Hi,

Anyone can tell me how i cant prevent the camera to show the inside of my model, when i use a gun in the view like a FPS?

Maybe i need to use another method than that...

ENTITY* actor_screen =
{
type = "ak47.mdl";
layer = 1;
flags2 = SHOW;
x = 30;
y = -3;
z = -5;
}

check if your textures are 32-bit. It yes, change them to 24-bit

If you are making an FPS then making a view entity is your best option. It will not run into the camera and it will not go through walls either

View entities for FPS weapons isn't the best idea... You'll miss the main thing, lightning on your models...
To make weapon do not pass through the walls just set ZNEAR, and make sure to have camera clip near set to zero.
About seeing model from inside, using view entity will not fix that, the problem is in the alpha channel that models probably has.
Export skin to .PCX in MED, and then import it back (it will make 24bit skin).
