preview with "auto guess vert tilt."

V-Ray V-Ray for 3ds Max Issues
1

Just a simple question : When you have a cam with “auto guess vert tilt.” checked and you want to “create preview animation” (Shift+v), is there a way to have the vert tilt. in this preview ?

Thanks in advance

2

Is this with the 3ds Max Physical Camera or the V-Ray one?

a VrayCam (max 2015 so no 3ds max PhysCam)

I really need to do this preview. Is there a way to solve that problem ?

Turn off the “auto guess” option in the camera, turn on the Max animation mode, go through every 20 or 50 frames of your animation and press the “Guess vert tilt” button in the camera. This will create keyframes for the vertical tilt value. Then you will be able to do the preview. A bit tedious, but it works.

Will make a note to look into why the tilt is not updated during the preview.

Hi Vlado,
Thanks for that trick !

Anyway, I have a Vraycam with target + vert tilt… I tried to render my scene (with low GI, low output size, … everything low !) last night and Ihave some problem with the tilt…
It’s like the “auto guess vert. tilt” is not updating at each frame. My cam AND my target move.

Is it the same problem ?
Do we have to avoid tilt in animation ?

Thanks,

Hi,

I come back with the same problem…I don’t care about the previz, now, my problem is my frames

I’m using a vraycam (no target) with a path contraint. I tick “auto guess vert. tilt”.
At 1st frame, my vraycam start with a rotation by default (it’s why I used vert. tilt") then a hundred frames after, my cam is fully horizontal (I don’t need anymore “auto guess vert. tilt” until the end)

So when I render my frames, it’s ok for the first but it seem like “auto guess vert. tilt” continue to correct vert. when my cam is horizontal.

Is it really possible to use the “auto guess vert. tilt” option for a animation ?

Any advice is welcome ! thanks

3ds max 2015 / Vray 3.60.04

You can use the same work-around with keying the tilt value at certain intervals during the animation. I will add your case to the JIRA issue.

Yes, thanks Vlado.

That’s what I finally did and it works great

I can live with that work-around :wink:
Thanks again
