jamalade Posted April 4, 2018 Share Posted April 4, 2018 Hello, New houdini user here.. hope you can help. I'm trying to use the Arnold utility node to query light levels on an object so i can drive the emission on a standard_volume shader. The utility node with 'color, lambert' into a standard surface seems to work fine but if i try and use a standard_volume and render a volume from my geo through Arnold, the utility node doesn't seem to work. Am i being naive trying to query light from a volume? ta Jam Quote Link to comment Share on other sites More sharing options...
