Smart Weathering

Smart Weathering is an addon for Blender that provides an easy-to-use node group for realistic weathering effects on materials.

Features

  • Toggle weathering on/off
  • Minimal UI in the 3D View N-panel under the "Weathering" tab for quick access.
  • Edge wear, Ambient Occlusion, Scratches, Fingerprints, and dust (more to come).

Requirements

  • Blender 5.0 or newer.
  • Target object must be a Mesh with an active material. The material must use nodes for the node group insertion to work correctly.

Installation

  1. Download the zip file
  2. In Blender: Edit → Preferences → Add-ons → Install...
  3. Select the .zip you created, enable the add-on, then use the "Weathering" panel in the 3D View N-panel.

Usage

  1. In the 3D View, open the right-hand N-panel and select the Weathering tab.
  2. Select a Mesh object with an active material.
  3. If the material does not use nodes, convert it to node-based by enabling "Use Nodes" on the material.
  4. Click the button ("Enable Weathering")
  5. The add-on creates a group node and connects it to the active material output's Surface socket. If you enabled weathering previously and the node is present but muted, clicking the button will un-mute it.
  6. To disable weathering, click the button again (it toggles the node group's mute state).

Roadmap

Planned improvements and possible future features:

  • Support batch-apply weathering to multiple selected objects.
  • Provide presets (light, medium, heavy weathering) and the ability to save/load custom presets.
  • Add thumbnail preview and inline documentation for node group inputs.
  • Physical Damage, such as dents, and bumps using normals.
  • Surface imperfections like sun fading and oil stains and leakage/streaks.

If you have feature requests or want to help implementing any of the items above, feel free to open an issue or submit a PR.
