I was looking into a really necessary function for me when using Blender. I need Blender to play a short mp3 sound when it finishes rendering. I found this on the API:
Callback list - on completion of render job
And this script .py (addon) sends email notification, but I was really looking for .mp3 playback of a sound. Say for example if you are away from the computer, then you´ll hear the render fininsh. https://archive.blender.org/wiki/index.php/Extensions:2.6/Py/Scripts/Render/Notify_after_render/
But I don´t have a way to put this all together. Could someone point me with another script?
