Proper Workflow from Marmoset 3 Bake to UE4

Hey guys,
I am doing a few bakes from Marmoset 3 and taking them in to UE4 but
not matter what I do(flipping channels, properly setting up textures and materials in UE4, proper file export), I cant get the tangent space to look right. I tried rendering object space and converting that with Handplane but it seems like Handplane doesn't really understand the object space settings that Marmoset bakes out.
I tried pretty much every conceivable settings in Handplane as well(Target tangent, swizzing channels etc).

    I believe TB3 uses Maya style object space maps, there is probably a setting for that.

    Saying that, unreal uses Mikktspace as far as I know, so you should set your tangent space to XN/Mikkt. Go to the lowpoly object properties and change it to Mikkt, you'll have to do this for every lowpoly object, however, you can go to edit-> preferences and set a default tangent space which will apply to newly imported meshes.

    You'll want to click flip Y as well in the bake settings. Unreal uses Max handness rather than Maya handness with is the default in TB3.
