hello,

i'm very surprised! i didn't know it was possible to create clouds in THEA.

nice try.

do you use medium material or something like that?

:wave:

george_drakakis · **Posted:** Wed Apr 18, 2012 8:04 am

yes, i've used medium and displacement only in the material properties.
i wanted to see how medium behaves within a mesh, and displacement was useful to create depth
and observe the results. (<- they are view dependant)
this is the scene file.

interesting i had a go but it was just taking sooo long, to many polys i think in the model, the file was 300 meg just for one cloud, i shall go back to the drawing board, and try a different way to get detail and scale,
how did you get so much detail in the smoke rings?? just displacement ?

hi christrapeze,
i think that displacement has to do with the overall scale of the "cloud" object.
if the cloud is too big the scale of the displacement texture should be big enough too, else if the camera is set far enough from the cloud formations, the results won't be visible.
i'll do some testing about that.t
the smoke rings are displaced torus objects.
this is the file that should be merged into the cornellbox examples scene.

if you set physical sky on, you will get something like this:

edit: setting "normal smoothing" off in displacement settings, will look much better
this is an example of absorption & scattering values set to 1

this is a wall light fixture, a small scale project modelled with a couple of reference images.
