Volume Shader as Clouds
Posted: Sat Nov 13, 2021 11:32 am
Good day, I've been working on a render for planet Earth. I used a octane fog volume to generate the atmosphere, and a sphere with a cloud map texture for the clouds, but someone suggested I use a volume for the clouds instead of just a sphere with a material. I attempted to use an 8k cloud map texture from NASA blue marble into the texture field in the generate tab of the fog volume shader, but whenever I render the look is very poor and looks warped. It seems to function well enough with a noise shader through Cinema 4D's built in feature.
The first example sphere is with a basic built in noise shader, which shows it functioning. The second is with the nasa cloud map.
Though my settings in the example reflect no render multiplier and a low voxel count, my settings at render time were approx 3cm for Voxel Grid and 10 max for the multiplier which should be more than enough to provide quality? My computer begins to chug going any lower much past this number.
Any help is appreciated!
