Normal map showing tris issues

[SteveNicholls]

So we import a normal map and we suddenly see this (tri shapes appearing across the mesh)… when the normal map is turned off it is perfectly smooth but all goes to pot when enabled. we are at a bit of a loss on this. Any ideas? thank you

Do you mind sharing the normal map in this topic? Such artifacts can appear if the normal map baking was not done properly.
