This may be a bit of a vague thread, for which I apologise in advance, but I could do with some advice on generating large scale procedural skies and cloudscapes in cycles.
To give you some background, i’ve spen the past twelve months sorting the CGi for a short film (steampunk airships) using blender. Due to limitations on time and the processing power available, we’ve kept it fairly simple so far - procedural sky background (or image in some cases), with the clouds rendered as images and inserted on planes. This has been quite effective, but it lacks a depth and feel you see in more advanced renders. For the next short film, i’d like to get the backgrounds to a look/quality not dissimilar to this: (eye of the storm by Lovett):
But i’m struggling to do so. I’ve tried using kilbeeu’s cloud material, to no effect - all I get is jagged edges or strange anomalies, and i’m a little stumped. Does anyone have any ideas on a good way to do this, both from a materials/backgrounds point of view, and to a lesser extent, compositing?
