I guess there will be another mechanism (similar to SC/HJ) to initiate the landing because the game needs to create the 'planet instance'.
Tbh i don't expect a natural and seamless transition e.g. approaching the planet from space in normal cruise mode with your thrusters then dive into the atmosphere with clouds and move through the cloud layers towards the surface.
Maybe its done similar to approaching a station in SC: you target the planet in normal cruise mode and once you are within a certain speed/distance frame you have to press the 'landing' key which puts you (after some delay...) directly into the clouds and from that you move down to the surface to find ... what?
Another instance transtion to land on the surface on a RNG landing platform?
Please no...
I guess you do not realise that the Cobra engine has no problem with seamless transitions, It already works, there is just no level of detail made for planets YET.
You have to understand, the reason we actually have to drop out of "supercruise" into an instance is Purely for bandwidth and networking protocol, Not because of limitations of the engine.
There Will be seamless transition but it will be purely IN supercruise mode, You fly down to the planet whilst in supercruise, you're ship will then be able to travel BELOW the minimum speed of 30 kilometers per second, In fact the space shuttle on re-entry to our planet is about 6.6 kilometers per second! or 24 thousand kilometers per hour. So it makes sense to keep on supercruising, We should thus be able to fly around planets at hypersonic speeds (up to mach 24) the balancing factor is if you go too fast you will burn up. Once you have picked a spot where you want to exit supercuise mode you then "drop out" into the networking island just like we do now, except you will only be limited to the max speeds we have now.
There should be full supersonic effects relative to atmospheric composition, temperature and pressure.
Flying through the clouds and experiencing the thunderstorms as flashes of lighting bolts pass by, with that "in the clouds feeling"
Just thinking about this makes me extremely excited about how it will be on the oculus rift to be honest, if FDEV pull this off as intended it will truly be a gaming masterpiece.
For those who think this is impossible and will not be as delivered then just look at the odds and run the numbers, 10 people at hello games are already working with similar technology, "No man's sky" will be doing the exact same thing, though not on a realistic scale, but because of the nature of procedural generation and the smart use of level of detail systems, It really doesn't matter, Besides, we got the PC! we're not dumbing down the capabilities and technology to suit the minimum specs of consoles anyway.
