Columnar Cactus Generator

Create realistic columnar cacti in just a few clicks with this procedural Geometry Nodes asset for Blender.

The Columnar Cactus Generator is created entirely with Geometry Nodes and works seamlessly in both Cycles and Eevee. The preview animation was rendered in Cycles.

Designed for the LTS releases of Blender 4.2, 4.5, and 5.2, the generator lets you create the most iconic columnar cactus species—including Saguaro, Organ Pipe, and San Pedro—using a single intuitive modifier.

Whether you need a single hero cactus, a natural-looking cluster, or an entire desert landscape, the generator provides a fast, non-destructive workflow with extensive artistic control.

Mesh Mode & Curve Mode

The generator supports two powerful workflows, easily switched with the Use Input Curve toggle.

Mesh Mode

Apply the asset to any mesh object to generate realistic procedural cacti. Perfect for creating individual plants, cactus clusters, or large desert environments.

Curve Mode

Apply the asset to a curve and use Blender's Draw tool as a creative brush. Sketch curves directly in the viewport to create single cacti, cactus formations, flowing patterns, decorative designs, or completely original cactus-inspired creations—all procedurally generated from your strokes.

Key Features

• Generate realistic Saguaro, Organ Pipe, and San Pedro cacti.
• Instantly switch between Mesh Mode and Curve Mode using the Use Input Curve toggle.
• Create a single cactus, natural cactus clusters, or vast desert landscapes.
• Draw unique cactus arrangements directly in the viewport with Blender's Draw tool.
• Built-in Snap to Environment option to automatically place cacti on any surface.
• Select the target object with the Environment picker.
• Optional Realize Instances output for export workflows, while the default instanced mode provides maximum viewport performance.
• Independent controls for the main trunk and branches, including scale, rotation, and tilt.
• Fine control over the stem profile, including rib count, rib depth, rib sharpness, and other structural details.
• Adjust spine length, thickness, density, and overall surface coverage.
• Create natural-looking cactus groups with adjustable count and distribution radius.
• Built-in randomization for size and rotation, ensuring every cactus looks unique.
• The same clustering and randomization tools also work with custom cactus designs created in Curve Mode.
• Fully procedural and non-destructive Geometry Nodes workflow.

Whether you're creating realistic desert environments, stylized scenes, or artistic cactus illustrations, the Columnar Cactus Generator provides a flexible workflow that combines speed, procedural control, and creative freedom.
