TU and dandelO both suggested I use the cirrus layer as a blend shader for a Cumulus layer. Heres a couple of very quickly set up renders following up on the idea
Interesting results and I think I'll play further. The first is the Cirrus layer (from
Cirrus 3) plugged directly into a cumulus layer and in the second its used as a blend shader for a Perlin Billows Cloud fractal. Going to try some renders from above next ... getting some ideas
enjoy and C&C (but do note this is just trying stuff out
)
