The #declare is not really necessary (even though the author of the bubbles code
suggests it.) You can instead just place this in your scene:
mBubbleGenerator(0,0.9,0,0,6.5,0,2.4,2.7,0.0005,0.0006,70,bblTexture)
.... with no object{...} wrapper. This is because, inside the bubble #macro, the
bubbles are in a union{...}. So the macro itself is like an already- #declared
'object', waiting to be used. (However, if you want to translate or scale the
bubbles in your scene, then an object wrapper would be necessary.)
I had not worked with this macro before; it's very interesting and produces a
nice result. But the two values fBblHeightRngS and fBblHeightRngE seem to be
somewhat non-intuitive.
