Hello there, long time member of Moddb and part of the Half-Life modding community since the very beginning! Currently working on the brand new Half-Life mod "Dark Matter".
Sorry guys, been pretty busy with real life so it's taken awhile to get this update posted.
Here's the new version of the exterior of the building sporting brand new textures that have natural lighting and look like the stone they're supposed to. This is a partial reconstruction with more details and to match the quality of the interior more.
Obviously both inside and out will be damaged in the final versions...
