Those standard particles don’t take light beams… they got no material… no substance. REAL smoke and fog… and dust… can be lit.
But… ohhh… ya need approximately 86 kazillion SPS particles… really tiny ones… to make good LIGHT-ABLE dust-fog-smoke.
So… yeah, just for fun… I grabbed one of @jerome’s SPS cube-o-particles… bare-bones SPS shapes… 200,000 of them… and shot 4 colored spotlights into it/them.
Yuh, yuh, yuh. My CPU fan is now heating my entire apartment! I’m thinking about attaching a popcorn “air popper” to the case vents. It sure is a “pretty” scene… pretty boggy.
Pryme8 likes them “shafts of light”… the smokey “beams”… we ALL do. Many of us want them… thru stained glass (omg)! Others want the crystal hanging in the sunny window… effect… prisms and rainbow colors.
Well forget that… not a chance, get a clue… 14 post-process render-passes per frame. heh. (Like I have a clue).
All in all, I HAD TO see what a mass of SPS particles… with spotlights shining thru them… looked like. I had to feel the pain… to experience “the grunt”.
Maybe SPS needs an “inside of a cone emitter” feature? “Uncle Jerome’s Fake Volumetric Light Beam Machine” - from the makers of SPS. “It’s an optical occlusion” heh.
