3DS Max 2016/17/18 - "Create Physical Camera from View" Broken ???

[JezUK]

I've tried valiantly to make the move from 2014 to *any* newer version of 3DS Max but today wasted a big bunch of time......

I needed to do a perspective match, but Max won't do that with a Physical Camera, so I did a Perspective Match with a Free Camera, got it as aligned as I could and deleted the Free Camera (to change the viewport to a perspective view) and then used;

Views -> "Create Physical Camera from View" to create my Physical Camera 'camera matched' against my backplate.

Worked like a charm.... or so I thought......

Finished my work for the day, shut down Max, reopened the file the following day today and the camera has MOVED......

I've tried this in 2016, 2017 and 2018 and ALL of them have this problem ????

I created a video and uploaded to YouTube - https://www.youtube.com/watch?v=HUjuwlJn8Ng&

Does this work for anybody as I cannot believe something as basic as this is broken..... I mean really.....

(still waiting for an answer from Autodesk).

I believe you that it's broken.

However, why not just align the phys camera with the free cam using the align tool? (I know it's not as convenient and there still shouldn't be such an annoying bug, but the alternative is not that horrible, I don't think.)

Yea, I've had this happen to me too. Camera matching is really finicky with Max and not the most pleasant experience. I've also had a problem where the rest of the line guides move on their own when I'm adjusting one of them. No Idea why. Then I have to stop stop adjusting that one and go back to the others that got misaligned.

By the way, I think you can camera match with a Physical camera too as long as it's not targeted. So disable the Targeted checkbox after you create the camera and try again.

Alex I think Perspective Match has that weird moving axis lines problem with Physical Camera only. If you use a regular camera, I think it will behave. Then just align the Physical camera to the Regular one.

Yep, that's the solution - well, part of. I spoke with Autodesk as I hadn't twigged what exactly was the issue....

If you Perspective Match with a free camera (which is the only camera you can Perspective Match with), then when you do a "Create Physical Camera from View" you have to then uncheck 'targeted' for things to stay put.

If you "Create a Physical Camera from View" from a Targeted Camera view, then leaving your newly created Physical Camera as Targeted will be fine.

Basically, it's all got to match.
