already been made but that's not ideal. Better would be if I could take the textures used to render the skybox, upscale that, then the skybox could be re-rendered using that.
Well I can help a bit with that. I am no artist, but I can help take the art and make the skybox.
I have access to Pano2VR which has the ability to render a skybox from the input images.
However, there may be a hole that needs to be patched at the very centre of the skybox. Thats where an artist is very useful.
