Borders can be tricky. Since I was upscaling an old file (I used Topaz Gigapixel) I still had to go in and fix the seams in Photoshop with a content aware brush. It's not hard, just annoying to do.

Looks amazing! I'm curious what tools you used for the upscaling; I made a small project a while back of trying to upscale skyboxes with Cupscale, but couldn't surmount the tedium of trying to manually fix the seams at the borders.

@AdamaVaille Make sure it's listed below any other mods that change things like lighting and any speed mods since those all make changes to Environment.sbc like skyboxes do and ones further down the list are loaded last, overriding ones further up the list. You want your skybox at the bottom of the environment stack so it doesn't get overridden by speed mods and lighting mods that alter the same file.

Hello, this is my first time trying to change skyboxes. Is there anything I have to do other than subbing and adding the mod to my mod list for the save?? I can't seem to get it to change.
