Worth a watch to understand a basic of the tech in some areas and also what makes a little difference from some others out there with tech etc. It shows the difference of tech even if similar to other games about why it is still different and pushing what a games engine can do.
The gas cloud side for instance and how they have got that to work is certainly impressive. The idea on how they proc gen planets using humidity, temp and altitude is also clever and certainly allows for much greater design than we have with say NMS or ED.
The soft shadow elements from the terrain is for instance excellent, the weather is excellent (at least when it becomes fully dynamic) etc.
Would like them to work on how they get those humidity and temp settings by having it adjust based on distance from the equator for instance so you can have greater variation rather than it being more planetary wide as it is at moment. At moment the heat map they create means it really doesn't work like that and is more global and thus trees are all at the same range across a planet wide map currently.
The other is of course the popping of assets. It is still awful like every game out there, and they over use rocks etc across plains so it looks overly busy in my view. Like the frozen ocean texture with a million icebergs instead of a few.
In terms of the feature of FOIP and the camera thing etc, might be a little bit of a gimmick but it's been in game to some point for and was shown/stated in like August 2017 and it is a third party software they have brought in and then worked on updating it and the code and improving over time. A bug is just that though.
