PBR transparent rays question (H13) Feb. 3, 2015, 7:21 a.m.

Hi,

1. With Stochastic transparency optimization turned on. Is it possible to set the number of transparent rays per pixel ?

2. Stochastic transparency turned off : Opacity sample image plane is showing 0 samples per pixel. Why is that ?


Thanks !

Its due to supported local variables by delete sop.
You could use $N ( supported local var that is one less than total number of points or prims ) in the pattern field
or use either of the following in expression field
$PT==$N
or
$PT==$NPT-1
