I've made a space dust particle effect that needs to spawn and despawn particles pretty fast to work (shows the player how they're moving in space) so naturally I'm trying to optimise it as much as I can.
I'm trying to get point sprites to work, but as soon as I check to enable them this error message appears:
I can't find any documentation on how to get them working, so I don't quite know what to do. Any help anyone?
Thanks in advanced
