The problem has been solved!!! I mainly study programming, and my boss wants me to expand my abilities. I am not very familiar with Spine yet, which is a sad experience from programmers T_T. Thank you very much for your answer.

Um....... I tried it and the result seems to be still incorrect. It should be the problem with my steps. Could you please provide a GIF or video so that I can know the specific operation? Thank you

The email has been sent，thank you very much

It's the same situation, deformation occurred, but the reason is unknown

Hello, there is a very outrageous issue here. Animation can be used normally in Spine3.6, but there will be problems in Spine3.8. Import the 3.6JSON file into Spine3.6, and the result is shown in the figure

After importing the image, the result is as follows

When I opened this 3.6JOSN file with spine3.8, the result is shown in the figure (spine4.1 is also the same situation)
After importing the image, the result is as shown in the figure

You can see that the dragon's tail and body has deformed, what's the reason for this?

That's so detailed, I'll give it a try, thanks

Hello, how can I process the atlas files in batches, the texture unpacker needs to process them one by one, which is time-consuming, so is there any way to batch process them, thank you very much

I understand, it's the function of the "Canvas Redenrer" component, which can remove the transparent UI. If an animation effect is relatively transparent and "cull transparent mesh" is in effect, the animation will not be displayed, when I disable "cull transparent mesh", the animation can be displayed normally.

Nate Thank you for your suggestion, I will try it after I solve this problem

Harald For example, I have two spine animations of version 3.6, the first animation is converted to version 3.8, and "Cull Transparent Mesh" does not need to be disabled, it can be displayed in unity.
The second animation, after conversion to version 3.8, needs to be disabled "Cull Transparent Mesh" to be able to display.
Does this situation have something to do with the content of the animation?
The content of the first animation is relatively rich: a person falls from top to bottom, with special effects during the falling process.
The second animation has less content: a button glow effect

Wow, it's solved, thank you so much
There is another problem, that is, there are other resources that also perform the above operations, 3.6-->3.8, some do not need to close the "Cull Transparent Mesh" component, it can run normally, and some need to be closed" Cull Transparent Mesh" component
I found that the resources that cannot be run seem to be small, such as the special effects on a button, and the resources that can be run directly are relatively large, such as the action special effects of characters. What is the reason for this?

Hello, I met a problem, I have a 3.6 spine animation here, and then I open it with spine3.8, and export it as a josn file(include PNG, atlas), but the animation is not displayed in unity2020.3

The exported Spine3.8 animation can run normally in spine, and can also be previewed in unity, but it cannot be displayed at runtime
how can i solve this problem, Thanks!
