The Transparency Trick was a bug that could have been done from 2007 until 2009. There are some body colors on ROBLOX's body color change that make you white. When the old studs were still on ROBLOX this Trick/Glitch was possible. It was only available to the ROBLOXians who had the old, solid body (Used from 2006 - 2009). When the old studs where being used, the body texture and the Java-Script HTML was more different than today's bodies, and caused a Transparency Glitch, making your character invisible. If you made your body invisible and then put a certain T-Shirt or Shirt or Pants on, you would look like a certain object. But since the body updates, the glitch is no longer possible. People often exploit the body to look like the old studs, thus activating the glitch. It is sometimes found on abandoned ROBLOXians.
