Auto vertical tilt correction viewport problems

[josephriehl]

Hi All. Not much of an introduction post, but I can't seem to find a solution for this (or if it even exists).

 

I'm having an issue with the Auto Vertical Tilt Correction enabled in the Perspective Control rollout of the Physical Camera Settings. I'm using 3DS Max 2015 SP3 and Vray 3.4

 

When I have the Auto Vertical Tilt Correction Enabled, It will switch to a 2 point perspective, then switch back to 3 point, as if it updates to 3 Point when the "progressive render quality" function kicks in. Clicking in the viewport switches it back to 2 point temporarily, then it reverts again to a 3 point perspective over and over.

 

Is this a known bug? Is there a fix? Thanks.

there is a glitch on the vertical til while working on viewport.

But for what I understand it should render fine every time.

When you say that it is changing, this is while rendering? during animation I imagine?

or it is just view port performance error?

[josephriehl]

just viewport. renders fine. Good to know... Hope they fix it soon. Thanks!

This used to be a bug when depth of field was enabled. Do you have it enabled?

3dsmax 2017 and vray 3.6. not yet resolved and got even worse:D

Separate issue, but I always found the auto tilt correct distorted the image. I now always keep the target same height as camera and use the shift function instead.

Thanks everyone. It was indeed the DoF bug. And.. yeah.. still not fixed in vray 3.6 (max 2016)

I have been facing similar issue as whenever i wanted to change some parameters of positions of the camera, the vertical correction would get distorted, and it needed to be deactivated and activated again. After breaking my head over this issue for over half a year, i somehow have come to a conclusion that this only happens if my camera in question, is hidden. Whenever the camera is visible, this problem doesnt occur. Please do let me know if others are facing similar thing.

Yes, same problem here. Solution: unchecked Depth of Field under Physical Camera

This is actually the way it´s done in architectural photography.

I find it disturbing that the so-called "tilt" has not much to do with the Tilt function of a real camera.

In real world the "tilt" feature of a lens is tilting the depth of field in reference to the image plane

Not at all, but if you keep your depth of field low you will see this effect.

Thank you! Your solution worked for me.

Still a bug in max2021. I'm wondering if Autodesk is even aware of this problem, since I couldn't find any post on that at their forums.
