’s Support Files folder. It can be tricky, so I recommend making a backup copy of the file before you start messing with it.

Hmmm, I am not looking to hack the actual After Effect software. Just apply a min/max range in the slider.
Excuse me with my lack knowledge of expression..
min = 10;
max = 50;
... etc.

You can change the slider min and max values by right clicking on the value in the Effect Controls window and selecting Edit Value. Is that what you mean?

Ah yes, that will do nicely! :^) Cheers fella! As I mentioned before, I know it was possible and seen expressions a couple of years ago.
Is there a way to make simple increments like 1, 2, 3 etc; instead of 1.43, 2,67… etc?
Thank you spending the time on this,
Cheers,

You could add an expression like this:
Math.round(value)
but then you’d have to adjust it by scrubbing the value rather than moving the slider.

I thought that was the case, well there’s no big deal really. :^)
Thank you again fella; all the best until next time!+Z
