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/6,0,0,0,1,0,0,0,1-SW/6,SW/2,0,SW/2>
matrix <1,0,0,0,1,0,0,0,1,-46,-16,-113> } #if (version >= 3.1) material
#else texture #end { Color0 } }
Into this:
object { smokepuff_dot_dat matrix <1-SW/6,0,0,0,1,0,0,0,1-SW/6,SW/2,0,SW/2>
matrix <1,0,0,0,1,0,0,0,1,-46,-16,-113> }//#if (version >= 3.1) material
#else texture #end { Color0 } }

| This is almost awesome, but I can't quite do what I want. I made a smoke puff .dat file for POVRay. You just drag and drop smoke puffs in using the CAD program, and you can have a smoking car or a fluffy cloud for your airplane. It uses L3P's POV (...) (24 years ago, 30-Dec-00, to lugnet.cad)
