Blender toon shader assistant for Cycles

Cycles toon rendering, without rebuilding every material.

Convert Principled BSDF, MMDShaderDev, and VRM MToon materials to Toon BSDF, then add clean inverted-hull outlines powered by Geometry Nodes.

Designed for character and cel-look workflows

Move from imported materials to Cycles toon shading faster.

Convert materials to Toon BSDF

Replace Principled BSDF with Toon BSDF while preserving available base color, normal connections, texture alpha, and material opacity where supported.

  • Principled BSDF to Toon BSDF
  • MMDShaderDev / mmd_shader conversion
  • VRM MToon conversion

Generate clean Cycles outlines

Build inverted-hull outline objects from the selected model root using Geometry Nodes, excluding hidden meshes and keeping source collections organized.

  • Object-driven outline targets
  • Vertex weight thickness control
  • Refresh and remove outline tools

Tune opacity and smoothness in bulk

Apply opacity and Toon Smooth values across selected objects and child hierarchies, with per-material controls when the active material was converted by CyclesTooner.

  • Batch opacity slider
  • Batch Smooth slider
  • Per-material adjustment
