BEWARE: installing R23 breaks the ZBrush GoZ connection to other C4D installs.
I am still using R19 (even though I own R20 and R21) because I do a lot of ZBrush sculpting for my work and GoZ doesn’t work with R20 onwards.
R22 and R23 have a new GoZ functionality so I thought I’d test R23 with the 2 week trial period. Whenever I pressed GoZ from ZBrush it would start R23. I would make sure the path to C4D in ZBrush is R19, which I use for all my work, but R23 must have done something to the GoZ files which forced all GoZ exports from Zbrush to go to R23.
Annoying but I worked around this during the trial period. That trial finished and so I uninstalled R23 buuuuuutttt . . . GoZ was not working at all now. I checked the path to C4D and made sure it was to my R19 install. I ended up grabbing the GoZ folder from another machine and pasted that into my main machine and that fixed it. BUT it was a completely unnecessary waste of my time.
So if you use ZBrush and C4D don’t upgrade until you are ready to commit to R23 all the way as C4D will break the GoZ connection.
It is really annoying how long C4D took to fix the GoZ connection and now that ‘fix’ is messing with me.
