Description

« Hide

(Note from Celierra Darling: the patch that is attached above is for the source code, not for the 'binaries' that most people download and install from the official website . The patch is mostly for Linden Labs or other programmers to inspect, apply, and test (though some people may have released versions of the view with this patch in place). Being "Fixed internally" and "Resolved" at the same time means that the fix is probably ready and is awaiting release to the public, usually in the next version of the Second Life viewer. Even though the issue might not be resolved yet for users, the issue should stay like this, as there is not much that can be done until the new version is released.)

When i move the mouse, the avatar head follows the movement as expected.
When i keep the mouse still, the avatar used to turn back its head after about
4 to 5 seconds. The turnback to looking straight forward was rendered in a smooth transition.

Since today with the newest SL viewer 1.17.0 (12) the head movement has turned into an ugly
jumpy animation. It still follows the mouse cursor in the expected way. But when the head turns
back to look straight forward, it no longer does a smooth transition, but jumps instantly to its end position.

This behaviour is very unpleasant. As i am doing machinima movies, this behaviour destroys avatar movement
quality significantly.

This same issue affects emote HUDs that play the same animation repeatedly. Instead of nearly seamless transitions between each play of the animation, the face of the avatar oscillates quickly between states.

[Edit by Marine Kelley]
I have raised the Priority to Critical because it badly affects a lot of content creators, in different disciplines. That way it matches the one of the issue ~~SVC-318~~ (even though it's Viewer-related as far as I can tell).

Confirmed. Perhaps, related to the cross eyed bug that came with 1.17 too.

Steps to reproduce:

1. Use your mouse to hover (not alt click) on something nearby or on your HUD.
2. Observe head follows mouse as it should
3. Observe head "snapping back" to center position with quick jerk movement

Expected behavior: Head should smoothly follow mouse without snapping back

This is reproducible both with default stands and AOs that allow for the head to move freely.

More generalized 100% reproducible case:

1. Press escape several times to reset your camera to "default".
2. Use your mouse to hover (not alt click) on something nearby or on your HUD.
3. Observe head follows mouse as it should
4. Don't move your mouse for 4-5 seconds
5. Observe head "snapping back" to center position with quick jerk movement

Step 1 is necessary if you were alt-zoom focusing on anything.

This is annoying! Don't even have to try to reproduce this one.

Does anyone think this bug relating to the facial expressions popping is related? https://jira.secondlife.com/browse/SVC-318

On the off chance this helps: I'm observing this on the Mac client as well, OS 10.4.9 on a MacBook Pro, Intel Core 2 duo at 2.3 GHz, 3GB RAM, ATI Radeon X1600 with 256MB VRAM.

I've noticed that turning AO off accentuates the problem significantly, and using animations that brutally seize control of most of the joints (head included) tend to mask it, near as I can tell.

Confirmed here too, though I don't think it's related to https://jira.secondlife.com/browse/SVC-318 because the head movement is not an animation (in that it does not use pre-calculated rotation values but smoothly follows the mouse) but more of a viewer problem. Random guess here though. It is annoying to say the least.

Voted.

Gigs Taggart added a comment - 16/Jun/07 06:11 PM

This patch fixes both this and ~~SVC-318~~ which is just a different manifestation of the same bug.

Someone refactored the deactivateMotion code, such that it set the motion weight to zero. Apparently it was being called in some places where it really shouldn't have been called, which was causing motions to end suddenly rather than go through the normal "fade-out" code. This patch removes a key call to deactivateMotion that seems to be causing the symptoms at hand. Calling it at this point is unnecessary, as it will get called later from other functions.

my last patch caused some new issues, this one is a lot simpler and just rolls back the bug-inducing changes.

It's really important we get this fixed soon, thanks for the patch, Gigs.

Watch for progress, Soft Linden is investigating received repros too.

actually this bug is the reason I might delete my second life account if it is not fixed very very soon. Looking at my avatar makes me puke.
Btw when I sit in a round with other avatars, why do I see only my avatar behave in that strange way.

I am still having this problem. And for some reason cannot download the patch. Any assistance you can offer would be greatly appreciated. Thank you .

Gillian Waldman added a comment - 20/Jun/07 08:37 PM

cherie - patches will be applied by Linden Lab when the patches are tested and verified for the next update. Alternatively, you can apply the patch to your own code using your own compiled version. My recommendation would be to wait until they roll out an update.

I think I'm going to add a brief note to the top of the desc about the patch and 'fixed internally' resolution status.

Eyes still crossing. Was able to reproduce when opening my own profile... also when on pose stand. Have asked others who say that they are having this problem, as well as head twitching, though have not been able to reproduce that yet.

Thanks Celierra!

So we've got the top and bottom covered...

IMPORTANT: Each and everyone, please pay attention to the Fixed Internally status that this issue was previously correctly displaying, which I'll re-do.

Please don't reopen issues without understanding this better or at least asking to learn more, it wastes everyone's time. Thanks!

Beautifully covered Celierra, thank you so much for making all the "IT Talk" into English for us newbies

Looking forward to the next patch now, hope it's soon!
