wanglaohan Thank you for showing us the screenshot! Actually, due to the dynamic linking, depending on the network connection, you may need to wait a little while for the download link to appear. After opening the spine-godot runtime documentation page, please wait for a moment.
If the download link does not appear even after waiting for a while, you can find the spine-godot build action in the Actions section of the spine-runtimes repository and download the template from there:
