Half-Life 2 (Windows)/Unused Models
This is a sub-page of Half-Life 2 (Windows).
A weird, chrome-textured "silhouette" model of Half-Life Gordon can be found. It was clearly not meant to ever be seen in gameplay as it is more or less a statue, possibly used for referencing where the player would be standing. It can be seen via the thirdperson console command, and even has animations when used on NPCs.
Explain the difference between the used model, and this one.
A lightly rebranded Arriflex 435ES movie camera with a highly detailed model. Also exists in Team Fortress 2.
In the shadertest folder, there are five identical models called shaderslab1-shaderslab5, each with different textures. It is, as the name implies, a slab used to test shaders on. These models are used in test_hardware from Counter-Strike: Source.
The perftest folder contains a few resources, mostly from the original Half-Life, that were used for testing.
HL G-Man. His original animations exist. This model and his animations can be found in Source Filmmaker, in the same directory.
grass_tuft_001.mdl - grass_tuft_004d.mdl are missing their textures. They're supposed to be grass tufts, hence the name.
The Loader. Original animations also exist.
A bunch of different rock pile variations also missing textures.
Nvidia SHIELD test models
These models are high-poly test models. These were also used in the map devtest_highpoly.bsp in the Android port of Half-Life 2 released for the Nvidia SHIELD.
