Hello I am a student from Harllee Middle School and I have accidentally wrecked two 2d levels but I have a former game that can work for what I need and it is exported onto a DVD. This is amazing exept for the fact that I need to modify 3d text. If anyone knows how to modify an exported game that would be amazing.
You can modify it with a hex editor. If it's just text you're trying to change, it might work, although the number of characters will have to be exactly the same.
You can't modify a game once it's been compiled by Unity, and you can't decompile it. I'm not sure what you're trying to do, but you're going to have to find another way to do it.
I'm sorry but this isn't going to work. You are just going to have to redo the stuff you wrecked. :(
