MMDEditor pack contains the latest SuperMode, MMDPlayer, RenderToMovie, RenderToVR, and FastVaM plugins.
MMDEditorPack 4.3.0 update:
Fixed issue that MMD dance pose remains even when switching to another scene without MMD plugin.
Fixed issue that Supermode plugin doesn't remove correctly when closing a scene
RenderToMovie automatically includes the scene audio into the rendered video also for non-MMD mocap scene animations. It exports two videos, one with audio and the other file name starting with "s"(for silent) without audio.
RenderToMovie captures the visual effects triggered by scene audio into the rendered video also for non-MMD mocap scene animations. There is a great plugin Sally.SallySoundFX with which you can easily set up audio triggers. Audio triggers are typically used to change the intensity of lights to achieve nice light-sound-sync effects like this video.
