I encountered some problems during the export process. In one version of the export, the dust cannot be seen.

When the Alpha threshold value is the largest, the layer with transparency cannot be seen, and when the value is 0, a black border will appear.

I also encountered a problem in the process of importing unity. At first I didn’t know that unity does not support gif format files. Later I found a website (https://ezgif.com/)that can convert GIF format to PNG in order, which solved the import problem smoothly.
