Thank you. That method didn't work for me, the game kept crashing, so I tried the method described in Borderlands 3's post, which ended up working for me. Here is what I did:
Use cheat engine to search for a float. The value you search for is 10% of the value you have the slider set to.
e.g.:
Set slider to 10
Search for 1
Set slider to 7
Search for 0.7 etc.
Once you've found the addresses set using the calculator
