Am I missing something or is there no good / easy way to do render with Tangent Space NormalMaps ?

I found this asset on Orbolt but that seems slighty broken since H12.5:
https://www.orbolt.com/asset/_slayerk::ZBrushTangentNormals [orbolt.com]

And this on the old Exhange but also seems broken:

After further googling I came up on this thread at oddforce and a solution.
