I’ve come across a number of users on DeviantArt who use either Roblox Studio (the better choice) or Roblox itself to make images (or in some instances, GIFs and MP4s). I’ve been told by a couple of users I’ve asked that they simply apply multiple ball props to a player model, but I feel that being told that isn’t enough, especially in Roblox Studio’s case. And there’s hardly any tutorials on DA regarding making fat/inflated avatars in Roblox Studio.
Probably cus it still has a mostly underaged user base.
I have seen many props in the toolbox in roblox studio related to weight gain and/or inflation, most of them are in a black box in the thumbnail though because otherwise roblox removes them, but if you place them down you can just remove the box and its.
Also dont publish a game with one of these props in it or you might get banned, but you can still test the world in roblox studio and play it with out publishing its ready to go.
And also there is someone who disguises a noise machine that you cant turn off as a weight gain/inflation thing, wich you should watch out for.
edit: i just went into roblox studio and noticed that most of the wg and inflation stuff has been deleted by roblox
