Epic's licence exempts a free configurator from its royalty

The picture

Epic Games' Unreal Engine End User Licence Agreement, current as retrieved 16 September 2026, sets out Royalty-Free Distribution categories in Section 4(a). One is "Indirect Revenue": a Product that does not directly generate revenue owes no royalty, illustrated by the licence's own example — "Distribution of a free car configurator app (a Product) used to sell cars will not result in royalties owed on sales of the cars themselves, even if the sales are made via the configurator app." This matters for any manufacturer running a public-facing Unreal configurator, a use case Unreal's own automotive page lists as a current stated capability: "build photorealistic configurators."

What the documents show

The EULA's exact condition is that "no revenue is attributable to any Product access, including features and functionality within the Product, or to any in-Product benefits." The exemption attaches to the configurator app itself generating no direct revenue, not to the underlying product being sold. The same section separately lists other royalty-free categories — internal company-group use, single-client work-for-hire, and use confined to a physical location such as an arcade or ride — each with its own distinct condition, none of which is the indirect-revenue test. The automotive page confirms configurators remain a current use case but does not itself restate the licensing condition.

What it is allowed to decide

This licence text does not, on its own, decide whether any specific deployed configurator actually qualifies. It sets the condition a deployment must meet: no revenue directly attributable to the app's own access, features or in-Product benefits. A configurator that also processes payments, sells upgrades, or otherwise monetizes access within the app would fall outside this specific exemption — it is conditional on the licence's own structure, not unconditional for every free-to-use tool. This is a financial and legal classification of a Class 3, Commercial artifact, not an authority claim about the image itself: the EULA text establishes nothing about whether the configurator holds Photometric or Dimensional authority, and does not address hybrid models that mix indirect and direct revenue.

The disclosure label

A manufacturer's configurator could carry a label stating: this application is distributed under Epic's Unreal Engine EULA Section 4(a)(ii), current as retrieved 16 September 2026; it qualifies for the indirect-revenue royalty exemption only if no revenue is directly attributable to access or in-app features; it does not hold this exemption if the app itself monetizes access. A licensee's legal or licensing counsel would plausibly assert this label before public release.

• Does the deployed configurator charge for any in-app feature, upgrade or access, which would break the "no directly attributable revenue" condition?
• Is the configurator's revenue genuinely indirect, tied only to a separate physical-goods sale, or does it blend indirect and direct models the licence's plain example does not address?
• Has this EULA text changed since last reviewed, since it is a living document Epic can update?

A free tool is not automatically royalty-free; the licence conditions the exemption on how revenue actually attaches. Reading the specific clause, not the general habit of assuming configurators are exempt, is what this entry's sources actually support.
