I have a procedural material on the model, something like chipboard for furniture. I bake textures with both standard blender tools and texttools, but the normal map is somehow wrong.
I notice the problem when exporting the model to gltf and then viewing it in modelviewer
Here is a model for reference. I hope you can tell me how to solve this problem.
tumbabrake.blend (1.1 MB)
I rendered another model using standard baking methods + textools. The result was pretty good. So, most likely, the furniture model has incorrect normals, or I baked everything incorrectly in that case.
God, if you only knew how long I’ve been suffering… 
Could you attach a copy of the .blend after the baking is done? From the screenshot your baked material graph looks compatible for export to me, but might help to inspect the .blend.
Victory!
The problem was as follows: 1. I incorrectly set up the roughness via normal on the procedural material, and for some reason I thought that when baking the textures should magically become many times better (?!). 2. I sometimes baked the components of the material incorrectly, which is why I got an unacceptable result every time.
My wishes to those reading this question and answers: try to understand the baking process itself more deeply, double-check everything a bunch of times, and don’t be afraid to experiment! Peace
