Rumors of GSC Game World using graphical assets from Valve's Half-Life 2 and id Software's Doom 3 for us in S.T.A.L.K.E.R.: Shadow of Chernobyl have apparently been debunked.

The water textures that were mentioned in our post on the issue were apparently gotten by BOTH Valve and GSC Game World from Marlin Studios. Marlin provides all kinds of textures for a variety of uses, including stuff like sci-fi textures and even Elvis.

As for the light texture that was allegedly taken from Doom 3, reports say that it's "just a standard Impact Light texture, rather than referring to the Doom 3 monster."

id Software Todd Hollenshead has already expressed concerns about the whole issue, but also noted that "it would be improper to make any decision about a course of action until we find out whether the claim is true." We guess waiting for more details to come to light paid off.
