does anyone know how I can put as a background in the main camera a. jpg files? I tried to apply it to a plan to put in front of the camera but I do not like the effect. I do the skyboxes but comes out badly.
I think you want to make a real skybox. For that you need to check the render settings. There you can assign a skybox material for being displayed as a surrounding in your scene. Creating this materials is faily easy, just check the materials available. You only need to insert 6 textures that are generated from a panorama, serie foto’s or maybe already an available set of skybox textures.
Try to import standard assets > skyboxes ( I guess ) and you’ll see some textures there once import into your project.
Once done, you have a nice background for your game.
