Well, you first need to learn the basics of the texturing workflows, I can't give you a full size tutorial on everything here.

You have 5 different TextureSets in Painter for that single piece of clothing, which probably doesn't make sense, unless you need extremely high texel density/ texture resolution. You probably only want a single TextureSet for that piece shown on your screenshot, or at least import it so you are able to paint across UDIM tiles. Right now, you would have to texture each TextureSet separately, without the possibility to paint across the borders of each set, which probably isn't what you want.

If you have no idea what I am talking about, and don't know what UDIMs are and even what a UV layout is, you need to go way back before even importing your object into Painter, because setting up the object correctly before importing it is essential.

To start, post your UV layout as it is right now in Substance Painter. Go to the '2D only' viewport, activate wireframe display, take a screenshot, and post it here.

Or, if you want/ can, post the OBJ file so I can take a look at it directly.

You need to either mask off the faces and use a separate smart material with the directional effects rotated 90°, or adjust the UVs (UV island circled in red separated and rotated 90°).

Is there a reason why you created multiple TextureSets for that object?

Post a screenshot of your UV layout please.

It is most likely about the baked mesh maps. Re-bake all the maps, and drag-and-drop the maps into all slots (fill layers, masks) where they might be used. They will not be replaced automatically.

Can you share the highres + lowres meshes?

You need to increase the spacing of the UVs, there is 0 distance between islands. Also add margin of a couple of pixels (so UVs are not located directly on the border of the UV space).

You probably also want to add a bevel to the additional indentations you have in the highres model, those 90 degree sharp extrusions will not bake well. Also, remove the ngons (polygons with more than 4 sides).

Post your system specs please. Might be insufficient VRAM.

Make sure to set the correct normal map format for the target application in the Painter project (Edit -> Project Configuration -> Normal map format).

You can't apply a second fill effect to the mask, and then mask that fill effect using a paint effect in that same effect stack.

What you need to do is apply the first fill effect to the mask of a fill layer, then put that fill effect into a group, apply the second fill effect to the mask of the group, and then create a paint effect in the effect stack of that group to paint away the mask.

If thats not what you want, I'm lost.

See screenshot.

Create separate UV islands for each branch/ root, and align all UV islands vertically or horizontally. Ideally, use the 'rectangularize' feature in your UV layout app to morph each island into a rectangular shape, the bark will then just follow the direction of each branch automatically if you set the smart material to utlize the UV layout (not triplanar).

You can use a single smart material for the enire tree this way. Then e.g. use the clone brush to hide the seams.

What about the angled result? Is there a way to make it bake directly front view with no angle?

Not in Painter unfortunately. You need to bake the normal map in Designer or in Marmoset Toolbag and use the 'skew correction' feature.

Can you share the body of the guitar (high + low, or maybe cut off the part with the artifact on it)?

The error message tells you exactly what the problem is, it even tells you the problematic tile (2-1). Each UV island must be within one specific UV tile, it cannot cross from one tile into the next.

Locate the UV island that intersects with the border of the tile, remove the intersection (move it away from the border), then re-import into Painter.
