Build sandbag walls, fighting positions, machine gun nests and bunkers in seconds.
Sandbag Barricade Generator is a Geometry Nodes tool for Blender that stacks sandbags along any curve. Bags are staggered like brickwork, follow corners, and can be damaged, tapered or ramped with a few sliders. For Unreal Engine and other engines, the pack also ships 5 pre-built walls and 8 single bag meshes as FBX, so you can use it without opening Blender.
Generator featuresWorks on any curve: Bezier, NURBS, Poly, open or closed loops, several splines per object
Rows, wall thickness, brick-style stagger, settle (bags sink into each other)
Ramped ends, pyramid / bunker profile, leaning parapet
Battle damage: breaches that eat into the wall from the top (no floating bags), fallen bags on the ground
Seed, position, rotation and scale randomness
Per-bag colour variation (also exported as vertex colour)
Swap in your own bag meshes
