cut and paste from ver 5.3.5 release note, under improvement…
as far as i know, until now each trail render cost one draw call…
is that mean that now line and trail render will be batch → less draw calls?
more from that list (under fixes):
Android: Fixed blending with background on Unity splash screen. - yap it was ugly!
Yes - multiple lines/trails will now batch dynamically. I can’t recall if Lines/Trails ever used to batch… I guess the “reintroduction” was mainly relating to Particles, which definitely used to batch… stopped batching… and now they batch again
