How to activate "Flow Map Grooming"?

Question

Howdy,

I'm using this resource (Shaved Hair Material) from the substance 3D asset store in 3D Painter.

It has an option for "Flow Map Grooming" which I assumed meant you could feed a flow map to control the direction.

Problem is, I have no clue how to feed a map into this material.

My questsions are:

Is this feature meant to be useable in Painter, or would this be activated in Designer?
Is this meant to take in a flow map, or is it saying it will generate a flow map ( I assume if you painted with the material on a brush instead of loading it in as a fill)?
If it's meant to take in a flow map inside of Painter, how do I plug a map into this material?

I've attached screenshots of the Properties panel when its in fill mode. Of note, there is nothing listed under "Image Inputs" when it's opened.

Thanks!

HiIf you look at that material in Substance Designer, the button activates an input called Flow_Map with a usage of 'flow_map'. So you are correct in your expectation that the button is activating an input to teh material. At present though I cannot see a way of getting a channel to feed into that input map. There is no dedicated flow_map channel in Painter. The Painter documentation confirms this (no dedicated channel) and whilst it gives instructions on how to paint a flowmap onto a normal channel it does not show how to get that into the material input.https://substance3d.adobe.com/documentation/spdoc/flow-map-painting-143327274.html So I would love to be proved wrong, but at present it looks like a material input made in readiness for a future channel.
