Fully procedural Cloud Shader. Blender, Cycles.
Turn cubes into unique clouds, with this simple #Cycles shader.
I recommend that you watch Bartek Skorupa talk #BCon14 first:
• Manipulate texture coordinates like a boss...
where you can find all necessary theory behind manipulating textures.
Yeah, like a boss;)
When you follow this video, you will know how to simply duplicate a cube to get unique cloud for each object.
For more complicated shapes you can simply combine cubes (keeping them as separate objects) or add more noise textures with different blending modes.
Or use a particle system (instancing a cube with randomized size, rotation etc) and still - each cloud will be unique.
And the best thing? It uses very low memory to generate really complicated cloud shapes.
