Setting up Unreal Engine
If you're going to develop VR applications using Unreal Engine, the first thing you'll need, of course, is the engine. Let's walk through the process of setting it up.
What it costs
A natural question to start with when considering Unreal Engine is what it costs. The news here is good. Unreal Engine is free to download and use, and if you use it commercially, the terms are reasonable.
When you download the engine, you'll be asked to agree to one of two license agreements, depending on what you're going to be using it for. If you're a game developer and you make a game or application using Unreal and sell it, you'll pay a 5% royalty on gross sales over $3,000 per calendar quarter. If you don't sell your game or app, or it earns less than that per quarter, Unreal is free to use.
If you're using Unreal for something that isn't intended to be sold to the public (training simulations, architectural visualization, or anything else), Unreal is entirely free under the terms...
