Hair segmentation alpha trouble

Hi guys! Sorry that disturbing you. I play with the new hair segmentation features and render pass.
So I create some Sobel effect on hair with render pass and want that is work our of hair alpha but start just on hair.

I create render pass logic on hair and then send it to another delay for device, but its didnt work. What do i do wrong?

I had a really tough time with hair segmentation and render passes. I think it’s bugged, but maybe I just have bad luck :slight_smile:

If you can post the arprojpkg here, I can take a look and see if I can find a workaround for you
