What are free tools for texture armature 3D models?

Free tools for texturing and rigging (armature) 3D models include Blender (all-in-one), GIMP (2D texture edits), and Krita (brush-based painting). Blender is open-source and covers UV unwrapping, texture painting, armature (skeleton) creation, and weight painting—ideal for end-to-end work. GIMP edits 2D textures (like diffuse or normal maps) to apply to rigged models. Krita uses brush-focused tools for detailed hand-painted textures before rigging. Beginners can start with Blender’s built-in tutorials, which guide you through texturing and basic armature setup without extra software.
