Explanation: Early in Half-Life 2's development, all model folders were prefixed with W_, possibly meaning 'world', like with the world models of weapons.Examples: The entirety of the 'Bathroom' /materials/models/ folder, W_Stalker, the entirety of the 'Electronics' /materials/models/ folder.Identification: Does this folder start with W_? If so, it is likely this.In early stages of the game, they used styles of texturing they were very familiar with, which happened to be ones similar to the ones they used in Half-Life 1. This is especially applicable with Half-Life 2's developers. Examples: Odell, Jaytest, Helena Mossman, Police, TBot1, Combot.Does it look like only one side of the model? Like someone took a photo of the front of it and molded it into a texture? Then it is likely this era. Identification: Observe how the texture looks.Half-Life 1-esque 'side-by-side' Texturing There isn't a lot of accuracy, but good estimates are definitely possible to make. Texture identification isn't the best method, but one thing it is is consistent. From the gradual progression of 'side-by-side' texturing to using texture sheets, from Version 27 models to 37, and especially in the sound files that still bear dates of when they were created. Half-Life 2 has had a long and diverse development, and this is heavily reflected in the Leak. 3.2 Leftover Pre-Physics Death Animations.2.1 Half-Life 1-esque 'side-by-side' Texturing.
