DECALmachine is a blender addon, which through mesh Decals, allows for surface detailing in a very non-committal, non-destructive, UV-less way. As such it represents an alternative approach to hard surface texturing.
In addition DECALmachine has deep Trim Sheet support, and supports Atlasing, as well as Baking to facilitate exporting to game engines like Unity, Unreal Engine etc.

Decals can be projected, sliced, created from grease pencil or edges. They can be material matched, and you can easily create your own.
Trims can be easily placed, cut, manipulated or removed – all directly in the 3D view.

DECALmachine 2.13 works with Blender 4.2 to 4.3 !

raise minimum version to 4.2

supplied decals are now ready to be used in 4.2 without an asset update
in 4.3 require asset update due to new Diffuse Roughness parameter in Principled BSDF shader
Pie menu

add Select tool
previously only keymapped to double LMB
Select Decal(s) tool

with decal parent(s) selected support filtering by decal type in redo panel
Simple, Subset, Panel, Info or any combination
Adjust tool

support adjusting Info Decal alpha using ‘A’ key
limit to a minimum of 0.1
support toggling flat/smooth shading using F key
when flat shaded disable normal transfer mod too
expose and support toggling normal transfer mod only when decal is smooth shaded
only expose adjustment modes and mode hints, that are actually available based on the selected decals
indicate if glossy rays, parallax, normal transfer of invert is used by the selection of decals
support “Mixed” selections
when toggling mixed selections, sync the toggled prop
always ensure a displace and normal transfer mod is present
Project tool

support Shrinkwrapping (modifier level shrinkrawp) of Panel Decals (on MESH objects)
useful to better fit underlying curved geo, while requiring less height to distance the decal
support projecting on non-mesh objects too: CURVE, SURFACE and META
ensure normal transfer mod is disabled when projecting on flat shaded objects
improve user feedback, should projecting fail
Slice, EPanel, GPanel tools

support Panel Decal creation on non-mesh objects too: CURVE, SURFACE and META
avoid always smooth shading panel decal, make it dependent on decal target/parent object
ensure normal transfer mod is disabled when creating panel decal on flat shaded objects, or on non-mesh objects
