replace

Hey guys. In short , I would like to replace the crocodile model for a different one for sharkbay but i dont know how. Func_croc only makes a crocodile appear. it doesnt have any other options. Someone told me to rewrite the code of func_croc for the map but I am not sure how this is possible...

Hi so I made a map and I need to change the path of textures on some of my brushes. Question is can I do that with anything similar to the "Replace..." function in edit tab?
