Dimmer Curve Response

Using a Hog4 console to control Source 4WRD fixtures via DMX.
I'm not getting dipless crossfades (wow, that's feels pretty old school to say that).
The lights are lacking on the low end.
Like they need to be in Square Law response.

Nothing on ETC side about setting dimmer response in the S4WRD for DMX control.
There is info when driving it with actual dimmers.

I know the Hog4 software pretty well.
Can't think of any way to simulate a Square Law.

Am I missing something in Hog4 that can do that?
