I'm using LW 7.5 and am experiencing some problems when rendering shadow passes using the Render Buffer Export plugin.
I want simple white shadows on black geometry, but I'm getting surface colours and other anomilies.
Does anyone know where I can find some notes on how to set this up correctly??

It seems to work correctly in V8.2 using the "Shadow" buffer type and exporting to TGA-24 format (actually produces 8-bit greyscale images). I can't test V7.5, though.

You might try TGA-24 output format if you're not already, or some other format. It might be an anomoly in the specific image saver you're using.

Yes, I am already using TGA-24 and 'shadow' buffer type.
I have also tried using a similiar but different plugin (Buffer Saver) and have had a similiar issue. I'm obviously doing something wrong...
I still get shades of mid-grey in the shadows, I thought a shadow pass was supposed to be defined by clear black or white areas - an 8 bit image as you suggest.
I've attached 2 files showing the WRONG result I get and the RIGHT result I think I should be getting.

Thankyou for the reply anyway.
