Visible seams on model in Toolbag

Valkyrie2271

Hoping someone can help me

When I import my model into Toolbag, the UV seams are visible, even with the default shader on, with no maps plugged in, and are still visible if I plug in an albedo



I sculpted the original mesh in Zbrush and retopologised in Maya 2020. There aren't any visible issues in any other software, just toolbag and I have no idea how to fix it.

Here's the high poly, just in case you need it for reference -

It looks like bad mesh normals/smoothing out of zbrush. I would check if zbrush has settings to soften the mesh normals. Otherwise you may need to import the mesh into a 3D app to soften the normals before bringing it into Toolbag.
