On Substance Painter, the This shader allows you to create and check FlowMap.

• PBR_FlowMap This is a PBR-based flow map. However, I'm using the normal map for the flow map, so The normal map is not available.

• Albedo_FlowMap This is a flow map of the albedo map only. It's easy to check the flow because it doesn't contain any superfluous elements.
