Need to document the composition properties of AerialPerspectiveEffect.

Hi, is this for writing the story/demo of clouds effects using Vanilla JS without React, right?

[shotamatsuda]

Hello! Yes, this is for that. Sorry for the brief description.

[jeantimex]

Thanks! I’m really looking forward to seeing it! When do you think we can see it? :)

[shotamatsuda]

Maybe this weekend? Sorry, I’m not entirely sure. If it’s urgent and can share some details, I can prioritize it.

Added a basic story for the clouds: fe94d16
Hopefully this provides some ideas on how the clouds effect should be setup.
