Hi Adam, thanks for your reply – I can’t seem to get anything to work using the preset!
I’ve attached a screenshot.
I added the preset to the scene, added the Conveyer Spline to the “Spline” field. Also added Particle Group “All” to the Particle Group field. And despite a lot of playing around, on different scenes with different variations, I can’t even get thinking particles to emit! Nothing happens at all.
Have I missed something obvious? I’ve looked on Tutorials and they just seem to add it to the scene and it works!
