In order to increase the reading speed of the model and reduce the load on the server, VRoid Hub generates an optimized model from the uploaded VRM model to display in your browser.
As a result, there may be a slight difference between the model displayed VRoid Studio and the model displayed on the VRoid Hub.
VRM files that can be downloaded from VRoid Hub (of your own models or of models that allow third-party use) are the original VRM files before optimization.
