Alpha does reflect light on planes

[GreyRose]

Hi there!

I don’t know how to make completely invisible alpha channel on planes. Right now it is transparent, but it does reflect the light which is completely unusable for me. Any thoughts how to do this? I bet its easy but I have no clue, I work on cycles. I was trying to find it on the net but its so hard to even say what I mean in few words.

thanks!

Can you share a screenshot of it? Alternatively, you can try a node setup like this:

Hope that helps!
