[Substance Painter] Weird edges at baking process

Vargo

Hello. I started to burn mesh maps in substance painter and noticed that the edges on the low poly model did not look right. What could it be caused by? Did I do something wrong with the model itself or is it a matter of bake?

straighten UVs,  increase padding to bigger number, enable antialiasing

also if you're going to put the camera that close, you probably need more geometry

Thanks for the reply. Unfortunately, even after applying these fixes, these artifacts still appear. I was wondering if it was not the fault of badly weighted normals or sharp edges. Could this be the cause?

You probably collected a bunch of possible issues. 
- non straight uvs
emphasising
- too low resolution
emphasising
- sharp edges issues 

As usual with these question: post your UVs, the low (with shading visible), the high.

Thanks for replay!
This is my UV layout:

Here is LP with wireframe and without:


And HP:

the UVs for the bits with the artefacts are not straight . you also need to split and pad at hard edges

there's not a lot you can do about straightening the circular bits but antialiasing during the bake is usually sufficient
if not try baking at double size and downsampling

Ok, thanks for the answer! I will try to repair this texture
