How to optimize 2D animations (with bones) ?

Hi everyone !

On our current project, we use the 2D Animation package (it's still in preview) with Unity 2019.2.0f1. We use it to animate our enemies and our characters with bones.

But if we try to show on one scene 80+ enemies/characters, the FPS drops to something like 4 fps. When I open the Unity Profiler, the drop seems to come from

SpriteSkin.LateUpdate()

...



Is there any way to optimize our project (animations ? sprites compression ?) in order to bypass this problem ?

Thank you !

 

This is an issue introduced in 2019.2 and it’s current version of the package. The previous package under 2019.1 didn’t exhibit this. I’ve reported a bug which rustum acknowledged, hopefully it will be addressed.

 

Oh, ok !
Is there any public link for your bug report ? If there is any chance that I can follow it maybe ?

 

I’d hope any news on this front will be in the sticky thread(s) on this forum. Development on it has been pretty glacial though, so I wouldn’t expect a fix soon.

I’m just working on other things while this tool stabilizes, but I’ve been doing that for 8 months and am running out of other tasks to pursue. Pretty soon I fear I’ll be forced to abandon it.

 

Any idea on how much time it will take to get an update ? Even if it's not completely precise or accurate, just in order to give us an idea. We really don't know if we must spend time to switch to another animation system, or if we can wait for an update soon ?

 

Thanks for the assurance. I hope I didn’t sound overly grouchy, I love what this tool can already do, and if it were released and supported back in 2019.1 I’d have been satisfied with the features. It is exhausting though to watch it on this rollercoaster of performance and strange interactions with other packages and moving parts between 2019.1-2019.3.

 

hey is this problem fixed or still not

 

Hello I'm working in unity 2020.1 and still have problem. Thanks advance

 

Do we have to tweak something else or just install the package? Thank you very much in advance!

 

I feel stupid for asking, but where to find this package.json file? Do you mean I should add that line to the package.json file found in Library\PackageCache\com.unity.2d.animation@5.0.4? Where should I include the line in that file, if that's the right file?

 

Got it. Thanks for the quick reply!

 

I must say, I'm impressed with the performance increase with both packages installed. It was pretty worrying to see the animations take up to 10ms per frame before with a bunch of animated characters walking around. Lucklily, that's almost completely gone now.

It would be great if this performance increase can be made available for the broader audience, and not just the ones that manage to find this thread.
