Procedural Circular Graining - Quick Start Guide

1. Installation & Setup

• Install the .zip file like any standard Blender add-on (Edit > Preferences > Add-ons > Install).

• Check the box to enable it.

• Open the Shader Editor and press 'N' to open the right-side N-panel. You will find the add-on tab there.

1. Two Workflows Available From the N-panel, you can append two different node groups to your material:

Method A: OSL Node Group (Cycles Only)

• This node is 100% plug-and-play.

• IMPORTANT: You must enable "Open Shading Language" in Blender's Render Properties (under Cycles) for the node to compile and work.

Method B: Texture Baking Node Group (Cycles & EEVEE)

• This method generates physical texture maps, making it compatible with EEVEE and avoiding OSL limitations.

• Adjust your graining parameters directly from the N-panel interface.

• Click "Generate" to calculate your Perlage textures. The node will automatically update.

• Note: If your 3D Viewport is currently set to "Rendered" mode, you need to quickly toggle out to "Solid" and then return to "Rendered" to force Blender to refresh the textures visually.
