LPE to capture ID information

[am_wilkins]

Hi there,

I'm trying to setup an "LPE" to capture the ID channels / masks (from the shaders) in some reflections.
Looking through all the documentation I'm not seeing any examples of the LPE for ID AOV.
 https://docs.arnoldrenderer.com/display/A5ARNTUT/Introduction+to+Light+Path+Expressions 

https://docs.arnoldrenderer.com/display/A5ARP/Light+Path+Expression+AOVs 

Does anyone know if this is possible and what the LPE would be do capture this information?

Thank you!

Hello there,

Just bumping this thread as I've received no reply yet.

Hope the question makes sense?

I have a reflection that I need to capture some ID masks in as an AOV.

Would like to know if this is possible.

Thanks very much.

Sorry, but there's no such light path expression. There's just the ones listed on that page.
