Deadline vgui .VMT File
This is an example of a .VMT file, included with the sample Deadline campaign, that is associated with interface elements such as loading poster, map thumbnails, etc. Feel free to use this as a template for your own custom addons.
// This .VMT file is referenced in the missions/xxx.txt file as the loading poster.
// It, in turn, references the image LoadingScreen_Deadline.vtf in the "$basetexture" key.
