Studs

Studs are textures that are placed on parts. The original studs were 3D, from around 2004-2005 and had no branding. In 2006, studs were changed to a flat texture. They resembled a Lego stud, with there being a 'R' placed in the middle instead of the Lego logo. This version of studs is commonly referred to as circle studs. In 2009, studs were changed to a square with no logo. This caused many people to believe that Lego sued Roblox for copyright infringement though while not actually being the case. Later that year, studs regained their 'R' branding. This version of studs is referred to as a square stud. Around Late 2013, studs were updated to have the 2013 'R' from the logo at that time. In early 2017, the Studs changed to the new logo. Around mid 2017, studs finally were changed to remove the branding entirely. Currently, ROBLOX uses the brand-less studs from 2017. '''As of May 2021, studs are only available in Roblox Studio by copying a part that has them, or by using plugins. The surface tool has been removed.'''
