Unity Asset Store and 3D printing: the gap Proofly fills
Unity Asset Store has been the primary marketplace for Unity game developers since 2010. It serves a massive community of game developers who need C# scripts, prefabs, shaders, and Unity-specific packages. However, it was never designed for 3D printing creators — there is no support for STL or 3MF formats, no print-focused buyer community, and no in-browser viewer that shows physical mesh geometry.
If you create print-ready 3D models, tabletop miniatures, architectural prints, or format-agnostic meshes that can be used across multiple software environments, Unity Asset Store simply is not built for you. Proofly is built specifically for this market: print-ready formats, per-buyer HiddenMark watermarking, and a full WebGL viewer so buyers inspect geometry before purchasing.
30% is a permanent tax on every sale you make
Unity Asset Store's 30% revenue share applies to every sale, permanently. There is no reduced tier for high-volume sellers, no pathway to a lower fee, and no way to negotiate. Every time a buyer purchases your asset for $30, $9 goes to Unity before you see a cent. At 200 sales/month that is $1,800/month — $21,600/year — paid to a platform for the privilege of listing your work.
Proofly collects nothing from sellers. Instead, the buyer pays a small flat service fee per order. Your listing price is your full income from sale 1 to sale 10,000. On the same 200 sales/month at $30: you earn $6,000/month on Proofly vs $4,200 on Unity Asset Store — $21,600/year more, without changing your prices or your workflow.
HiddenMark — per-buyer tracing Unity does not offer
Unity Asset Store has no per-buyer file fingerprinting. When a buyer downloads your model, they receive a plain file with no buyer-specific identifier. If that file appears on a piracy Discord server, a free download forum, or is redistributed in a Unity asset pack without your permission, there is no technical mechanism to identify the source — only DMCA requests that may take weeks or months.
Proofly's HiddenMark system embeds a unique steganographic code into the mesh geometry of every paid download — different for every buyer and every purchase. The watermark is invisible to the eye and survives common mesh transformations. If a file leaks, upload it to proofly.store/hiddenmark to identify the source buyer in seconds — no DMCA needed, no detective work, just the transaction record.
Dual-listing strategy: Unity for reach, Proofly for revenue
You do not need to leave Unity Asset Store to benefit from Proofly. Neither platform requires exclusivity for standard 3D assets. The most effective strategy is to list Unity-specific assets (prefabs, scripts, shader graphs) on the Asset Store for access to the Unity developer community, and to list format-agnostic meshes (STL, GLB, OBJ, FBX, 3MF) on Proofly for 0% commission and access to the broader 3D printing and maker community.
Proofly reaches buyers who do not use Unity at all: architects, product designers, cosplayers, tabletop miniature painters, and makers. These buyers are not browsing the Unity Asset Store — they need printable geometry, not game engine packages. Listing on Proofly expands your audience without competing with your Unity catalog.
