I got this working somewhat, and managed to record a shot clip in preview mode:
However when I saved the project and restarted the editor, the positions weren’t saved and nothing worked anymore. Is this something that’s supposed to work right now? Also when I tried packaging the project, it was successful but the exploding doesn’t work at all.
Edit: Upon further investigation I noticed it’s the mesh components that are not saving, transforms are.
Edit 2: As far as I understood form studying the blueprints with my very limited experience, this isn’t a finished blueprint and it simply can’t work as the object references aren’t saved anywhere permanently. I worked around this by saving them in a string array and using that to rebuild the object reference array on load and demand. Works fine like that when packaged too.
