Ok, I've definately created the first(I think) functional metaclouds in TG2.
[attachimg=#]
It's just a quick test but, this single cumulus cloud is actually 3 of my TG cloud objects, built together to give
complete control over cloud shape!
Use the bounding box translation arrows to push and pull your cloud objects around your sky, duplicate them some more and place as many meta clouds in your scenes as you want, specifically where you want them and, build them to specifically what SHAPES you're after.
Push-me-Pull-me clouds in TG2, wonders will never cease! See image 'metacloud workspace' to see how easy it is to move the clouds around the scene. They each have their own bounding box!
Here's a metacloud clip... Each metacloud object has its own cloud layer and density fractal, you NEED a cloud layer for each object but you DON'T need a density fractal for each one. A single fractal
could be used for all of the objects and, because of the differences in xyz translation and meta-cloud object scale, the patterns will be different, but consistent, across the whole cloud formation.
Have fun! I know I am! This is good stuff.
Oh... And, TG2 metaclouds are volumetric TG2
objects, not atmospheric shaders so you cannot use them like you would normal cloud layers. Incase anyone needs that clarifying, although I know you probably won't.
