Help making a sphere that looks like a skybox

Hi everyone, i have a game where I needs to create a sphere around the character, but i need the sphere to look like a skybox, but only inside the sphere, without changing the skybox of the scene and without looking like a texture placed on the sphere, is there a way to do this?


I’ve seen a guy called Oda doing something similar to what I am looking for in a video called “CRIEI UM JOGO DE JUJUTSU KAISEN!” using a skysphere, but it was in Unreal

For one it needs to be HUGE. This is much too tiny, sky is infinite it should look infinite.
