Is The Skin Black 'n' Pink 4 u ?
Q : My skin turned out to be pink and black checkered in the game and I know I installed it right! WTF??????
A : In most cases someone didn't submit the file right. I know in some skins (like the black m134 Vulcan mini gun) you get pink and black textures. Fortunately, there is way to fix it!
1) Go to counter-strike source\cstrike\materials
2) Right click the folder weapons and click cut. (Control+X)
3) Now go to ...\counter-strike source\cstrike\materials\models\
4) Right click the background of this folder and click paste (Control+V) and select yes to all.
5) Now your skin is fixed
In other cases the folder that you have to move will be somewhere else. The easiest way to find out is to open the zip/rar file for the skin, and then explore into the materials folder to see what folders were placed wrong.
