Animation causing game object to disappear(gear vr)

Hey all,

Made a simple animation on a character via unity animator. The animation is simply a path for a guard to patrol on. It works fine when im just tweening between positions but as soon as I add rotation to the animation, my guard never shows up. he simply disappears.

This doesnt happen via game scene play mode in unity editor, only when i run the game on the gear vr.

please help.

anyone else seen this? its hard to debug when i only see the issue when i plug it into the gear vr.

 

I'm having the same problem: I've been testing animations on various simple objects and some work and some disappear.

animating scale and bouncing physics are fine.

animating transforms causes the object to disappear. I'm also trying to animate transforms on the camera, but they don't have any effect in vr. everything works in unity though.

 

update. somehow got the transforms to animate.

I used the OVR camera from oculus utilities and now I can animate the camera.

only problem is that an object with rotation disappears.

 

I also am having the issue described above. I have a scene with several gameobjects. One of the GameObjects has animation that includes rotation, and although it is visible in the unity game window when I hit play, the GameObject does not appear in the GearVR headset (after building an .apk and pushing it to my Note 5.) The scene as viewed through the GearVR does successfully show other moving GameObjects, such as POV changed using OVRPlayerController and gamepad, speedtrees responding to windzones, and grass moving with terrain wind.

 

Same issue:

I use the OVRCameraRig. Its a child of an animated object and once its build to the Galaxy S6, the screen goes black. When I un-parent it, the camera works again, but the animated object is still invisible/hidden. In the Unity-editor everything works great, but not on the S6.

Is really strange! If I find a solution, Ill let you know.

 

Ok, I fixed it by removing the Animator component and switching back to legacy Animation. I was able to convert the animationclip to legacy by switching to debug mode in the Inspector. Its a crappy solution, but it works for me....

Goodluck all.

 

i ended up just using leantween isntead of unity's animation system and was able to get around it. thanks for the replies !

 

Anyone submitted bug report on this?

 

I've made a thread on the oculus forums and sent them a demo

No update yet according to their community manager

 

I submitted this bug yesterday.

Is caused by any rotation animation on the object. You can reproduce it easily by adding an object to a scene and animating some rotation. Build it to an Android device and it disappears. Wasted ages on this one! Am on 5.3.1p1. Had it on a UI element previously too, and logged that separately, but am guessing they're related.

 

Could this be related to the same issue?

I am having an issue with a sort of slash attack that I put on the ovr controller.

Thanks,
HK

 

Wow, I wasn't the only one having this issue.
I use Google Cardboard SDK, and I too have the vanishing animated gameobject issue. Look forward to see the solution soon!

Hey, I tried to use the Legacy Animation component, but it seems to have an error. An animation won't rewind...

Thank god I wasn't alone. Having the same problem with Unity 5.3 and iOS. Seems like animations with rotation created in earlier versions of Unity still work though.

Switching to Quaternion interpolation fixes it if you can live with that.

However, that is not optimal when rotations exceed 180 degrees...

 

Looks like this bug is still present in the 5.3.1p3.
Can anybody else confirm please?

Quaternion interpolation helps.
Best.

The patch definitely helps but does not completely fix the problem. i can still reproduce it in some instances. i will make another video demonstrating this soon

 

The patch didn't fix the problem. Confirmed.

 

Is this issue just getting ignored now...? can we get an update on this from any representatives?

 

I'm still waiting for the fix, too.

Hey, I modified the animation clip and now it shows on my iPhone.

------
Nope, after some work it disappeared again!

 

Thanks man, your work around has saved my day!

 

thats great!

 

Unfortunately I am still getting this problem on Android in 5.3.2 Patch 2. It is vastly improved from Patch 1 to Patch 2, but it's still not 100% fixed yet. My team has been forced to stick with Unity 5.2.3 because this animation issue is game breaking. Please fix this as soon as you can.

 

Was fixed in 5.3.3 I believe. Is certainly fine in my build now.

 

I am definitely still having trouble in 5.3.3.

It is better though. Previously i'd see this on any objects but now i only see it happen on the objects close to my player. like my game is a fps melee/sword combat game. if I move the sword fruther out so i can see the whole thing then I have no problems. but I definitely run into issues when its too close to my player. Maybe theres an issue if it is colliding with the camera or something?

 

A long shot, but it wouldn't be culling the animation as it thinks its behind the camera? I presume the animation update is set to always? I'd suspect a different problem for this case now.

 

@HKSpadez Does your Animator component's Culling mode is set to 'Always Animate'?

 

ahh. i turned it to "always animate" a long time ago but switched it back when it didnt help. but this was when it was still having the original rotation animation issue on the older version of unity. never bothered trying "always animate" with the new vers of unity. thanks guys. that was my problem.

 

I'd been having this problem too in the previous Unity build. As @ElKrullo posted, the workaround that fixed it for me was to change the Interpolation on the animation's Rotation property from the default Euler to Quaternion. And after updating to the 5.4 Beta build, the Euler animation seems to work as expected, meaning my rotating thingies aren't disappearing.

 

This bug is still very much present in 5.3.4. Culling is set to always animate and I'm still seeing what @HKSpadez has in the video above. Is there a work around for imported FBX's with animation? I don't think I have the ability to set the rotation property if I'm not creating animation inside of Unity.

 

Any update here? Solution? Driving me crazy.

 

seems this problem is still around.
Ive created alot of grass variety in 3dsmax, animated them using morphs which is the only way to export to unity without using bones, and once in unity, some grass objects appear, some dont.
I also found out that by deleting the animation componant makes your objects reappear in play mode.

also if it does have anything to do with rotation, as users have mentioned above,why is it i never rotated any of my grass morphs during the animation phase in 3dsmax, that i presume would have created this issue?
I have a funny suspician it has everythign to do with FBX exporting. FBX is horrid considering you cant export basic modifiers from max such as bend, noise etc, and i know FBX isnt always reliable, and requires you to export a few times for things to finally work.
