KitBash3D is the most recognized name in modular 3D asset kits for game development and VFX. But its curated catalogue, high prices ($99–$499 per kit), and limited genre coverage send many buyers and creators to alternatives. This guide covers what KitBash3D does well, where it falls short, and the best platforms for both buying modular 3D packs and selling your own.

KitBash3D (kitbash3d.com) is a marketplace for modular 3D asset kits — curated collections of props, building pieces, and structural elements designed to be assembled into environments quickly. The name comes from "kitbashing," a physical model-making technique where artists combine parts from different model kits to build new objects.
KB3D's assets appear in major film productions and AAA games. Their sci-fi kits in particular became industry standards for concept art, previs, and final environments. Kits typically include hundreds of modular pieces — walls, floors, props, structural elements — that snap together to build scenes without starting from scratch.
KitBash3D quick stats
$99–$499 per kit is a significant investment for indie developers and students. Many of the same use cases — assembling a sci-fi corridor, building a dungeon — can be covered with individual modular assets from independent creators for $15–$50 total. Buyers with tight budgets need alternatives.
KB3D excels at sci-fi, cyberpunk, and high fantasy. Underrepresented: historical (medieval Japan, ancient Rome), stylised/cartoon aesthetics, horror/dark, low-poly, underwater, organic jungle, and Eastern architecture. Indie developers in these genres find richer catalogues on broader marketplaces.
KitBash3D is a closed production house, not a creator marketplace. If you build your own modular asset kits, you cannot list them on KB3D. Creators building kitbash-style packs need a third-party platform that supports multi-file ZIP bundles and gives buyers a 3D viewer to inspect pieces before buying.
KB3D's subscription gives access to rotating free kits but locks you in monthly. Buyers who need one specific kit type prefer a one-time purchase. Alternatives let you buy exactly the pack you need without a subscription commitment.
| Platform | Creator Sales? | Commission | 3D Viewer | Best For |
|---|---|---|---|---|
| KitBash3D | ✗ Closed | N/A | ✓ Good | Buying premium kits |
| Proofly | ✓ Open | 0% (buyer pays $1) | ✓ GLB/FBX viewer | Creator-first, max revenue |
| TurboSquid | ✓ Open | 40–60% | ✓ Sketchfab embed | High traffic |
| CGTrader | ✓ Open | 30–50% | ✓ Viewer | European buyers |
| Fab (Epic) | ✓ Open | 12–30% | ✓ UE5 viewer | Unreal Engine devs |
| ArtStation | ✓ Open | ~35% | ✗ Images only | Portfolio + discovery |
| Gumroad | ✓ Open | ~10% + fees | ✗ No viewer | Own audience |
| Sketchfab | ✓ Open | 30% | ✓ Best viewer | Showcase + discovery |
Proofly, CGTrader, TurboSquid — independent creators sell modular packs for $15–$80 that cover the same use cases as $200–$499 KB3D kits. You get a smaller piece count but often more specific genre coverage. Search for "modular kit," "environment pack," or the specific genre + "tileset." Proofly's 3D viewer lets you inspect geometry before buying.
Fab (Epic's marketplace) — the merger of the former Unreal Engine Marketplace, ArtStation Marketplace, Sketchfab Store, and Quixel. Large catalogue with native UE5 integration. Prices are comparable to KB3D for premium packs, but the indie creator tier has far cheaper options. Filter by "Environments" → "Modular."
Proofly, CGTrader, Fab — independent creator marketplaces cover genres KB3D ignores. Historical Japanese architecture, stylised cartoon props, underwater environments, low-poly mobile-friendly packs — search across these three platforms for the broadest coverage.
If you create modular asset packs and want to sell them, KitBash3D is not an option — it's a closed production studio. Here's where to list your kits:
0% commission — you keep 100% of every sale (buyers pay a flat $1 service fee). In-browser GLB/FBX viewer so buyers can inspect your kit pieces before purchasing. HiddenMark piracy tracing embeds a per-buyer watermark in every file sold — if your kit appears on a piracy site, you can identify the source.
Epic's unified marketplace has the largest audience of Unreal Engine developers. Lower commission than TurboSquid (12–30%), native UE5 content pack support, and the built-in audience of developers already browsing for assets. Requires a more formal content submission process.
~10% + payment fees. If you have a Twitter/X, Instagram, or YouTube following in game dev or 3D art, Gumroad converts well for fans who already know your work. No built-in discovery — you bring all the traffic.
40–60% commission at TurboSquid, 30–50% at CGTrader — but they have large existing buyer bases. Use these for discoverability while listing the same kit on Proofly at a price that nets you the same after commission (or more).

| Theme | Primary Buyers | Demand |
|---|---|---|
| Sci-Fi Interior (corridors, consoles) | Space game devs, sci-fi film previs | ★★★★★ |
| Fantasy Castle / Ruins | RPG devs, TTRPG virtual tabletop | ★★★★★ |
| Dungeon / Underground | Roguelike, action RPG devs | ★★★★☆ |
| Industrial / Post-Apocalyptic | Horror, survival game devs | ★★★★☆ |
| Low-Poly Stylised (any genre) | Indie, mobile, casual devs | ★★★★☆ |
| Medieval European (village, town) | RPG, strategy devs | ★★★★☆ |
| Cyberpunk Urban Street | Cyberpunk game devs, VFX | ★★★☆☆ |
| East Asian Architecture | Action, martial arts, historical game devs | ★★★★☆ (underserved) |
Opportunity gap: KitBash3D dominates sci-fi and Western fantasy. East Asian architecture, stylised low-poly genres, underwater/deep-sea, and horror organic environments are all underrepresented at the premium tier — independent creators filling these niches face less direct competition.
| Pack Size | Piece Count | Price Range | Positioning |

KitBash3D is a US-based 3D asset marketplace specializing in modular prop and building kits for game development, VFX, and cinematic production. It launched in 2016 and is best known for its high-end sci-fi, fantasy, and urban environment kits used in films and AAA game productions. Kits are sold as curated packs of modular pieces that artists use to quickly assemble environments — 'kitbashing' rather than modeling everything from scratch. Prices are typically $99–$499 per kit.
Several reasons: (1) Price — KitBash3D kits cost $99–$499, while comparable assets from independent creators on other marketplaces are available for $15–$80. (2) Niche — KB3D focuses on sci-fi, fantasy, and urban environments; other genres (stylised, low-poly, horror, organic, creature-heavy) are underrepresented. (3) Creator economics — creators building their own modular kit packs often prefer platforms with lower commission rates. (4) Variety — KitBash3D has a relatively curated catalogue; for genre variety (historical, Eastern, underwater, etc.) you need broader marketplaces.
Proofly (0% commission — you keep 100% of the sale price; buyers pay a flat $1 service fee), TurboSquid (40–60% commission), CGTrader (30–50%), Fab/Epic Games Store (12–30%), ArtStation (35%), and Gumroad (~10% + fees if you bring your own traffic). For modular packs specifically, Proofly and Gumroad let you bundle dozens of assets in a ZIP with your own folder structure and README, which kitbash buyers expect. The GLB preview viewer on Proofly lets buyers inspect individual pieces before buying.
FBX (primary — Unity, Unreal, Maya, 3ds Max, Cinema 4D all import it), GLB (Godot 4 native, web viewer, AR), OBJ (SketchUp, fallback). Include both modular individual pieces as separate files AND a pre-assembled scene showcase. PBR textures at 4K: Albedo, Normal, Roughness/Metallic, AO. Game-ready: ORM packing (Occlusion in R, Roughness in G, Metallic in B). Include a README with poly counts per piece, UV layout info, and what engines were tested. Buyers who can inspect the mesh in a 3D viewer before buying convert far better than those limited to screenshots.
Sci-fi props and structures (interior corridors, consoles, machinery) have the highest consistent demand — used in space shooters, cyberpunk games, and sci-fi film. Fantasy environments (castle walls, ruins, forest props) are perennial RPG staples. Urban environments (streets, building facades, signage) for open-world and city-builder games. Dungeon/cavern modular sets for roguelikes and RPGs. Industrial environments (pipes, tanks, catwalks) for horror and survival games. Stylised low-poly environment kits have a large indie game dev audience. The gap KitBash3D leaves unfilled: historical (medieval Europe, feudal Japan, ancient Egypt), organic/jungle, and stylised-anime themes.
0% commission. ZIP upload with any folder structure. In-browser GLB viewer so buyers inspect your kit before buying. HiddenMark piracy tracing on every purchase.
