The code works in the editor but does not work on Build (EXE File).

the code load images and build from them a SkyBox.

Files of the SkyBox are on the right paths (Copied manually)

Have you confirmed your directory / path is correct after building? Have you duplicated these assets into an Assets\Skybox folder after your game builds? Are you sure Directory.GetCurrentDirectory() is giving you the right base path after building?

yes yes and yes i put a textinput ui and insert to it the Directory.GetCurrentDirectory() + “\Assets\SkyBox\Front.png” code and i get the correct folder.
