Installation and Compilation



The Sequencer and Sequences

In trueSKY 4.1, you should make sure that the 3D Clouds, 2D Clouds, and Sky properties are the same for all sequences. Then, with cloud keyframes, make sure that any property that has horizontal extension is the same: Cloud Volume Width, Noise Scale, Worley Scale.

So for example if your 2D cloud keyframes have width 1000.0 in one sequence, they should have 1000.0 in all sequences. It doesn’t have to be exact, and some variation will be ok. But if there’s more than about 10% change over a few seconds of transition time, you’ll notice it resizing, and that will look wrong.
