Shapespark Texture issues

I have been having issues with textures after baking the entire scene.
I have a base material where I have used material picker to pick other materials.
The base material appears okay after baking but the other material has visible edges around the texture and I cannot seem to find my way around it. Attaching a picture of the texture here.
I would really appreciate someone can offer a solution to this problem.

Could you send me link to the scene? It can be via private message if the scene is not public. I will take a look at it.
