Does anyone have an algorithm or shader to create clouds at random and other than the pre-defined skybox?

There is in sure loads of resource for shaders.

Try shadertoy

And plenty on here. The DLC pack of shaders and some work by fubarpk who has got some good shader coding. Just put Shader in the search here to get some inspiration.

Or maybe use Perkin noise to do algorithmically - there is some on here on Perkin noise too.

With regret, I haven't got a laptop to do any coding myself at the moment to help further.

Good luck

Here is the clouds shader link from fubarpk (hope you don't mind fubarpk)

Hope it helps and Good luck

I bought the shader pack and sound pack and game guru for six quid using a steam code a few months ago . It is pretty good what the shader pack can do although I have yet to implement it .
I got the trio as I wanted the sound pack the others were just a bonus.

thanks guys !!
