I'm trying to bake my high poly from zbrush on to my low poly but these errors keep showing up and I'm not really sure why, some advice would be great. Never encountered them and my mesh from maya has no errors or ngons it seems.

This happened to me after exporting from Maya. I had to go back and do this: Mesh Display>Unlock Normals>Mesh Display>Conform. I think that some of the faces of the mesh were flipped.

I've found success with using the ZRemesher tool in fixing this issue, similarly to what Cyril Dellenbach recommended below. You can find it in Tool>Geometry>ZRemesher. I set mine to "Same" so that my polygon resolution remained about the same, and so it just shuffled around the polygons.

I've never seen that message, but take a look at this thread in the old Substance forum where someone had the same issue due to stray verts.

Hello Dave,
It is now 2022 . that answer in the thread is not there, from the link you sent. I have the same problem. Can;t export normals because triangles in mesh too small. I don.t want to waste time painting if I can't bring in the normals. I wonder if you will see this...

I can't see that thread now. However if I remember correctly, the problem was due to stray single vertices in the mesh. It was resolved by cleaning up teh mesh and removing such single vertices.
