Title: slow RnD Multiscatter parsing with millions of instances
Post by: shiftman2012 on 2016-11-03, 05:34:40

very slow multiscatter parsing with many instances comparing to vray / 2-3 times slower
 i tested scene with 5000 000 grass instances. 25 sec corona waits for something and does nothing, parsing starts at 28 sec.
 it takes 40-50 seconds to start rendering in corona. comparing to corona scatter - it takes 10 seconds. vray starts rendering after 20-25 seconds.

 is there a way to speed up parsing using multiscatter? or it could be improved in future corona versions?
