Total newb to Unity, so forgive my stupidity please.
In the game Buzz Aldrin’s Space Program Manager there are files that use the unity3d extension (e.g., “ASTRONAUTS-F1001.unity3d”). I believe they’re headshots of the astronauts in the game and said pictures are terrible and immersion-breaking. I’d like to change them - that is, replace the current images with some of my own.
How would I access the files and then (if I can replace them with a better image) put the extracted/decompiled/whatever files back into unity3d format?
I believe the game was made in Unity 4 if that helps.
Thanks in advance!

PS - if this should be posted in another place, please let me know.
Moved to general discussion although there’s no reason why anyone here would be able to help you. Only the developers of the game would know how to modify their game, assuming it’s possible. Nobody here would have that kind of insight.
Thank you for answering (and moving the post!) I guess I just figured that a Unity file is a Unity file, regardless of the game, so maybe I could “open” it (or access it somehow). But if it’s not possible, then I’ll just suffer with poor pictures.
The .unity3d file extension was used for the old web player. The web player has been defunct for a while now. So it looks like the dev has just made their own file format and reused the name. Asking the developer for assistance would be the best bet.
However if you want to go nuts in the traditional modding fashion, I would simply try changing each the extensions on the files to match the most common image types (.png, .jpg, and so on). Then see if you can open the file in a regular image editor. If that doesn’t work, try the various compression formats. There is a small chance the developer has been lazy and one of these formats will actually work for you.
It’s distinctly possible that it’s an Asset Bundle. If so then possibly just trying to open it with a versatile archive tool, such as 7zip, might get the job done.
However, if so, the contents probably aren’t going to be an image editor friendly format like PNG or JPG. They’ll probably be a GPU-friendly format such as DXT or whatever, and possibly atlassed.
Each of those things can be worked around, of course. There’s no magic, it’s all just data. The question is, how long do you want to spend changing the images in a game?
