PivotPainter2FoliageShader Wind Setting

I’ve been trying to utilize the PivotPainter2FoliageShader, but I’m stuck at the Wind Setting part. When I create my Material Instances, the wind settings options are disabled. The documentation states " In order to make use of these, you will first need to enable the Wind Setting for the level(s) that you want to affect" but I have no idea where that is. I’ve looked at the Content Examples and they look to be using Pivot Painter 1 functions with Material Param Collections, but those don’t seem to be compatible with the Pivot Painter 2 Foliage function. I dropped a Wind Directional Source actor, but that doesn’t seem to be compatible either. Can anyone point me to what I’m missing? Thanks in advance.
