Vegetation modelling and rendering middleware SpeedTree Modeler is being made available for $19 per month to Unreal Engine 4 subscribers.
This fee will be separate from the $19 per month subscription for UE4, and there will be no royalty, per-platform or per title fees attached.
This particular licence is only available for Unreal Engine 4 users, and cannot be used with other pipelines or outside the engine.
Free models will be available for the engine’s users on the SpeedTree website and eventually the Unreal Marketplace. Any trees created with the tool or bought from the marketplace will still be accessible if users cancel their subscription of the middleware.
The tech is the latest game development tool to adopt such a subscription model, with UE4 and CryEngine using a similar payment method for developers.
