The 30% Problem: What Unity's Commission Actually Costs You
Unity Asset Store operates on a 70/30 revenue split that has been in place since the store launched. Every time someone buys your asset, Unity takes 30% — automatically, with no option to negotiate regardless of your sales volume or tenure on the platform.
The impact compounds at scale. A creator selling $2,000/month in assets pays Unity $600/month — $7,200 per year — just for the privilege of listing on the platform. A mid-tier creator at $5,000/month loses $18,000 per year to the revenue split.
Revenue comparison: $20 asset × 200 sales/month
Proofly solves this with a different fee structure: the seller pays 0%. Instead, the buyer pays a flat ~$1 service fee added to the checkout. For the buyer, it's a small, transparent cost. For the creator, every dollar of their listed price comes through to their account.
Ecosystem Lock-In: Unity Asset Store Buyers vs Everyone Else
Unity Asset Store is purpose-built for one audience: Unity game developers. Assets are delivered as .unitypackage files that import directly into Unity projects. This tight integration is useful if your buyers are Unity developers — but it creates a hard ceiling on who can buy your work.
Blender users, Unreal Engine developers, 3D print enthusiasts, architects, product designers, VFX artists, and hobbyists cannot purchase from the Unity Asset Store without a Unity account and installation. Your STL, GLB, or OBJ model — regardless of quality — is invisible to them.
Proofly is engine-agnostic. Any buyer with a payment method can purchase your files. If you create characters that could serve both Unity game developers (as FBX rigs) and 3D print enthusiasts (as STL), Proofly lets you sell both use cases from a single listing — reaching a far broader audience than the Unity ecosystem alone provides.
The 3D Viewer Gap: Static Screenshots vs Real-Time Preview
Unity Asset Store asset pages rely entirely on screenshots and preview renders that the publisher uploads. Buyers cannot rotate the model, inspect topology, view wireframe, check mesh quality, or measure dimensions before purchasing. The decision to buy is based on how well you staged your promotional images — not on the actual model quality.
Proofly embeds a full WebGL 3D viewer on every listing. For STL, GLB, OBJ+MTL, FBX, and 3MF files, buyers can:
- Orbit, zoom, and pan with mouse or touch
- Toggle between solid, wireframe, wireframe-only, matcap/clay, and X-ray display modes
- Switch between Studio, Outdoor, and Dark lighting presets
- Measure point-to-point distances on the mesh
- View bounding box dimensions in mm, cm, or inches
- Check polygon count and watertightness status
- Play back animations in GLB and FBX files
- Take a screenshot from any angle
This level of transparency increases buyer confidence and reduces refund requests — buyers know exactly what they're getting before they click purchase.
Piracy Protection: What Happens After Download
Unity Asset Store offers no per-buyer piracy protection. Once a buyer downloads your asset, there is no fingerprint in the file linking it to them. If they redistribute it — uploading to free model sites, sharing in a game dev Discord, or reselling it — you have no forensic trail to identify the original buyer.
Proofly includes HiddenMark™, a steganographic watermarking system built into the platform. When a buyer purchases an STL file, HiddenMark™ embeds a unique, invisible fingerprint into the mesh geometry before delivery. The watermark:
- Is unique per buyer — two buyers get the same model with different watermarks
- Is invisible to the naked eye and does not affect print quality
- Survives basic mesh editing, scaling, and format conversion
- Can be decoded by Proofly to identify who shared the file
- Provides legal standing for DMCA takedowns and cease-and-desist letters
- Acts as a deterrent — buyers who know files are watermarked are far less likely to share them
For creators whose models are routinely pirated on sites like Thingiverse, Reddit, or Telegram groups, HiddenMark™ changes the calculus — you can now identify the source of any leaked file.
Format Support: Beyond Unity Packages
Unity Asset Store is designed around the Unity import pipeline. While FBX and OBJ are technically supported, most serious publishers package everything as .unitypackage to ensure correct material assignments, prefab hierarchies, and shader configurations for Unity. STEP files, 3MF, STL (3D printing format), and BLEND files are rarely listed and not supported as first-class formats.
Proofly supports the full range of 3D formats used across all disciplines:
Every format that can be previewed in the browser gets the viewer automatically — no extra configuration needed when uploading.
Analytics and Creator Dashboard
Unity Asset Store provides a basic publisher dashboard with sales figures and revenue history. There is no breakdown by region, no view-to-purchase conversion rate, no per-listing traffic analysis, and no insight into which listings are attracting views without converting.
Proofly's creator dashboard includes: total views and sales per listing, view-to-purchase conversion funnel, revenue over time (daily/weekly/monthly), geographic breakdown, top-performing models, and earnings by currency. These metrics help you understand which models to promote, which to reprice, and where your buyers are coming from.

Frequently Asked Questions
What commission does Unity Asset Store charge?
Unity Asset Store charges a 70/30 revenue split: creators keep 70% and Unity keeps 30% of every sale. On a $20 asset sold 100 times per month, Unity takes $600 — $7,200 per year from that one asset alone. The split applies to all asset types including 3D models, textures, audio, scripts, and complete project templates. Proofly charges sellers 0% commission — only the buyer pays a flat ~$1 service fee, and sellers receive 100% of the listed price minus standard payment processor fees.
Is Unity Asset Store limited to Unity-only buyers?
Yes. Unity Asset Store is purpose-built for the Unity game engine ecosystem. Assets are delivered as Unity packages (.unitypackage files) designed to be imported directly into a Unity project. Buyers must have Unity installed and a Unity ID to purchase. This means your GLB, FBX, or STL models are only accessible to the subset of buyers who use Unity — not Blender users, Unreal users, 3D print enthusiasts, architects, or product designers. Proofly is engine-agnostic: any buyer with a credit card or PayPal can purchase your STL, GLB, OBJ, FBX, or 3MF files, regardless of what software they use.
Does Unity Asset Store have an in-browser 3D viewer?
Unity Asset Store does not include a real-time in-browser 3D viewer. Asset pages display static screenshots and promotional images provided by the publisher. Buyers cannot rotate, zoom, inspect topology, check wireframe, or measure model dimensions before purchasing. Proofly includes a full WebGL 3D viewer for STL, GLB, GLTF, OBJ (with MTL material files), FBX (including animation playback), and 3MF. Buyers can orbit the model, toggle wireframe and X-ray modes, measure point-to-point distances, view polygon count and bounding box dimensions, and check watertightness — all before purchasing.
Does Unity Asset Store offer piracy protection for 3D models?
Unity Asset Store does not offer per-buyer piracy protection. Assets are delivered as Unity packages, and once downloaded there is no fingerprint linking a specific file to a specific buyer. If a buyer re-uploads your asset to other marketplaces or shares it in Discord, you have no forensic trail. Proofly's HiddenMark™ system embeds an invisible, steganographic watermark into every STL mesh before delivery. The watermark is unique to each buyer, is not visible to the naked eye, survives basic editing and format conversion, and can be decoded to identify exactly who shared the file — giving you legal standing for DMCA takedowns and a strong deterrent against redistribution.
What 3D file formats can I sell on Unity Asset Store vs Proofly?
Unity Asset Store is optimized for Unity-native formats: .unitypackage, FBX, OBJ, and PNG/TGA textures packaged for Unity. Models must conform to Unity's import pipeline. STEP, 3MF, STL, and other non-game formats are rarely listed and typically unsupported by buyers. Proofly supports the full spectrum of 3D formats: STL (with watertightness checking), GLB/GLTF (with PBR material preview), OBJ + MTL (companion material files extracted automatically from ZIP), FBX (with animation playback in the viewer), 3MF, STEP, BLEND, and ZIP packages containing multiple formats. All previewable formats get the in-browser 3D viewer automatically.
Can I sell on both Unity Asset Store and Proofly at the same time?
Yes. Proofly has no exclusivity requirement, and Unity Asset Store's publisher agreement does not prohibit selling on other platforms. A common strategy is to continue listing Unity-specific .unitypackage assets on the Asset Store for the Unity community while building a Proofly catalogue for format-agnostic buyers (Blender users, 3D print enthusiasts, Unreal developers, product designers) who don't need Unity-specific packaging. Over time many creators shift their primary promotion to Proofly as their audience grows — because every sale there returns 100% of the price to them.
How long does it take to migrate from Unity Asset Store to Proofly?
Migration takes 10–20 minutes per listing. (1) Create a free Proofly account and connect Stripe for payouts. (2) Export or locate your original model files (FBX, OBJ, GLB, STL) outside of the Unity package. (3) Upload each model to Proofly — add the same title, description, tags, and preview images, and set your price. (4) Enable HiddenMark™ to activate per-buyer piracy fingerprinting. (5) Add your Proofly shop link to your Unity Asset Store publisher page, portfolio, and social accounts. You can keep Unity Asset Store listings active while building your Proofly catalogue — there is no conflict or exclusivity clause.
Who should use Unity Asset Store vs Proofly?
Unity Asset Store is best for creators selling Unity-engine-specific assets: C# scripts, shader graphs, editor tools, Unity prefabs, complete Unity project templates, or models packaged specifically for Unity import. If your buyers are Unity developers and your assets rely on Unity-specific features, the Asset Store gives you direct access to that audience. Proofly is better for creators who: sell format-agnostic 3D models (STL, GLB, OBJ, FBX, 3MF) that buyers across multiple platforms and engines want; sell to 3D printing enthusiasts; want buyers to inspect models in a real-time viewer before purchasing; want per-buyer piracy tracing via HiddenMark™; want 0% seller commission; or are tired of being limited to Unity's audience.
