I need to automatically paint a line on edges(corners that covers normals too) where normals have an angle more than %myValue%. So before I never tried something like that in Blender. Can you guys tell me how to do it? First I need to set up an angle like when you use "Smart UV project" you set up an angle for Unwrap so there is a function to detect that angles. Do i need to write a script or Blender has a built-in function or plugin already?
p.s. generally this question comes to the "Texture Paint" mode where I want to automate the process.
