I am using an Alpha Map in Cycles. The masks gets me 99% of the way there, but instead of becoming completely transparent, a tiny amount of what’s supposed to be transparent is still visible.
It’s hard to notice, so I’ve drawn in an outline as well. I just want the mask to be 100% transparent, without this black outline!
In my nodes I’m using the alpha from the .png image. I tried creating a separate alpha mask in photoshop, but it had the exact same effect. I’ve tried using a .jpg instead of a .png, to no effect.
Under light paths, I’ve tried increasing the number of transparency bounces from 12 to 128, but there was no difference in the images.
I have no idea how to fix this problem, and would very much appreciate a solution.
