Live slider control of HDA parameters ?

Hello ,

Is there a way to “promote” some parameters of an HDA to UNREAL, so that the user in a game finds a slider or some kind of control that would modify this parameter for “LIVE” interaction, for example; deforming an object along a curve using a bulge SOP, but with the gamer in control of this deformation during the game?

Thanks you for any hints!

Have a good one!
