Get sound and/or desktop notifications when an animation is finished rendering. Easy and simple- just install, and click "Render Animation"!
Blender doesn't tell you when an animation is done rendering, which can lead to valuable time lost waiting. RenderNotify gives you the option to get desktop notifications and sound notifications, so even if you're in another room, you'll always know exactly when your render is done.
To use sound notifications, turn on Sound in the Add-on Preferences, and choose a sound. (RenderNotify does not come with a sound, however, the default desktop notification sound will play if nothing is selected.)
Desktop notifications work on MacOS, Linux, and Windows.
NEW IN 1.1: Toggle desktop notifications (on by default)
