I was looking how to improve rendertime of my scene and found that changing filtering blur value of bitmaps have huge influence on rendertime. Initially blur was set to 0,01 on all maps and rendertime (10 passes) was 06m:03s, 325K rays/s, then i changed blur to 1 and got big improvement - 03m:22s, 581K rays/s. Why is so big difference?
I,m new in Corona.
