The planet's texture was made from scratch using real data from Voyager 2 as reference, due to the original data being too low in quality for use in a feature film. The airbrushed map was posted in a blog about how they made Jupiter in the film.
Here's what the texture looks like:
While it is kinda dated as of now (especially because we now have higher resolution textures of the planet made from data from other spacecraft), I would like to see if I can try to make this texture usable by upscaling it, cleaning it up, and color-adjusting it to look more visually appealing for use in Celestia, and 3D renderings. That is, once I either get my current PC repaired or, more likely, get a new PC and have everything transferred to it.
