Hey!

I checked the incorrect light expression in a Render Var and it does not crash for me. I get an error message in the terminal about an incorrect light path expression, and nothing is rendered anymore. Fixing the LPE resumes the render.

Can you tell me your OS/Houdini version/HtoA version?

no errors, the whole houdini session collapse into the void in a millisecond.
