Jee, thanks for the nice donation ! - much appreciated.
That cloudscene node demo is actually in the source code of CopperCube. I added it in after getting the source files from Irrlicht website from very old archive. Took me ages but eventually got it working as had a number of incompatability issues that had to be sorted out.
See my video about the new cloud system in CC - its exactly whats in the cloudscene node demo actually - use:
ccbGetCloudLayer(node,"tex1.png", "text2.png", true);
Use a parent node thats invisible to attach as many cloud layers as you like - cloudescenenode demo uses 3 layers and 3 different textures for that.
I will upload the 3 cloud textures into data/images of the binary zip file.
