Curve parameter can't change atlas?

I realize the node is called “CurveAtlasRowParameter” which may imply that you can only change rows, but I still find it a bit strange and limiting, especially since I put my curve in a material function that I want to re-use quite a lot…

So, here’s a very naive newbie question, but if two different DLCs for my game want to use this material function, I must update the core game (atlas) with all the different curves from both of them?

EDIT: Bonus question… why do I get a float parameter together with the curve in my material instances? They toggle on and off together for some reason too…

EDIT 2: Bonus weirdness… moving a curve point doesn’t live update the viewport, but moving the handles do…

still wondering what that float parameter together with the curve do… :upside_down_face:

Ditto - Not sure why the ability to Swap the Atlas isn’t an option here or in a different node - is there something obvious im missing?

Im using Atlas Rows as a Custom Primitive Index, and rather than duplicate my master to just change the atlas, Im wondering if there’s a more efficient process
