Ack. I messed up when I pasted that, and left the last character off of the
file. Here is the correct version.
Also, to use it, you need to add
}//
just before the #if statements in all the lines like:
object { smokepuff_dot_dat matrix
<1-SW/6,0,0,0,1,0,0,0,1-SW/6,SW/2,0,SW/2> matrix
<0,0,1,0,1,0,-1,0,0,67,-61,-55> #if (version >= 3.1) material #else texture
#end { Color0 } }
So they end up like
object { smokepuff_dot_dat matrix
<1-SW/6,0,0,0,1,0,0,0,1-SW/6,SW/2,0,SW/2> matrix
<0,0,1,0,1,0,-1,0,0,67,-61,-55>}// #if (version >= 3.1) material #else texture
#end { Color0 } }
ARG! And now I see that it also has a problem with the envelope of the smoke
showing up. Well, this is a work in progress.

| Here is my improved smoke effect. I figured out a hack to get around having to hand edit anything. This is just be drag-and-drop. You can still see the spherical envelope of the smoke, but it isn't too bad. It takes a long time to render. For an (...) (24 years ago, 30-Dec-00, to lugnet.cad)

| Here is the file I am experimenting with. At the end of your POV file, you will need to hand edit a little: Make every puff line like this: object { smokepuff_dot_dat matrix <1-SW/6,0,0,0,1,0,0,.../2,0,SW/2> matrix <1,0,0,0,1,0,0,0,1,-...,-16,-113> (...) (24 years ago, 30-Dec-00, to lugnet.cad)
