EXPORTING from MAYA to SUBSTANCE PAINTER

neverland

Hi guyz 

I would like to ask you something regarding substance since I am quite new to it...
when I export my asset from maya is there a particular workflow that you recommend ?
Like I have heard arund that the model is supposed to be smoothed prior exporting the file to substance..
smoothed I mean :
modify>convert>smooth mesh preview to polys

I really have quite a bit of confusion regarding this exporting thing so if you have time could you please tell me your workflow to do it? it would be much appreciated.
Thank you so much 
Cheers

Export in centimetres and either make sure tangents and binormals are exported or triangulate the mesh.

Also 

Set your low res normals in maya and disable average normals in your painter bakes.
