Urho3D 1.7 Released

/ News /

Somewhat belatedly announced (by me), Urho 3D 1.7 was released last week.  Urho is an open source 3D game engine available here.  I coveredlogo a previous version of the Urho game engine as part of the closer look game engine series if you wish to learn more.  Urho is also the underlying technology behind the Atomic Game Engine as well as Xamarin’s C# port, UrhoSharp.

Urho 1.7 brings several new features including inverse kinematic (IK), Apple TV platform support, WebAssembly compilation and much more.  Details from the release notes:
