Weird edges in Substance Mesh...Please help

ivanlyw

Hi there, I am currently trying to make an asset for a VR game in Unity for a school assignment. I am currently facing a problem with a bake from substance.I am still new to substance and I am getting these weird edges which looks bad.. I need the mesh to be low poly so i cant smooth the mesh too much to get better bakes. I have seen meshes where its super low poly but the bakes turned out really good. I turned up the subsampling to 4x4 but it still looks the same.this is my Zbrush mesh.this is my maya mesh.this is the problem i am facing.. 
 these are the settings that i have exported(lowpoly)

My question is, is it possible to keep my current mesh that low poly to bake from the high poly or do i have to smooth my mesh before baking?

Your UVs aren't straight so you're seeing aliasing artefacts and inconsistent texel density at seams.

Make the uvs good and this will go away

Using dilation should fix this.
