A simple mod adding multiple layers of clouds with configurable height, thickness, speed and direction.
By default, there are two layers of clouds:
These resemble Cumulus and Cirrus clouds.

You can add or edit existing cloud layers using the config menu (accessible with mod menu). Alternatively, edit the config file at config/cloud-layers.json.

Use the following options to change the shape of clouds:
You can also change the opacity, making clouds transparent.

You can change the speed that clouds move, and select the direction of movement.

The option Use Relative Height makes a cloud layer appear to stay fixed in the sky, regardless of how high the player goes, simulating a skybox effect.
You can add layers that only show up when it is raining.
