Best Cubebrush Alternative for Selling 3D Assets in 2026 — Keep 100% of Every Sale

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.

Quick answer

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.

What is Cubebrush?

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.

How Much Does Cubebrush's 30% Cut Cost You?

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 priceCubebrush payoutProofly payoutDifference per saleDiff · 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.

3D Viewer: Proofly vs Cubebrush

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.

Formats supportedSTL, 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.

Piracy Protection: HiddenMark™ vs Nothing

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.

Cubebrush

  • No per-buyer download tracking
  • No forensic watermark in file
  • No automated DMCA certificate
  • Cannot identify who leaked a file
  • No deterrent against sharing

Proofly — HiddenMark™

  • Unique steganographic code per buyer
  • Embedded invisibly in STL mesh vertices
  • Survives basic mesh editing
  • Identify leaker from any copy found online
  • Auto-generated DMCA certificate per model

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.

Who Benefits Most from Switching to Proofly?

High-volume sellers losing thousands to commission

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.

STL and 3MF print-file creators

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.

Game-asset creators worried about piracy

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.

Creators wanting better buyer conversion

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.

Artists building a direct audience

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.

Founding Creator programme

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.

When Cubebrush Still Makes Sense

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:

  • 2D concept art reference sheets or character sheets
  • Photoshop brushes, Procreate brush packs, or texture atlases
  • FBX/OBJ game-engine assets that need to land in a Unity or Unreal workflow
  • Tutorial videos or courses aimed at game artists

— 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.

Dual-Listing Strategy: Use Both Platforms

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.

  1. 1

    List your top models on Proofly at the same price

    Your Proofly listing earns you 100% of the listed price. Your Cubebrush listing earns you 70%. Both can live simultaneously — no exclusivity conflict.

  2. 2

    Link to your Proofly shop from your Cubebrush profile

    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.

  3. 3

    Enable HiddenMark™ on Proofly models

    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.

  4. 4

    Use Proofly analytics to understand your buyers

    Proofly's analytics show view counts, conversion rates, funnel stages, and which models perform best — giving you data to improve listings on both platforms.

  5. 5

    Shift promotion to Proofly as your audience grows

    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.

How to Move Your Models to Proofly

Migrating a listing from Cubebrush to Proofly takes about 10–20 minutes per model.

  1. 1

    Create a free Proofly account

    Sign up at proofly.store — it's free. Connect Stripe for payouts (takes 5 minutes — you'll need your bank details or a debit card to receive transfers).

  2. 2

    Download your original files from Cubebrush

    Grab the original STL, FBX, OBJ, GLB, or ZIP files from wherever you store your originals — not the sold copies. You need the clean source files to upload to Proofly.

  3. 3

    Upload to Proofly

    Use the Proofly upload flow: drag in your files, add your title, description, tags, and preview images. Set the same price as Cubebrush — your buyers on Proofly pay $1 extra as a buyer fee, but you keep the full listed amount.

  4. 4

    Enable HiddenMark™ on each listing

    Toggle HiddenMark on during upload. Proofly will embed a unique steganographic fingerprint into each STL download, linked to the buyer's transaction ID. If the file leaks, you can identify who shared it.

  5. 5

    Add your Proofly link everywhere

    Update your Cubebrush profile, ArtStation, Instagram bio, and any link-in-bio tool with your Proofly creator URL. Cross-promotion is the fastest way to build a Proofly audience from your existing follower base.

Frequently Asked Questions

What commission does Cubebrush charge?

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.

Does Cubebrush have an in-browser 3D model viewer?

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.

How does Proofly's HiddenMark™ protect my 3D models?

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.

Can I sell on Cubebrush and Proofly simultaneously?

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.

What 3D file formats does Proofly support that Cubebrush doesn't?

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.

Is Proofly free for sellers?

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).

Who is Cubebrush best suited for vs who should choose Proofly?

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.
