ArmorPaint is a free, opensource, stand-alone software in continuous development designed for 3D PBR (Phisically Based Render) high quality texture painting and material creation with an instant feedback of your work.
What is ArmorPaint
The development team of the open-source game engine Armory has created ArmorPaint, an open-source 3d painting tool, capable of generating PBR texture maps for use in other game engines like Unreal Engine and Unity. ArmorPaint was first released in February 2017, and is still a working progress. Last version released is the 0.8dev updated on Jun 16, 2021, which is still to be determined. It is possibile follow every development on GitHub.
With ArmorPaint users are able to paint directly on the 3d model, and receive an instant feedback on the viewport. Thanks to the PBR (Physically Based Rendering) texture paintings, the material applied on the surface of a 3D model looks very realistic in every illumination condition. ArmorPaint is a node-based toolkit, and allow to paint with complex and fully procedural materials. An important feature is the possibility for the user to import 3D assets in OBJ, FBX and, starting with update 0.7, in STL format or as a Blender scene file.

Supports for the use
For those who already know how to use shared nodes, it will be easier to use ArmorPaint. However if someone is interested to approach this tool for the first time, can read a manual on the official website with a brief description on how to use the main tools, materials, brushes, layers, viewport, baking, workspaces, preferences and plugins.
