Hi folks, I've got a vellum sim of scattered strings that have an animated falloff mask attribute [i.imgur.com], that wipes from right to left.

I want to get dopnet's popcurveforce to pull them in as the mask moves. Although the mask attribute is detected, it's stuck to the first frame [i.imgur.com].

Any way I can get this to update per frame so that popcurveforce [i.imgur.com] reads it?

You need to update the attrib inside the solver. Fetch whatever attrib you want to use and update.
