Instructions: Feel free to use, no need to ask. Credit is appreciated but not required! Backpack the clouds sprite, not the example! Scroll to the bottom to see how to use clones. Feel free to advertise! Looks better on TurboWarp with HQ pen enabled. https://turbowarp.org/1362831302?hqpen Variance% is how many parts of the clouds are a different shade. Variance is how much the shade of the parts of the clouds change. Performance: It should be more than enough for whatever game you're making, whether it supports mobile or not. It hits the FPS limit on both pc and mobile. I haven't tested it with turbo mode (removes 30 FPS cap) on mobile, but on my laptop, on Scratch, it fluctuates between the high 900s and high 1500s. It's pretty similar on TurboWarp. I have been doing nothing with this project except for optimizing it since I made it. There may be more optimizations in the future, but probably not. It's very challenging to think of ways to make it run any faster. How to use clones: In the clouds sprite, include this code: when I start as a clone Generate set render? to 1 In the stage, include this code: when flag clicked forever erase all broadcast Render Clouds
