Quote from: elscorpio on March 22, 2010, 05:24:11 PMThanks for the replyThe Blending shader's (power fractal) roughness is 0the density fractals roughness is 1.25If it's coming from the density fractal then why isn't it appearing in the density fractal previewalso the cumulus layer's Coverage is -0.3Basicly what i am expecting is for the cumulus layer to be more controlled by the powerfractal and the density fractal. So that clouds would only appear where the power fractal is NOT black. and the the density fractal would only work within the areas specified by the powerfractal. This is all to gain more control over where the clouds are and also how they look internally via the density fractal.maybe i misunderstand the workings of terragen, maybe it should be set up in another way.
QuoteBy default there isn't very much contrast in a powerfractal. So if you set roughness to 0 and keep contrast at ~1 then you might not get the result you expect because the powerfractal's colors are not "bright" enough. If you increase the contrast to around 4 for example then you'll see that the coverage increases a lot and more accordingly to your blending powerfractal.
QuoteA color unclamped colour adjust with black point to ~0.1 and gamma reduced to <0.5 may also aid in reducing roughness.
QuoteYou said the cumulus coverage is -0.3? Or the color offset in the density fractal is -0.3?
QuoteI found that i can control the clumping amount within the cloud by changing the lead-in scale of the density shader
QuoteHow did that work for you? Decreasing it gives more clumps/noise or the other way around?
