I’ve been playing around with particle emitters in the hopes that I can use them to add dynamics and visual interest to my scene. On my alien planet I’d like to have volcanic vents that rise up from the ground to give the scene some atmosphere. It would also interact with the air and forces can be applies during the activation of the storm.
In this particular instance the particles increase size over time. A ‘Radius Scale’ ramp is used to control this which helps to achieve the effect that the smoke is dissipating over time. This scale is also randomised to a small extent to reduce repetition.
I’ve also applied a “Volume Axis” field which applies turbulence to the particles as they enter the field. I’m not entirely sure what the difference between a volume axis field and an air or turbulence field is but it seems to do the job.
I will use something like this field that can be tweaked along with the storm controls.
