Can you tell me how to use it? I tried using what I thought was the method, but obviously didn't succeed.
Also, I'm not sure if our descriptions are consistent. What I mean is that switching cameras cannot maintain the shader effect. If two shaders are added, switching camera shaders will cause problems. So I need a solution to switch cameras while still maintaining shader effects. I tried downloading the js file from the link and replacing Old School.js. But obviously there is a problem. Actually, I'm not quite sure how this shader works
