331 (and counting) Professionally tuned, highly reusable, easily repaintable and tweakable Particle VFX prefabricated about all thieves!
SPLASHES, water streams, football, beaches, waterways, bridges, pipe laying, roofing SPLATS and more!
And think of all the variants you can easily make!

All prefabs are made with less resources and texture while trying to achieve the best effect, while particle count is also quite low.

Nevertheless, by simply rotating the particle emission rate, you can easily take VFX from mobile friendly to desktop usage. Out of the box, VFX is a good compromise between the two.
Most prefabs are nearly clear white or tinted to avoid creating unnecessary duplicates for each color and let you customize the property to your needs.
It is really easy to get effects like ACID, LAVA, TOXIC WASTE & FUMES, RADIOACTIVE STREAMS AND POOLS, POVPLE CLOUDS OF LOVE, POISON, VOMIT, STREAMS, CRYSTAL FUNTAINS, etc.

Well there is already! There are hundreds of prefabs including Blood Hit FX, Blood Rain and more!
