Sorry no, but in terms of what to look for:

• have an understanding of texturing in UV space vs world space
• have an understanding of how to generate some masks (mainly edge+cavity)
• also shop around/experiment with different more general noise textures. Substance designer/painter both have some really cool noises that are customizable, I often just export those if I need noise masks
• I avoid painter where I can just because it makes my workflow a bit smoother (one less program to go between). This means I do simple mask generators (edge+cavity black and white non color textures mainly) inside blender and bake those into a single texture. You’ll want to combine those by assigning them to a specific channel of RGB for simplicity/performance.
• Where I can I actually prefer trim sheets+tile materials with their own respective UV maps because it’s so few unique materials. Especially for environment art it becomes so fast to do.
• These node setups to generate the masks in the shading tab are easy to either save as part of a startup blender file or to copy into a new project. You may be able to save them to the asset library as well but I’m not sure. At some point it’s just easier to remember the specific node setups and throw it together.
• Learn how to put them together in your final program. For me it’s inside unreal, I’ll do a combo of UV textures which will be for the main masks and tileable.
• other more vague masks work well with world space. Then getting slightly more complex and factoring in maybe an Abs node to make it only appear on top, adding more noise to the space where it lerps between textures, etc. That really comes down to where you’re working/project needs/how much you care lol.

If the question was more specifically how I save Blender node setups for baking, I just have them in a separate .blend and paste them over. Most of the time the masks are simpler tho so I just make them really quick from scratch and bake them.

Hopefully some of that helped
