Somes peoples says they have models/bugs textures.
I've check again your screenshots and i see no texture bug. The textures or models who are in error ingame (please continue to send me screenshots of bug that you encounter) are native half-life 2 (ep1/EP2) textures/models.
Please be sure you have "half-life 2 : Episode 2" installed. If bug are not solved be sure "Half-Life 2" and "Half-Life 2 : Episode One" are installed too.
Remember, if you want to contact me :
Thank you and enjoy Combat-Alpha !
