Sorry if this has been posted already, but I for the life of me can't find an answer to my problem. My normal maps keeps baking out with really odd artifacts, and no matter what I try I can't get rid of them. This is part of a larger model so the UVs are rather small, and I know you need more resolution for non straight lines, could that be the problem?

Low poly and High poly meshes:
UPDATE: Turns out it is indeed the size of the uv layout, so looks like I either need to increase the size of the uv elements, or I also found I get decent results if I bake out 8k maps. If anyone has any other solutions though would love to hear them.
