  that doesnt look like a baking error, but a "simple" projecttion error? what does the baked mesh look like without the texture applied?

  a quick hacky fix would be masking the edges and highlighting them to blend the top end the side together a bit more.

  okay that is indeed a normal issue. could still come from the texture if the woodgrain is projected.

  
  

  texeldensity might be too low or too varying across pieces for the level of detail

  was the mesh baked in substance painter or outside of it?

  might be a tangentspace issue, could be a triangulation issue, but doesnt look like one at first glance.

  Hi! Props for attaching files :-B
  
  
  
  Taking a look at the lowpoly, I'd say with beveled edges and the resulting mesh shading, hard edges become redundant. While hard edges need UV splits (when baking a normal map), not every edge along a UV split needs to be shaded hard. I would use use hard edges deliberately in places where it meaningfully removes gradients from mesh shading, like steep angles.
  
  Then, I recommend straightening the UV islands to not have aliasing artifacts along seams. When not using hard edges, you can have fewer seams in areas where they're less noticeable.
  
  I also think that texel density is too low here. To address that, you could
  A - increase texture resolution
  B - texture by mapping UVs to an trim atlas
  C -  assemble the crate from a couple detailed board modules
   or perhaps it's a combination of those options. And likely there's more
  
  Keep it up

  i tried baking in both painter and marmoset

  Thank you, @fabi_g! I still have a lot to learn, but I really appreciate your help and the insights you shared. I’ll do my best to apply what you and others have suggested. Thanks again!
