Thanks, I have been keeping an eye on Star Citizens stuff, so helpful to have it here to keep track of it. Theres currently no reason the planetary rendering itself couldn’t be a plugin right now (The gravity is engine modifications). The 64 bit precision does not alter UE4 in any way, all the calculations for the planet surface is calculated in 64-bit precision, but then stored in 32-bit around the origin, this is why origin rebasing is used.
