This is Cloud System. It can create clouds, but not very realistic..
For disambiguation, Cloud System does not create clouds (like autosaves and things). Instead it creates clouds (these unique shaped things in the sky at day)
Why choose Cloud System?
Cloud System can make moving clouds, unlike Roblox's built-in dynamic clouds, and has more customization. It can also interact realistically to players, like produce a hole in the cloud (which only produces a smoke because my coding skills limit me to doing that.)
Customization guide
Cover
How intense clouds will spawn.
MaxDensity
The maximum transparency of the clouds.
MinDensity
The minimum transparency of the clouds.
Speed
The amount of time, in seconds that determine how long the clouds will move to get to the other side of the screen.
I am trying to replicate these old Roblox cloud meshes people used a lot back in the day, procedurally, if you didn’t know already. I will add height and color variation if I can! I will try making it client sided, since players will see randomly generated clouds from each client. There is already a built-in "timescale’, which is the Speed setting.
A reason why the clouds look so ugly, is because I don’t use any complex algorithms, but just pure RNG.
Resources are not always about being the most efficient. They can be projects that someone has been working on that they want to share with others sir.
I would suggest researching procedural generation. Also this is not an “engine” so you should probably rename this to “system”, it may be misleading.
Its completely valid for people to give criticism on a post that implements a feature that already exists in Roblox that is more efficient, implemented in a better way, and looks nicer.
These clouds are single meshes. Of course looks are subjective, but to me it looks like a bunch of meshes I would pull out of the toolbox that was uploaded years ago and put them all over the sky. Giving criticism is not invalidating a resource, but it’s not wrong to object this post by saying that Roblox has just implemented this idea better, in a way that is more performant and looks more realistic.
