Cloud Volumes and latest update for trueSKY

Today we are happy to talk about a new feature for trueSKY, which is the addition of Cloud Volumes.

Cloud volumes are a new way to add clouds to your project, with a whole new level of customisation.

To add a cloud volume, right click in the cloud layer of your choice, and select “Add New Volume”. This will make this cloud layer a volume layer, and will disable the repeating skyline. A layer can have as many volumes to a layer as you like!

If you want volumes and a repeating sky, just add another Cloud Layer without volumes.



The Cloud window now plays a much more important part in the creation of clouds. Once you create a Volume, you will be able to see it as an orange circle.

There are two modes of editing in the Cloud Window – Keyframe and Volume. First, click on the keyframe you would like to edit. Next, Double click  within the cloud window to switch between the two editing modes. If there are no volumes in the keyframes layer, you will not be able to go into volume edit mode.

In Keyframe Edit mode, you can drag the whole layer by the keyframe origin, along with any volumes in that layer. This is the easiest way to move all volumes to a new location, for example if you want the volumes to move overhead.

In Volume Edit mode, you can individually move and adjust each volume in your layer. You must have a volume present to enter Volume Edit mode. To move a volume, click and drag from the volume center. You should see the update in real time as you move the volume across the cloud window.  The size of the volumes can also be altered by adjusting the upper and lower layers. Grab the right handle to adjust the upper layer of the volume, or the left handle for the lower layer. In a future update. you will be able to adjust the distance between these layers, along with choosing the initial shape. At the moment, you can adjust the layers to make many unique shaped cloud formations. These cloud volumes work just like our other clouds, so you can edit them through the keyframes, and watch as their values interpolate over time.
