Why indie game devs use Proofly
Buy only what you need
No need to pay for a $200 sci-fi kit when you need two props. Browse individual assets and small sets — buy exactly the pieces your scene requires.
GLB-first for modern engines
GLB (binary glTF) is the native format for Godot, Three.js, and Unity's glTF importers. Creators on Proofly ship GLB with PBR materials, normal maps, and embedded animations.
FBX for Unreal and Maya
FBX remains the standard for Unreal Engine and Maya workflows. Proofly listings often include both GLB and FBX variants in a single ZIP download.
HiddenMark — know where your asset came from
Every paid download embeds a unique steganographic watermark in the mesh geometry. If a Proofly asset is found in an unauthorized upload elsewhere, the creator can trace the download.
Interactive 3D preview before buying
Proofly's in-browser WebGL viewer lets you orbit, zoom, check wireframe, measure dimensions, and inspect normals before purchasing — no more guessing from screenshots.
Sell your own environment assets
Environment artists and prop creators can publish their work and reach buyers directly. Zero seller commission — creators keep 100% of the listing price.

Frequently asked questions
How much does KitBash3D cost compared to Proofly?
KitBash3D sells themed environment kit collections at $99–399 per bundle (e.g. a sci-fi space station kit, a fantasy castle kit). Each bundle contains dozens of modular pieces. Their subscription plan (KitBash3D+ or Unlimited) costs around $200–499/year for full library access. On Proofly, you buy individual assets or small packs from independent creators — prices typically range from $5–40 per asset. If you only need a handful of specific props, Proofly's per-asset model is significantly cheaper.
Are Proofly assets compatible with Unity and Unreal Engine?
Yes. Proofly supports GLB, FBX, and OBJ formats — the standard formats accepted by Unity (GLB/FBX), Unreal Engine (FBX/OBJ), and Godot (GLB). Many creators include LOD (level-of-detail) variants and pre-configured PBR materials in their packages. You can filter for 'Game Engine' models under the Use Case filter to find assets specifically optimized for real-time engines.
Can I find modular / kitbash-style assets on Proofly?
Yes. Proofly has creators who sell modular environment sets — sci-fi corridors, dungeon tiles, architectural components, and prop collections you can recombine. While Proofly doesn't use the 'kitbash' brand term, the underlying assets (modular pieces in GLB/FBX with consistent scale and snap points) serve the same purpose. You can search by category (Architecture, Sci-Fi, Fantasy, Vehicles, etc.) or use the Game Engine use-case filter to browse relevant assets.
Do KitBash3D files have DRM or restrictions?
KitBash3D assets are licensed for commercial use in rendered images, animations, and games, but the 3D source files cannot be resold as standalone 3D models. Proofly assets come with explicit creator-set licenses (Personal, Commercial, or Extended) shown on every listing. Commercial licenses allow use in games, animations, and product renders. Extended licenses cover asset resale and derivative products. You see the full license terms before purchasing.
Can I sell my own environment and prop assets on Proofly?
Yes. Proofly is a two-sided marketplace — you can buy and sell. Upload GLB, FBX, OBJ, STL, or ZIP packages of 3D environment assets and props. Creators keep 100% of their listing price (buyers pay a flat $1 service fee per order). Every paid download gets HiddenMark watermarking — a unique steganographic code embedded in the mesh — so if your assets are redistributed without permission, you can trace which download was leaked.
What types of game environment assets are on Proofly?
Proofly's game-ready category includes sci-fi interiors, fantasy architecture, nature/terrain props, urban environments, weapons and armor, vehicles, furniture, and decorative objects. Use the 'Game Engine' use-case filter or browse by category (Architecture, Sci-Fi, Fantasy, Vehicles, Characters) to narrow results. You can also filter by format (GLB for web/Unity/Godot, FBX for Unity/Unreal/Maya) and sort by best sellers or top rated.
