3D Audio

is rare that an 3d engine does not have a 3d audio, even if is baisc, openal or something, neither in the roadmap.

1+ I noticed that sound position data does not reflect in stereo

Hi all- the audio system is fully 3d (7.1 spatialized) for mono sources. Stereo sources will attenuation but not pan; if you need panning multichannel audio, this can be set up via a positional blueprint. While not explicitly on the roadmap, we are working toward more advanced audio features and implementation.
