How works gobo light in 3D Max

[saul.es]

I have seen a video on the youtube channel "arnold render" about how the gobo filter light works but I have only found the maya tutorial and other chales apply it in C4D.
But in 3D Max it is very different and I can't get it to works

The Arnold Gobo Filter only works with SpotLights

If you want to use a Quad light, you can copy the same texture to the Color -> Texture and set the spread to 0
