Viktor's Mossifier is a procedural geometry nodes system that generates detailed moss across 3D surfaces. The setup combines instanced moss strand meshes with an underlying moss shader utilizing 4K textures, ensuring the resulting geometry holds up in both distant and close-up renders. Users can customize growth patterns, moss colors, and strand shapes directly through the modifier panel.

Applying the tool requires appending the setup to a scene, adding the geometry nodes modifier to the target object, and connecting the provided shader function to the object's material. A workaround is provided for preserving attributes and normals when realizing instances.
