Baking artifacts on flat surfaces

Artmonso

Hello guys I am experiencing some artifacts when baking. The fact is that I tried to optimize those flat areas removing unnecessary edges and making them converge into the same spot. Not always, but in some areas this things appears. Any ideas? Thanks!

Looks like you have hard edges and/or unwelded vertices.

yeah i would assume the same.

these artifacts here look like your lowpoly has too much shading and there isnt enough texture resolution for the normalmap to compensate
