You can use the BA Color Switcher.
That sprite mode has a workaround for this issue with volumes or distance 
shaders.
 
Afaik this is a mental Ray bug, not a bug in the SI sprite shader.

Subject: baVolume fog pass with sprites



hi guys, trying to render a non homogenous fog pass for a shot, that has sprite 
shader cut outs of people on particle cards

 

getting a very odd render result where the people are lighter than the 
surrounding fog!

 

anyone seen this and found a solution?

 

ideally don't want a solution that changes the RGB as the client has signed it 
off!

 

thanks

 

a
