Cycles / BI painterly material - possible ?

I am looking into modeling a cloud and applying material with SSS to it so it would end up looking like this:


Has anyone tried making painterly materials in Cycles or BI ? Could you please advise on how to achieve such look ? (It can’t be done using Freestyle because I need to render panorama and Freestyle doesn’t seem work with panoramic rendering)

Thanks.

have you try to paint your own clouds on a sphere then bake it as an HDRI map?

I am not a great 2D artist, so I am going after 3D. Painting on a sphere is not easy anyway, plus it will create distortion.

paint in 3D is not easy !

i’v seen a lot of nice free clouds HDRI

but why do you want to paint your own HDRI map!

All available clouds are photographs, not painted at all but rather made with DSLR and chrome ball. I did 't say I need HDRI map. I need to model clouds, have painterly materials, render panorama and convert it into skybox for my game.

So I got this basic quick cloud with super basic material:


How do I make “highlight” stronger?

How do I add more steps, so to speak, to shading (5 to 8 probably, judging by the original image) ?

How do I add rim lighting?

How do I add SSS ?

How do I make gradient background? (color ramp somehow rotated 90 deg. I suspect)

Thanks!
