SyncedWorkflow problem Maya + UE4 + Substance Painter2

micropolius

Hi polycount.

I've been using synced normal map workflow with 3dsmax + Unreal + Substance Painter without problems. 
However..... I am currently adapting to new workflow with Maya + Unreal + Substance Painter.
And this particular part of my mesh is giving me a headache. I tried 
-different frontal max rear, max frontal differences
-average normal checked
 

 I do not know how to resolve this and I am seeking for advice.
Thanks for your time!







Horrible seams and artifacts.

and the same mesh from max works? i'd say the angles are pretty steep for all soft edged and no chamfers applied.

I think it's what @Neox  says. To elaborate on his point. The normal map has to compensate for the difference between the angles in de lowpoly and the high poly. When the difference is too large the normal map will have problem areas like yours. You should put those on a separate smoothing group so there is less difference in angle.

@yannickstoot its a synced (averaged) bake so splitting SGs isn't required. That's why the low poly has a single SG.

OP post up the high/low if you want and I'll take a look.

Thanks for the replies.guys!
@Neox I took your dvice and applied a bevel around the edges. The angle was toooooo extreme for mikktspace to handle it.  Now it works like a charm. Thanks, I appreciate it!

@YannickStoot  Thanks for the feedback but I am using averaged single smoothing group for the normals - synced normal map workflow.

@musashidan Thanks for the feedback, problem resolved.
