v0.21.0 introduces a few nice changes:
Improved lighting and post-processingImproved wall cloud renderingChemical polarisation: you can polarise chemicals to have the opposite effect to normal, so you can now also weaken tornadoes, shrink tornadoes, make the paths *more* unstable (useful if it's heading towards a town) and increase the ground speedThis is a pretty big visual overhaul, as always I'm looking for feedback and hope you enjoy the new update! :)
