clouds above sky 3D model

this is a selection of clouds that you can use as a template in your scenes, both as a sky or as the main element of your scene. as far as i know, it can only be rendered with the maya software render and only be used in maya. vray and arnold definitely do not work (as far as i am concerned). there is a maya binary and an ascii file. it can also be duplicated to transform an even greater amount of clouds. it renders quite fast too, so if you have to do multiple render passes with different render engines, rendering the clouds seperately will definitely not take lots if time.
