Hello, I'm new to Houdini and now following the tutorial for rendering the fractal. In the middle of the video, it uses arnold light in the object tab, but when I tried to search for it, such light doesn't exist. Is it not supported in free version?
Or Am I in the wrong place or tab to find it?

Hi,It looks like your Arnold renderder not installed correctly, If Arnold works in Houdini , there should a Arnold menu on the top next Help menu.
