Normal map - weird reflection

Tininio

Hello !

I had some weird reflexion inside Marmoset and 3dsmax viewport when I apply my normal map.
this pattern isn't inside my normal, but when I push specular/gloss It appears on my mesh, if anyone has some knowledge to share about, that was pretty save my little life !
Thanks and sorry for my English ...

As a quick test, try baking your normal map in TIFF format.  If the banding disappears, then the link above is relevant and you should give it a read.
