Why do you keep putting weird edgy thumbnails that are completely unrelated? Why don't you, I dunno, put a preview image of the things you are uploading?
what about the one literally the same as this that was posted a year ago, that gives you the shader need and has been the top downloaded model here for a long time
1.) turn your model around. lol 2.) visemes worked on the 4 models i tested it on. your model may be translated differently, so this may not work onnall models.
3.) yes. it is a direct conversion of the original mmd motion to unity.
