First Steps in Substance Painter - need help

Question

hi guys, I'm new to substance painter. I still have my problems and a few questions. maybe someone can help me? would be very grateful.
I built a few simple objects to practice:

I work with blender and have used some modifiers. boolean, sub div, bevel etc.

I had unwrapped these objects. but then in substance painter i do not get good results of the baked maps.

- I found out that I have to apply all modifiers. only then can I unwrap. Is that right?

(boolean creates new faces, which are then unexpectedly placed on top at the uv map?)

- I have unwrapped this part. i made a seam on this side (red one).
why does the AO map and also (as seen here) the curvature map make a edge there? can i avoid it?

I am grateful for any help!

bye

You don't necessarily need to apply all modifiers, but Boolean should indeed be applied before unwrappin.

For the edges and seam issue - can you post the mesh ?

If you unwrap using Auto in Painter then you will need to export the mesh and import it to Blender. Otherwise you are using one UV unwrap from Painter to map out the textures and a different unwrap, from Blender to apply them in Blender.
