Cubebrush charges a 30% commission on every asset sold — meaning you keep only 70 cents of every dollar your work earns. On 500 sales of a $15 asset, that's $2,250 paid to the platform instead of to you. Proofly charges sellers 0%: only the buyer pays a flat ~$1 service fee, and you keep the full price. This guide compares both platforms across the things that actually matter to 3D model and game-asset creators.

Cubebrush is a game-art marketplace built primarily for 2D concept sheets, brush packs, and game-engine assets (FBX, OBJ). It charges 30% commission on every sale, has no in-browser 3D viewer, and offers no per-buyer piracy tracing. Proofly is a dedicated 3D model marketplace: 0% seller commission, a full WebGL viewer for STL/GLB/OBJ/FBX/3MF, and HiddenMark™ steganographic fingerprinting on every download. If you sell 3D models — especially for print — Proofly keeps more money in your pocket and gives buyers a better pre-purchase experience.

Cubebrush (cubebrush.co) is an online marketplace originally launched for game artists, concept designers, and digital illustrators. It hosts digital assets across multiple categories: 3D models (typically in FBX, OBJ, or Blender format), textures and PBR material packs, 2D concept art reference sheets, Photoshop and Procreate brush packs, and video tutorials.
Its audience skews toward game developers, indie studios, and concept artists who need ready-to-use game assets. The platform has built up a catalogue of thousands of assets and an established buyer community in the game-art niche.
The key limitation for creators who sell 3D models is the commission model: Cubebrush retains 30% of every sale. At the same time, it does not offer an in-browser 3D viewer (buyers purchase based on screenshots), and there is no per-buyer tracking of downloads — meaning a pirated copy cannot be traced back to the specific buyer who shared it.
Thirty percent sounds abstract until you calculate it across a full year of sales. Here is what that commission gap looks like in dollar terms at common price points, comparing Cubebrush (30% platform cut) with Proofly (0% platform cut — buyer pays a flat ~$1 fee, you keep 100% of the listed price):
| Your price | Cubebrush payout | Proofly payout | Difference per sale | Diff · 500 sales |
|---|---|---|---|---|
| $5 | $3.50 | $5.00 | +$1.50 | +$750 |
| $10 | $7.00 | $10.00 | +$3.00 | +$1,500 |
| $15 | $10.50 | $15.00 | +$4.50 | +$2,250 |
| $20 | $14.00 | $20.00 | +$6.00 | +$3,000 |
| $30 | $21.00 | $30.00 | +$9.00 | +$4,500 |
| $50 | $35.00 | $50.00 | +$15.00 | +$7,500 |
| $100 | $70.00 | $100.00 | +$30.00 | +$15,000 |
Example: A creator selling a character FBX pack priced at $20 and making 500 sales per year earns $7,000 on Cubebrush and $10,000 on Proofly — a $3,000 difference per year from the same work. The Proofly buyer still pays $21 total (your $20 + the $1 service fee), so your listed price remains competitive.
On Cubebrush, buyers purchase based entirely on static images, screenshots, or rendered previews the seller provides. There is no way to orbit the model, inspect topology, check mesh quality, or view the asset in wireframe before buying. This creates friction for buyers of 3D models specifically — a potential source of refund requests and buyer hesitation.

| X-ray / transparent mode | No | Yes — see internal geometry |
| Normals visualisation | No | Yes — RGB normal mode |
| Matcap / clay mode | No | Yes — lavender clay shading |
| Animation playback (GLB/FBX) | No | Yes — play/pause/scrub/speed |

| Formats supported | — | STL, GLB, GLTF, OBJ+MTL, FBX, 3MF |
A buyer who can orbit and inspect your model in the browser before purchasing has far more confidence in the quality of what they are buying — which means fewer refund requests, more conversions, and better reviews for sellers.
3D model piracy is widespread. Downloaded FBX or OBJ files can be re-uploaded to free repositories, shared in Discord servers, or sold on competing platforms within hours of a legitimate purchase. Without a way to trace which buyer shared a file, you have no legal ground to stand on and no way to send a DMCA notice to the correct party.
Cubebrush offers no solution for this. Once a file is purchased and downloaded, the platform has no mechanism to trace leaks back to a specific buyer.
HiddenMark works by altering vertex positions in the 3D mesh by amounts below the threshold of visual perception — the change is invisible to both the human eye and standard slicer previews, but detectable by the Proofly verification system. The code is unique to each purchase transaction, so the leak traces back to exactly one buyer.
If you make 300–1,000 sales a year on Cubebrush, the 30% cut compounds quickly. Moving to Proofly — or simply dual-listing — recovers that margin without changing your prices.
Cubebrush's audience is primarily game artists, not 3D print creators. Proofly is built for print files — watertight mesh checking, STL viewer with manifold analysis, and a buyer community of makers.
FBX and OBJ game assets are trivially re-shared on Discord and Telegram. HiddenMark™ embeds a per-buyer fingerprint in STL meshes, and Proofly tracks download events per buyer — giving you a trail when files leak.
Proofly's in-browser 3D viewer means buyers can inspect your model, check geometry, and orbit around it before purchasing — reducing blind purchases and refund requests.
Proofly gives each creator a public profile, a shareable shop link, and follower/notification features — so repeat buyers can follow your uploads and you own the relationship.
Early sellers on Proofly earn Founding Creator status — permanent recognition, priority in search, and access to launch benefits. Spots are limited and close once the programme fills.
Cubebrush has an established audience of game developers, indie studios, and concept artists who specifically browse its catalogue for ready-to-use game assets. If most of your catalogue is:
— then Cubebrush's existing audience may convert better for you than building a new audience on Proofly from scratch. The right strategy for most 3D model creators is to keep Cubebrush listings live while running Proofly in parallel — capturing both audiences without giving up the commission-free earnings on Proofly.
The most efficient approach for most creators is not to abandon Cubebrush entirely — it's to add Proofly as a second revenue stream where you keep 100%, and use Cubebrush's traffic as a top-of-funnel.
Your Proofly listing earns you 100% of the listed price. Your Cubebrush listing earns you 70%. Both can live simultaneously — no exclusivity conflict.
Add your Proofly creator URL to your Cubebrush bio. Buyers who want a better preview experience or who find piracy protection valuable will follow the link.
Proofly buyers get a per-buyer fingerprinted download — a feature Cubebrush cannot match. This is a genuine selling point you can highlight in your listing description.
Proofly's analytics show view counts, conversion rates, funnel stages, and which models perform best — giving you data to improve listings on both platforms.
As your Proofly follower count and repeat-buyer base grow, directing new social promotion there returns more revenue per post — because you keep 100% of every sale it drives.
Migrating a listing from Cubebrush to Proofly takes about 10–20 minutes per model.

Cubebrush charges a 30% commission on every sale, meaning you keep 70 cents of every dollar earned. On top of that, payment processing fees (approximately 2.9% + $0.30) are subtracted from the seller's share. Proofly charges sellers 0% — only the buyer pays a flat ~$1 service fee, and you receive 100% of the listed price minus standard processor fees.
No. Cubebrush does not include an in-browser 3D viewer. Buyers purchase based on static screenshots and render previews only. Proofly includes a full WebGL viewer for STL, GLB, OBJ, FBX, and 3MF files — buyers can orbit, toggle wireframe or X-ray mode, measure distances, and inspect mesh quality before buying.
HiddenMark™ embeds an invisible steganographic code into every STL mesh download, specific to the buyer's transaction ID. The watermark alters vertex positions by sub-perceptual amounts — invisible to the eye, to slicer previews, and to basic mesh editors. If your file appears on a piracy forum, uploading it to Proofly's verification tool reveals the buyer who originally purchased it, giving you a name for DMCA takedowns.
Yes. Neither platform requires exclusivity. Many creators list on both: Cubebrush to reach its existing game-art audience, and Proofly to keep 100% of earnings from a growing audience of 3D model buyers. Linking from your Cubebrush profile to your Proofly shop is an effective way to capture buyers who prefer a platform with a proper 3D viewer and piracy tracing.
Proofly's in-browser viewer covers STL, GLB, GLTF, OBJ (with MTL materials automatically extracted from ZIP), FBX (with animation playback), and 3MF. All of these formats get native WebGL preview — buyers can orbit and inspect before buying. Cubebrush accepts most formats as file uploads but has no native viewer for any of them.
Yes. Creating an account and listing models on Proofly is free. Proofly's revenue model is a flat ~$1 buyer service fee per transaction — not a percentage of the seller's price. Sellers receive 100% of the listed price minus standard Stripe payment processing fees (approximately 2.9% + $0.30 depending on region).
Cubebrush is best suited for 2D concept artists, brush-pack creators, and game-engine asset sellers (FBX, OBJ) who already have an established audience on that platform. Proofly is better suited for 3D model creators — especially STL/GLB/3MF print file creators — who want buyers to inspect models in a 3D viewer, want per-buyer piracy tracing via HiddenMark™, and want to keep 100% of every sale. For most 3D model creators, running both simultaneously is the optimal approach.
List your 3D models on Proofly for free. No commission, no file-size caps, no blind purchases — every listing gets an in-browser 3D viewer and HiddenMark™ piracy protection from day one.
