That wasn’t the case unfortunately. I’m afraid I have now accidently completly deleted the driver and even saved it. I don’t know anything about drivers so I don’t know how to fix that. I tried appending in the barrel from the original start file so I would have the driver back, but now I’m missing all the parenting that was in place. Maybe I should just restart the whole exercise and see if the same problem occurs. Takes a bit more time but fixing mistake on mistake is just making the mess bigger.
Just out of curiousity, is there any course that explains what these driver things are?
