@RobH2 You're on a support network, whining about people asking for support. If developers don't know that masses are having an issue with their product then how do they know there is an issue. Don't misinterpret the peoples search for an answer as moaning. It doesn't help when a thread has 30 people saying they have an issue, then yourself contradicts them by saying "yeah it's broken, but hey just deal with it". We spend thousands of dollars a year on a product and would expect that product to work. You wouldn't buy a brand new car with the defect of a broken radio and not request it to be fixed, correct? Based on your conclusions you would just drive another car when you want to listen to music, or maybe even listen to your iPhone. No one has the expectation of a developer to fix something at a moments notice. There are websites all over the internet where people have stated that the function has been broken since version 2020, that's two new whole iterations since the function has been broken. Everyone experience on this thread I can guarantee is genuine and not misuse. The perspective match is unusable in its current form, and this has been tested in our environment on multiple machines with various hardware configurations. Every single adjustment moves all the perspective lines at the same time. If you're not experiencing the issue then kudos, you're one lucky human.
For anyone looking for an actual workaround, I use perspective match on a daily basis within my workday and have found the only workaround for myself was to install a copy of 3ds max 2019, where I set up all my perspective matched cameras. I then import these cameras into my working scenes in 3ds max 2022. Not optimal having to switch between multiple versions of the software, but the only fix I have found to date. Hopefully, 3ds max 2019 stays supported when 2023 comes out, otherwise, this fix may not be helpful too much longer.
