Regarding 'MMD World'...

This time, we'll talk about MMD Worlds, which allow you to do MMD-like videos in VRChat. First, an MMD World is a world where your avatar can dance, using motions created with the assumption of use in 'MMD (=MikuMikuDance)', a tool for making 3D models like Hatsune Miku dance. While some worlds are compatible with all environments, opinions are divided among VRC users due to copyright concerns. I will only present the facts, so please research and judge for yourselves at your own risk. Q, Can I go there? A, There are worlds that violate copyright, such as ripping assets from existing games... However, in some places, worlds exist where 'the terms of all creators (music/motion/camera) are followed' or 'permission has been obtained from each creator (some of whom are individually supported)'. Q, What about photos? A, There are no issues with VRC's terms of service. However, there was an incident where a motion creator who was previously flamed issued a statement prohibiting photos. That world has a warning about this, so it's a no. For other cases, if you cannot determine whether your SNS posts comply with the terms of all creators (music/world/camera), it's best not to use them. That's all for the main topic! See you again another dayー.
