For those who use Particle Illusion the long awaited Spring library is available for download. A bit of everything from nuts and bolts to pressure gauges, LOL
The pressure gauges are out there alright and I love that. I like the combination of the moving dials and the effect itself. I think you're onto something there. Maybe a kind of Steampunk effect? Retro-future FX? More inspired technology effects like these please!
