so basicly my guys left handed, ive tried to change it in options and everything and i dont kno how to fix it.

cl_righthand 1

If it is a custom skin, it may just be a left-handed skin and you should get a new one if you don't like it left-handed.

im pretty sure its not a custom skin cause i havnt done anything custom to my game.

Well, have you tried cl_righthand 1?

There's also a menu if you press H. I think if you go to the one that says "HELP" it's on there as "Use Right-handed Models". It's on the H menu somewhere.

Escape -> Options -> Advanced -> Weapon Hand: Right -> Apply -> OK -> OK -> Return to Game.

did that and it didnt work.

i looked at the skin and it said it was the default skin.

Make sure the Renderer is on OpenGL and not Software. Right-handed models do not work in Software mode.

Yeah, i can only use software mode, it says im not able to use the OpenGl.

Well, then you can't use right-handed models.
