I continue to make models based on Google images, this time here is such an unusual Inferno knife, it looks exactly like in the picture.
The quality of models and textures is good.
To make this knife appear in CJ's hand, press "F6", so that it disappears, press "Enter".
Installation: Transfer the files from the "gta3.img" folder to the "models/gta3.img" archive. Folders "cleo" and "data" transfer to the folder with the game.
