Hey, team! Really excited to get my hands on this course. I realize that you're in "early release" mode, so the following may already be fixed by the time you read this, but I thought it good to send you feedback.
The intro text speaks about Intro/Presentation.tscn. In the current downloadable code, it's called ShaderPipelineIntro. Also, there's a error at line 39 of LineDrawers.gd when executing it. It's missing the will_cull property from a child node, but I'm not exactly sure at first glance where these children are so I'm not doing a great job investigating at the moment.
Hiya; The bug will be fixed in the next update and I'll update the reference in the tutorial. Thanks for pointing them out!
func do_cull() -> void: for c in get_children(): if not c is Tween and c.will_cull: c.do_cull() yield(tween, "tween_all_completed")
The bug is still in the source.
I had updated one download but not the other. This should now be fixed.
