A single sky background is boring. Moving clouds would be the obvious solution. And they do not require 3d model support :-)
- Graphics. Difficult balance between not showing any repeating patterns and not requiring too much Video RAM.
- Scripts. Rain and lightnings. Clouds interacting with the landscape would be cool, and make for more interesting scenario design.
- The obsolete engine support for the old invisible clouds and lightnings should be removed.

Any takers?

I think layers are also good for clouds. Simply some graphics with 2 or 3 clouds on it and the rest of the image is transparent and these graphics will scroll with different speed. And this also don't need 3D support.

Dynamic! :I

But it needs real huge areas to be blitted and a lot of memory

Not necessarily: Clouds can probably be stored in a lower resolution, and a few blits shouldn't be a huge deal for GPUs.

Large, transparent, modulted blits used to be major GPU hogs. I had implemented clouds as large, upscaled objects e.g. in The Lost Messenger, but had to reduce their number a lot to make the scenario playable on slower comps.

The situation has probably improved. But then, if we introduce PixelShaders for all such blits and generally assume larger resolutions, things could get worse again.

Hm... i made something like this in RdW-Re with particles. It looks nice but eats some performance, too.

Imo not really nice. Big unperfomant grey blobs.

Then show me some better 2D Cloud effects...

The problem is that it is not realy possible to make it dynamic...

Why that?

They look like they woud be only some (goodlooking) sprites which are fling around. Animation will look bad cause because the cloud can only change its whole look bot not of parts of it but real clouds normaly change their look instantly... and this is not really possible with these static cloud graphics.

Of course. It is not one giant animated cloud. But I think one could still make quite a nice effect just with small sprites

I think it could create a nice effect if the actual cloud objects were invisible but would spawn a couple of attached cloud particles in different sizes around them which would gradually fade out and be replaced by other cloud particles (fading in).

If we made a 3D cloud modell (rendered) which grows in...20 pictures? - and we mix it with three cloud modells we are fine dynamic. Much better than CPU-sucking particle clouds.

So, are you up for the task or what?

I find the clouds of sid meiers pirates nice too http://www.mhvt.net/quicktime/eng/graphics/pc_games/sid_meier_pirates.jpg
They are just some big cloud sprites in different shapes - like your clouds. That they don't change their shape is not so striking.

2D Sprites or realtime model?

You mean the game? They are sprites. See http://www.youtube.com/watch?v=Zc6CxTE9IuM
