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
I haven't really been following this thread closely... are the
"tracers" basically occludes? Are they completely opaque?
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
I've managed to get a test implementation for the idea of filling the depth
buffer early by clouds by inserting tracers into some of the cloud calls. The
tracers are in essence just opaque white sheets marked with a top shade factor
of 0.0 (black - no real cloud can ever have that low a value)
