Painting flow maps / normal map blending issues

I made a fur material in Substance Designer that orients itself using a flow map, painted on the normal channel following this guide on the official documentation.

However, there is a massive issue with painting anything on the normal layer, as whenever you paint anything on a normal layer it stacks up with whatever is being painted over rather than replacing it resulting in an absolute mess that completely breaks the material taking information from the normal channel.

 

The question is, is there any way to prevent this from happening and force the paint layer to replace whatever is at the bottom OR use any alternative methods for painting down the flow maps?

I can confirm this seems whole workflow seems very broken. I last tried it a year ago and I had the exact same problems. When will it get adressed?

What are your stroke flow, stroke opacity and brush hardness settings?

It's set like that already, the problem isn't painting on a layer above the normal map, the problem is that whenever i paint a stroke in the normal channel then paint another right above it in the same layer, the new one blends with the underlying one rather than replacing it, and this breaks the flow maps completely

Change the blend mode of the normal channel in your painting layer from NMdt to Normal, or Replace depending on exactly how you are using it.

 

Do that in the layers panel after selecting Normal at the top left of the same panel
