Kitbashing

Reference entry · last updated August 26, 2026

Kitbashing, also called model bashing, is the practice of building a new scale model, prop, or digital asset out of pieces taken from existing commercial kits rather than sculpting every part from raw material.[1] A modeler with no kit for the subject they want cuts one from several kits instead: a hull from one box, a gun turret from another, greebled surface detail from a third. The term later extended past plastic into digital 3D asset libraries, and looser still, into a metaphor for any creative work assembled from borrowed, credited pieces.

Origin in scale modeling

Wikipedia defines kitbashing as the practice of making a new scale model by taking pieces out of kits, added either to a custom project or to another kit.[1] For hobbyists the appeal is speed: kitbashing a model is faster than scratch-building one from raw styrene, and it is the practical route to modeling a subject, real or imaginary, for which no commercial kit exists. For professional modelmakers building props and miniatures for film and television, the same technique produces detailed concept pieces on a production schedule that scratch-building cannot meet.[1]

Dating the word precisely is harder than defining the practice. The Oxford English Dictionary's earliest citation for "kitbash" is dated 1972, in Railroad Model Craftsman.[2] A 2023 FineScale Modeler search for earlier usage found the word functioning as a title term two to three years before that: "Kit-bashing Business Cars" by John Archer Morton in the February 1969 Model Railroader, and "Kitbashed 60-foot Boxcars" by David W. Messer in the June 1970 issue. Whether either article is the actual point of origin, or an editor's title using a term already circulating among modelers, is not resolved by that search.[3]

Not every modeler adopted the word. Art Curren, a well-known HO-scale modeler at Kalmbach Publishing, avoided it as "too violent and imprecise a term" for what he did, preferring to call the same practice "kit mingling."[3] "Kitbashing" won out as the standard term regardless.[1]

Star Wars and Industrial Light & Magic

Kitbashing existed before Star Wars, but the film is why the term reached people who had never built a model. Wikipedia credits the fine modelwork in Thunderbirds, Star Trek, 2001: A Space Odyssey, and Star Wars Episode IV: A New Hope with bringing kitbashing to a wider public, with many of the spaceship miniatures incorporating parts from tank, speedboat, and car kits.[1]

George Lucas coined a companion term for the surface detail that kitbashed parts produced: "greeble," a word for something that otherwise defies description, according to Frank Burton, a department head on The Empire Strikes Back. Fon Davis, another ILM modelmaker, describes greebles as the tiny tubes and mechanical-looking parts that break up a miniature's surface and make it read as a real, working machine. On the original trilogy, ILM's model shop kept a room stocked on one side with sheet and rod styrene and on the other with commercial kits chosen for their small, plausible-looking mechanical parts, sourced from World War II flak cannons, US Navy battleships, fighter planes, T-34 tanks, and submarines.[4]

One part recurred often enough that ILM modelmaker Adam Savage gave it a name: the "universal greeblie," a small domed piece with four raised pips, sourced from a commercial kit of the Krupp K5 rail cannon, a World War II-era German artillery piece. In Savage's account, "the universal greeblie – the UG – was on, I think, every single Industrial Light and Magic model almost ever."[4]

Kitbashing vs. scratch-building

Scratch-building is the opposite discipline: constructing a model entirely from raw materials, without commercial kit parts. Kitbashing sits between scratch-building and building a kit unmodified out of the box. It draws on manufactured components, the way scratch-building doesn't, but it reassembles and recombines them into something the original kits didn't depict, the way an unmodified build doesn't.[1] The two are not mutually exclusive within one model: a kitbashed hull can carry scratch-built greebles, and vice versa.

Digital and VFX kitbashing

The technique moved from styrene to polygons as visual-effects and game production shifted to computer graphics. Digital kitbashing follows the same three moves as the physical version: an artist selects existing 3D model pieces from a personal or licensed asset library, modifies, scales, or combines them to fit the project's look, and composes the result with attention to visual coherence, rather than modeling every prop, building, or vehicle from a blank scene.[5] The appeal carries over unchanged from the plastic version: it is faster than building every asset from nothing, which matters most in concept and previsualization work where a scene needs to look plausible before it needs to be final.[5] Commercial 3D kit libraries, sold specifically for this purpose, are now a normal part of film and game production pipelines.

Use as a metaphor outside modeling

Outside modeling and VFX, "kitbashing" gets used loosely as a metaphor for creative work built from existing, borrowed pieces rather than invented whole cloth. Writers reuse it as shorthand for combinatorial creativity generally, the way Tiago Forte opens a chapter on remixing one's own notes and work product with the Adam Savage "universal greeblie" story.[6] That usage trades on the modeling image without claiming kitbashing is a formal term of art in those fields. The nearer formal term in software is code reuse: using existing source code, via copy-paste, shared libraries, or frameworks, instead of writing new code. At least one 3D-modeling explainer draws the comparison directly, calling the two "conceptually similar."[7] No source was found establishing "kitbashing" itself as standardized terminology inside software engineering; the connection currently rests on analogy, not shared vocabulary.
