doclan Thanks for your answer. My intention is to download a vrcw file to get the 3d models (human) that are inside that file, i guess those must be there like it happens in the other worlds from the sanrio vfes. This event is like watching a show, so all the models and animations are inside the world file, at least the official sanrio ones (i'm not really certain if the invited artist are there).
I finded the other worlds id here (https://en.vrcw.net/category/detail/sanriovfes?orderby=update), i guess if i can find the ids of the paid ones, it would be possible to download them through this website.
I'm not really familiar with vrchat, so if you could share some tutorials to get that id or that booth thing i'd appreciate it very much. About the model assembly it's ok, i tried assetstudio and blender and everything looks ok there.
sorry for weird phrasing or typos, english isn´t my first language. thanks for your time!
