Amazing plug-in and responsive dev! I've been hoping to play MMD files since the early days of VAM, and here it is!
The price is definitely steeper than other plugins but it's well worth it if this is what you're looking for.
Looking for motion files may be jarring to those unfamiliar with MMD. So I think it would be nice if the dev included a sample pack of motion + audio or a sample scene to get people started.
Due to the 1.20 update, there are a few bugs, but the dev has been quite helpful in troubleshooting and seems to be working on fixes to be released soon.
The dev plans on adding new features, and have done so already. I just hope that they keep it up!
