The storms will stop rotating and fall to the ground after spawning after fiddling with settings, please help.

Hello,

Can you paste your storm settings in a reply? I can review what's happening.

There are multiple settings that influence particles. Head into the advanced settings and look for the following options:

Make sure that Cloud_ParticleSpawnDelay is equal or above 0,
make sure that all the particle effect rates are equal or above 0,
shaderParticleRateAmplifier is equal or above 0,
and that Storm_ParticleSpawnDelay is equal or above 0.

Negative numbers in any of these variables will cause the storms or clouds to stop and not show up anymore.
