Ray Trace Shadows: Light Radius (multiple lights)

I was wondering if there is a way to edit the light radius attribute that resides inside the ray trace shadow tab for several lights at the same time. I have a scene where i have several lights and its a pain to edit each one separately.

I already tried using the attribute spreadsheet but that specific attribute is not available there. Not sure why though...

That Attribute should be in the AttributeSpreadsheet, but I think what you're seeing is the Transform Node's attributes in your spreadsheet, not your Shape Node's.

Select your lights in Outliner, then press ↓ on your keyboard. This will select their Shape Nodes only. Now open your AttributeSpreadsheet, click the "All" tab up top, and scoot to the right until you see "Shadow Rays" and "Ray Depth Limit". "Light Radius" is just a few more over to the right, just left of "Cast Soft Shadows". See Screenshot.

Hope this helps! It may only work this way if you do each type of light separately. That is, if you have a bunch of point lights and a spot light, you may need to do the spot light separately, or vice versa. Not sure, but good luck!

Oh man... I was one keystroke away all this time. Pressing down on keyboard now displays it on the attr spreadsheet.

Thanks!! You will save me a LOT of time!
