How to stop hair showing in reflective material?
I have tried everything. All I want is to render some grass (hair) that does not have a reflection in the water-like material right below it. The compositing tag does not seem to have an effect, no matter where I put it. I even tried converting the hair to editable geometry and it still showed up in the reflection. What am I missing?
Using C4D R20 with standard renderer. Hair Render is on in render settings.

can’t tell without the scene file – here the hair is reflected with a Compositing tag with Seen By Reflection turned off but once Generate is set to Flat, Triangle, Square or Circle (and I assume Instance if you provide one) the reflection disappears.

I tried that, and the hair seems to disappear from the render entirely when I do. I have attached the scene file. When I then try to make the object editable, the hair changes direction (??) and becomes visible again, but also appears in reflection. Very confused.
Here’s a link to the test file: https://www.dropbox.com/s/v3yas9w2awa7jhg/Grass%20Test.zip?dl=0

Your object is on a Transparent Plane.
You need to :1 Generate a geometry for your hair (Flat, square or so).
2 Because your hair has a geometry now, you need to Unchild the hair from your Transparent Plane to Avoid the transparent material to be
applied to the hair.
3 Go to your Compositing Tag >> uncheck Seen by refraction (because of the transparent object).
4 Go to your Compositing Tag>> Exclusion >> add the Water Plane here.
Hope that helps.
Good Luck
Imagination is the best tool…

That solved it, thank you!
