packages!!!!!

Please confirm the installation by clicking yes.

Please wait while Unity downloads the package and recompiles the scripts. When done, you’ll see a Spine installation complete message — press OK to continue.

You might see a message about outdated scripts — that’s okay, we don’t use those. Simply select “Yes, just for these files” to let Unity update them.

You’ll now see “Spine is already installed” in the installation window — that means you’re good to go!
