Hi, I'm using Unity and I want to export my Spine 2D animations at 50% of their original size to improve performance.
What's the correct way to do that? I tried setting the scale to 0.5 in the [Texture Packer Settings] under Output, but the size remained the same in Unity. Should I also adjust the Max Width and Height?
Thank you!
To reduce the size of your Spine 2D animations for better performance in Unity, you can follow these steps:
Adjust the Texture Packer Settings: Set the scale to 0.5 in the Texture Packer settings under Output. This will reduce the size of the texture atlas.
Adjust the SkeletonDataAsset Scale: In Unity, you need to ensure that the scale of the SkeletonDataAsset matches the scale you used in the Texture Packer. For example, if you set the scale to 0.5 in the Texture Packer, you should also set the SkeletonDataAsset scale to 0.5.
Max Width and Height: Adjusting the Max Width and Height in the Texture Packer settings can help fit more images into a single atlas page, but it won't directly affect the scale of the skeleton. Ensure that the Max Width and Height are appropriate for your needs.
Here is a step-by-step guide:
In Spine:
In Unity:
SkeletonDataAsset.Scale property to 0.5.This ensures that both the texture atlas and the skeleton data are scaled consistently, resulting in the desired reduction in size.
For more detailed information, you can refer to the following resources:
By following these steps, you should be able to reduce the size of your Spine animations effectively for better performance in Unity.
Thanks, Bot. I just found out that in the Skeleton Data Asset inspector, my SkeletonData's scale is already set to 0.01. For reference, I'm also using Adventure Creator and followed this instruction (https://adventure-creator.fandom.com/wiki/Spine_Integration) to integrate Spine 2D. Is having the scale set to 0.01 okay?
Also, is there any documentation on the overall performance when using Spine 2D? I found this post (https://en.esotericsoftware.com/forum/d/12325-optimization-spine2d-in-unity/3) , but it seems like the thread it mentions has been removed.
Thanks!
The scale of 0.01 is typical and depends on your game world units. Units in the Spine editor are often treated as pixels. If a game world is in meters, the pixel-based units need to be scaled down a lot.

If 0.01 is your normal (100%) scale and you want your skeleton half (50%) the size, you'd use 0.01 * 50% = 0.005.
The discussion you linked has a broken link for some reason, but the thread it mentions is here:

acai I just found out that in the Skeleton Data Asset inspector, my SkeletonData's scale is already set to 0.01.
The Scale parameter 0.01 of SkeletonDataAsset has nothing to do with texture resolution or performance, it just scales the skeleton larger or smaller, similar to what the Transform Scale would do.
If you want to reduce the texture resolution, either use Texture Packer Settings or in Unity you can use normal means of setting Max Size for each target platform at each Texture asset, or even use Quality settings to use half or quarter texture resolution for everything.
Thank you!
