How to use LPE tags to isolate object's transmission?


Recommended Posts

I've gone through the LPE docs but there's still some context missing in my brain. This is all easy with lights, but trying to isolate the transmission/refractions of my background replies some syntax which I can't figure out based on the examples. I made an LPE tag for the cyc, and set up two extra render AOVs, both type color4f, with the names:
lpe:C+`cyc`L
lpe:C<T>+`cyc`L

The planes show up in the render, but they're black, so I'm clearly doing something wrong. What am I missing?

My simple dummy test project is attached.
