Decal machine is an alternative to traditional texturing where we snap a decal as a mesh object on top of our existing mesh. This allows us to use independent texture resolution and more freedom to place decal wherever we want. It is a very fast workflow and the add-on comes with tons of features to manage these decals.
The decals are also compatible with game engines such as Unity or Unreal Engine.
