Hello! Recently while looking through the Karma Fog Box node I stumbled upon a Karma Ray Import node with a variable "ray:isshadowray" - This variable is not written in the official list provided on the Houdini help page/inside the node menu - I was just wondering if there are any other unlisted ray import variables, and if it is possible to access the full list somewhere.

Would be interested in knowing this too.

The documentation lists the available rays for import, don't know if this is up to date.

Hello! Just to update the post, seems like ray:isshadowray and some other variables have been added to the help page after the last update, so it's probaly up to date now. Thanks for the help!
