They're the same now - there's an interface to generate a cloud from Nasal
which is what I'm using, whereas Basic Weather uses and xml format for layer
declaration, but for rendering purp

Yes, they're completely opaque. That's tracer.frag - if it gets a white
gl_Color from the vertex shader, it's a real cloud and the fragment is dropped,
if it gets any othe

One possible optimization for the cloud rendering would be to use
polygons that closely follow the outline of the sprite instead of
quads; this saves on fill costs.
Also, I'm p
