Info:
DECALmachine is a blender addon, which through mesh Decals, allows for surface detailing in a very non-committal, non-destructive, UV-less way. And as such, it represents an alternative approach to hard surface texturing.
Decals can be projected, sliced, material matched, and of course easily created.

easily select decals by parent object or by type
automatic material matching, parenting, normal transfer and collection creation
unlimited decal libraries + flexible asset loader layout
