Does Slate support Mask?

We want a progress bar whick is masked to show progress, not scaled! Does any one know this?

Bump…

You you gonna use it in game or editor?

I’m using it in game. I found a solution using clipping. I’m not sure about the effect that OP was trying to achieve, but you can set clipping on the parent pane to one of non-default options and suddenly it’s children will not be visible for the parts that are outside of the pane.
