Zbrush scaling, baking normal maps

[supremeloser123]

So I just recently finished my sculpt in zbrush, and zremeshed it into a low poly thing, and got it down to specs. Now i need to bake the normals, but it wasn't working. I figured out the reason was that because i had hand unwrapped it in blender, the scaling between the 2 objects were off and I was getting errors in substance painter. I did a xnormal back and it confirmed it because all the map showed was a little nub in corner. So now i need a solution as to how i get these 2 objects to match scaling. I dont think i can do it in blender, is there a method for this in zbrush or substance?

You probably need to setup blender to work in meters or the us equivalent

1.Make a new project in zbrush

2.check your import/export settings (bottom right corner of zbrush)

3.import back high/low models into zbrush

4.scale/move high or low poly model manually (without offseting it from the middle)

Sometimes scale gets messed in zbrush and only manual way may fix it, usually it's because the starting model you use/import
