Hey Guys,
i am very new to the Half-Life "Modding" (if you can call it that). My problem right now is, that i changed the the back of Barneys Model, and it loads everything correctly in Jeds Model Viewer. The texture hast the same resolution and bit depth. However, when i restart Half-Life, Barney still has the original old Back Texture.
Thanks for everybody, who can help out!
