Alright. I've had this idea for awhile. It might not have a lot of practical uses, but for what I'm working on it could be wicked cool (assuming I finish it). At this stage I'm just interested in knowing if it's possible, as whether or not it is will have a large affect the final product.
I got the idea from replaying a small portion of LoZ: Skyward Sword for inspiration.
Watch this video from 4:00 to 4:30 or look at these pictures to see what I'm getting at.
Here is a diagram that took me 3 days to put together:
Open space --> (Floating islands and other airborne things)
Cloud layer --> -----------------------------------------------------------------
Open space --> (Continents, oceans, the works)
Slate/ground --> -----------------------------------------------------------------
Ideally it would be thick enough so that you couldn't see right through it and it would look somewhat decent but not lag like hell. When it comes to the texture: playability over quality. I don't care if it's a giant white square.
As I always mention in my S&R topics: I have no idea how anything works. However, I have done a little research.
Ladios' Slate Edits has a map with a "sandstorm" effect. Maybe it's possible to have an effect like this from a certain height up to another certain height. I've also tried playing with moving cloud heights but as far as I know they're like the sun flare and can't be "in" the map.
Regardless: later on I'll be looking into relevant gameplay mechanics (players die if they hit a certain altitude without having equipped an item, some flying vehicles would stall under/above a certain altitude, stuff like that). The cloud layer would visualize these boundaries. But again, right now I'm looking for proof of concept.
Thanks for reading. Interested to see what you guys have to say.
