Procedural Cannon Barrel Generator

Create custom 3D cannon barrels in minutes directly inside the Unity Editor. Whether you're building a pirate adventure, naval combat game, medieval battlefield, or historical simulation, this tool lets you design unique cannon barrels without modeling them from scratch.

Using an intuitive 2D profile editor or 3D editor, you can create both the barrel and the trunnions in dedicated editing modes. Simply place and edit profile dots, adjust curves, and instantly generate optimized 3D meshes. Export the result as an FBX or continue refining your design at any time by loading the saved project.

Features

• Create unlimited unique cannon barrel designs.
• Dedicated editing modes for Barrel and Trunnions.
• Intuitive Scene View profile editor.
• Smooth curve editing with adjustable subdivisions.
• Clean, game-ready topology.
• Clean UV mapping optimized for seamless materials.
• Adjustable UV mapping with independent Length, Around, Overall, and Cap controls.
• Multiple material support through automatically generated submeshes.
• Save and load editable .cannonbarrel projects.
• Export generated meshes as binary FBX.
• Includes sample projects demonstrating standard barrels, multiple material setups, and efficient LOD workflows.
• Compatible with Built-in Render Pipeline, URP, and HDRP.
• Works with Unity 2020 through Unity 6.

Fast Iteration

Instead of remodeling every cannon barrel, simply adjust the profile and regenerate the mesh. Change the muzzle, reinforce rings, cascabel, proportions, or trunnions in seconds.

Because projects remain fully editable, creating multiple barrel variants or optimized LOD versions is quick and requires only a few clicks.

Production-Ready Meshes

Every generated mesh features:

• Clean topology suitable for further editing.
• Clean UV mapping designed for seamless materials.
• Standard Unity meshes.
• FBX export for use outside Unity.
• UVs that can be edited or completely replaced in Blender or any other 3D modeling software.

Perfect For

• Naval combat games
• Historical games
• Medieval games
• Strategy games
• RPGs
• Procedural asset pipelines
• Technical artists
• Indie developers

Stop modeling cannon barrels by hand. Design unlimited custom barrels and trunnions directly in Unity and accelerate your workflow.
