The outfit was taken from a MMD model from Deviant art, imported into Blender and then modified to then be imported into Unity via the "VRChat Creator Companion" editor... I edited the dynamics bones of the skirt using the tools provided by Vrchat to create the dynamism of the dress, then with the official VroidStudio add-on for Vrchat I imported the dress in "Xwear" format into VroidStudio and used it on my existing avatar... after making the necessary adjustments to the dress on the model I imported the model in the 2 possible formats, "XAvatar" and "Vrm", the model in Vrm has some problems I noticed with importing etc... however I think they are due to the fact that being a model created in beta it has the old import bugs, on the other hand the "XAvatar" is fantastic... importing a Vroid now into Vrchat has never been so easy... this feature alone can be used as an "official conversion system" for the Vroid Charater to use to upload them in Vrchat, and very simple and fast and no longer need to make additional changes between blender and unity useless.
