@Thalatta come on... The reason you had to build it to test it, it's because it changes the engine (like 90%+ of the change of this PR are engine improvements).

I don't know how things work exactly, but would have expected that at some point things like these would be added to the community mod (or whatever) for more people to test (since not many build), for then to go through review to be added to the next release? Or maybe I swapped the order of things in the middle.

There is no IP on anything here so you can do whatever you want.  Just note that this is not merged yet so we don't know for certain when it will be part of the game. It is tested (thanks to those who did!) and ready for next release but the timeline is tight so it really depends on if someone awesome pick it up for review.

What a blessing to be able to see those mechanics.  Can I upload this to TikTok?

Thanks - but really no rush please!
