This addon replaces the metal Cargo Container prop with a higher-poly model, aiming to improve the realism and visual quality of the game. *Important*. There was a bug with the original file that made hosting a server running a map with one of the prop_wasteland variations of the crates absolutely unplayable. This is now fixed.
This model was orignally flat-faced, with little detail on either side. The texture was flat and behaved too statically to appear realistic when moving. I rebuilt, or "Traced" the model with brushwork in Hammer World Editor, then sculpted details using the advanced tools provided. I exported the brushwork as a replacement prop using Propper, an addon for Hammer, then edited the materials to include bumpamps and Phong Shading.
This addon does not allow you to have any advantage over other players in the game, and will not break consistency rules on servers that enforce them. This was designed for CS:S, but may work with Hl2 (Untested). Feel free to use/share/edit this addon as you please, just make sure to include the packaged .TXT file.
