Sub-object level animations not working after max file re-open

mcarnoss — Thu, 23 Jul 2020 05:18:46 GMT

Hi,

When animating Edit Poly's vertices, their animation is no longer working, after I close max scene and open it again later.

My own workaround for this is to select all vertices and move them a bit, then it somehow automatically restores vertices original animation. But it doesn't always work and it's pretty inconvenient to do it all the times I re-open my scene.

And this an issue “introduced” in 3ds Max 2021 or 2021.1, since I came straight from 2020.3 to 2021.1. I’ve never had any similar problems with previous max versions.

Hi @mcarnoss

sorry to read you are having this issue.
I tried vertex animation on editable poly base object and editPoly modifier, saved and reloaded scene in both 2021 and 2021.1 and animation loaded in both cases.

I must be missing something to reproduce. I used simple box converted to editable poly, animated some verts, saved, re-opened the scene, playback and anim is there, also closed and restarted max, re-opened the scene, and verts anim is there. I am not able to reproduce currently.

Are you having this issue consistently or is it in certain specific case ?
Would it be possible to provide a scene you have that reproduces the issue ?

Regards,

Thanks for your reply!

I did a simple new test scene in a max 2021.1:

- Created two boxes, one I converted to Edit Poly, other one I added Edit Poly modifier.

- I then animated both objects vertices to move slightly.

- Then saved+closed scene, and after opening the scene, only converted Edit Poly object is still animated.

The one with Edit Poly modifier has black key icons in the trackbar, but no vertices are moving.

When I then move the vertices in there, vertices jump to where they are supposed to be when animated and it working properly again.

Really weird issue.

ho! Thanks! Got it now!

Yes! a bug! Sorry for that!

I was trying both separately, and did not repro, I reproduced using the steps you gave me, both in the same scene and I got it in 2021.1.

I am trying to get the same in 2021.0 but I did not yet reproduce

Good to hear, I hope it get's fixed soon!

Any idea, will it be fixed by the 2021.2 update or will there be some sort of hotfix? Or maybe some simpler/quicker workaround for a time being?

This also leads me to ask, is it possible to somehow collapse edit poly modifier and retain vertices animation to the now collapsed edit poly object?

I cannot say if it will or not be fix for an up coming update. What I can say is that I will mention it up!

Sorry, I don't have any workaround for that, nothing better then the one you provided 😞

Collapsing the modifier would not keep the modifier animation 😞

I'm having the same issue

After I re open the scene, the vertex doesn't move.

I was able to bring the animation back by re selecting the vertices and reproducing some of the animation steps with key frames. Then the software "remembered" the animation until the next restart
