Nice trick, Steven ! But personally i prefer not to convert the procedural shader to an image map, instead i build my skydomes the "old way" with a big sphere on which i apply a procedural shader . It allows to animate the sky and it saves RAM too . Here's how i set up my skydomes environments : - new scene - insert an infinite plane . This will be the ground . - insert a sphere - open the Properties tray - disable the Casts Shadows checkbox - click on the clap icon to get to the Motion/Transform tab - set the dimensions of the sphere to something around 1000 x 1000 x 500 inches - set the X,Y and Z centers of the sphere to 0 Then i create my procedural shader : zero in every channel except the Glow channel where i put my clouds . The shader i've used here will be included in my upcoming shader pack called "Lots of Shaders!" . To be released soon ... if nothing comes in the way ;) litst -----> http://www.chez.com/litst
