Reduce particle effect quality to improve preformance

im making a game for mobile and it’s working fine but the particle effects are causing low fps. i checked the complexity scale and the particle effects are showing red and white.

how do i lower them so that they don’t effect performance?

btw im using the starter content particle effects

here is a lot of good information: Mobile games vfx - Real Time VFX

some tips of my own: try to keep materials simple, use masked where possible, unlit, try to keep math in custom uv’s, and use LOD’s where possible.

Can you please tell me how to use the custom uv using these and how can i lower the quality or whatever it takes to optimise my game?

thank you
