Grow animated tentacles from a base mesh using native Blender Geometry Nodes. Shape a displaced creature head, tune its tentacle population and add noise-driven motion without building a separate tentacle rig.

Controls

• Head subdivision, displacement scale, detail and strength.
• Tentacle spawn height, density and spacing.
• Minimum and maximum length, width, curve resolution and mesh resolution.
• Chaos/stretch, noise scale and motion speed.
• Separate head, tentacle and tip materials, plus the supplied viewport fog control.

Included file

The full Standard generator: 3DT Tentacle Creature Geometry Node Resource Pack.blend. This is the editable generator file.

Getting started

Open the file, save a working copy and select the supplied generator object. Adjust its Geometry Nodes modifier, starting with moderate subdivision and tentacle resolution. Balance density and detail for the shot you are building.

Compatibility

The inspected source was saved in Blender 4.4 and opened successfully in Blender 5.1.2, using Cycles. No add-on installation is required. Native node controls run in Blender; prepare and export converted geometry separately for a game engine.

Choose the appropriate Cubebrush licence for your intended use.
