Bad Bakes in Substance Painter

xMIDIMA

Hello
So, I've trying to bake this piece but I keep getting jagged lines, instead of straight lines and I can't figure out the reason.
I've seen people adding support loops to the mesh and that worked for me in other regions where this problem was also happening, but not on this part of the model.
I'm attaching 3 images to this post, the scene, UVs and the bake with only the normal map baked.
Pay no mind to the unused space in the UVs, I'm just testing for now.
Any help would be greatly appreciated

Rotate the camera until the waviness disappears.. Tadaaaaaaaa!!

w-what

Because there is one viewing angle from where every wavy line looks perfectly right.
It's a joke directly related to what Obscura posted.

Oh, I though I was missing something obvious ahah.
Even after adjusting my topology to have more geo thus more supporting edges than what I would like my lowpoly to have, these lines are still wavy.
What I don't understand is that I fixed all the other spots where this was happening with this technic, but I can't fix the wavy lines on this specific area.
Please let me know if you have any other idea why this is happening

Maybe you should post a image of your low poly and high poly overlapping. Though to be honest it looks exactly like the thing Earthquake explained in the post Obscura posted, meaning your low poly isn't round enough to match the high poly.

Hi! Yeah, I just fixed it and that was the problem, I needed more vertical geometry
Thank you

Hi again.
So, I added loops, fixed some of the topo and mapped everything again. The result is still the same. I even added way more geo than what I would like my lowpoly to have. Do you have any idea what else may be causing this? I don't have 90º edges or long sections without support loops, so I don't know why this is happening.

I see you haven't changed all spots causing the issue and you say the issue is still there.. well


You try to bake a curved surface (highpoly segment) onto a flat one (one of the lowpoly-polygones). From the direction you baked (the lowpoly's surface normal direction) these waves are not visible. But when you rotate the camera to look from a different angle you see them. 

Why?

If you answer this I tell you how to fix your issue (if you still need help then)

Because the normals of the highpoly are pointing in a different direction than the lowpoly normals, I guess?
Sorry for the late response, I managed to solve the problem by adding more vertical support loops (more curvature) which is pretty much what you said the problem was Thank you
