A GUISkin is no more than a collection of GUIStyles.

When you have a large number of different GUIStyles to work with, you can define them all within a single GUISkin. This style is internal in Unity and can be used in published games for quick prototyping, or if you choose not to stylize your Controls.

By default, when you create a Control without defining a GUIStyle, Unity’s default GUIStyle is applied. Control appearances are dictated with GUIStyles. In Unity’s IMGUI system, you can fine-tune the appearance of your Controls with many details. However, there’s taking inspiration from an inanimate object such as a building or a vehicle and copying and pasting images of an actual charred body and inserting them into a game for all to see.Although Unity’s IMGUI system is mainly intended for creating developer tools and debugging interfaces, you can still customize and style them in many ways. There are buildings that are reminiscent of actual locations – in Modern Warfare II, for example – the hotel and the museum levels came under fire for being almost like-for-like copies of real-world locations. For example, in Grand Theft Auto, almost every vehicle is modelled on a real-world model.

Ultimately, art imitates life, and when a designer or a developer is putting together an asset, they’ll take inspiration from a real-life source. However, the evidence is staggering, and it does look like Valve simply took the images of a man who died a tragic death and laid them over a simple in-game model. There are many levels to this ‘controversy’, with some suggesting that it’s a mere coincidence that the real corpse and the in-game skin look so similar.

Following a little digging, the truth behind the character’s skin was uncovered. In a strange turn of events, a series of gory, graphic images were shared to a subreddit (that we won’t link here), and one user made the connection between one shot and the in-game skin used for Half-Life 2, and later, GMod. Reportedly, images of a real burned body were simply wrapped onto a character model, making for what players always thought was hauntingly realistic – but never real. Recently, it was revealed by a YouTube channel, Richter Overtime, that a ‘charred’ character skin in Half-Life 2 (and by association, GMod) is an in-game rendering of an actual corpse.
