Otoy’s Lino Grandi has released Octane Edge Tools, a no-cost Blender add-on targeting users of OctaneRender. The toolkit brings a streamlined, geometry-based workflow for creating outline renders within Blender, relying on Geometry Nodes and vertex groups to generate mesh-based edges.

Described by Grandi as “clean, fast, and completely integrated into your workflow”, Octane Edge Tools is pitched as a solution for artists seeking quick, customizable anime-style or technical outline renders—no scripting or complicated shader hacks required.

How Does It Work?

The add-on leverages Blender’s Geometry Nodes system to generate mesh outlines directly on your 3D model. These edges are then rendered using OctaneRender’s Toon Material and Toon Light features, producing classic NPR (non-photorealistic rendering) results.

Artists can set outline thickness globally, per object, or even assign different values to specific model parts. Control extends down to selecting whether to render all edge loops, specific loops, or even individual edges. The result: both technical documentation–style pure outlines and stylized, toon-shaded anime looks are a few clicks away.

The toolkit is intended for use with OctaneRender, which remains free for Blender users running a single GPU. According to Grandi, the process is “quick” and “intuitive”, as demonstrated in a workflow video. Grandi, currently Product Manager for Octane for Blender at Otoy, is no stranger to stylized rendering. His ArtStation gallery showcases anime-inspired animation.

Is Blender Itself Getting This? Not Quite Yet

Blender proper is also working on its own non-photorealistic rendering (NPR) tech, collaborating with DillonGoo Studios on an experimental NPR branch. However, this branch is not scheduled for mainline Blender integration until after version 5.0 is released, which the Blender Foundation says will arrive in November. Until then, add-ons like Octane Edge Tools fill the gap for NPR stylists.

Download and System Requirements

Octane Edge Tools requires Blender 4.4.3 or later, and OctaneRender 2025.2 or newer. The add-on is available as a free download. Full documentation is online for artists who want to explore its feature set before installing. Download here and see the Octane Edge Tools Documentation
