It supposed to be the tangent normal map. That's why i don't understand why i got all this colors. And apparently when i import all the maps i created with this baking, my materials are doing crazy things in substance painter too. i don't understand where i did a mistake :'(
Thank you all for your comments. I tried to do my baking in substance but i got the same type of strange normal map. So i suppose that i did a mistake in my mesh but where ? :'( This is my High poly in Zbrush This is my low poly in 3Ds Max This is my settings in Marmoset
