space-Urho3D
Urho3D implementation of https://github.com/wwwtyro/space-3d
The green arrow is the direction of sun, the directional light in the scene will also change its direction and color depends on generated sun.
Note: It only works in OpenGL and D3D11, I don't know how to do the blend mode in D3D9.
Modify Urho3D
To use it, one should add a blend mode for Urho3D, see files in engine_modification/
Build sample
Cmake as ordinary Urho3D project
