Normal Map baking Issu / Artefacts sd

Drakoliche

Hello Everyone,

I'm actually in front of a problem, when i baked a normal map in Substance Painter 2 i got this :

It's pretty good , but when i make a render in SP or when i export the normal map in unity i got this :

Some square artefacts appear but i don't know from where. When i reduce the quality of the normal map the squares artefacts are bigger.

I've search everywhere but i didn't find a good answer, i tried to triangulate my mesh before import in Substance but that didn't work, i tried to change every parameters of Substance Bake, but nothing seem to fixe this problem. So if you can help me, I'm open to every solutions.

Thanks for your comprehension,
Drakoliche.


PS: It's possible that is the wrong forum for my problem (Technical Talk can be better), so I will repost this topic in Technical Talk forum, sorry for the trouble.

Hi,

Thanks for you answer, i already had see this topic, but after read it few times and try everythings, i have successfully reduce the artefacts.

If that can help someone else : i forgot unity have in default setting a pre-compression of the texture, this one worsens the effect of artefact.
