What's your plugin version? I can see the filter in that menu on my mac.

[ronghe_dai]

thank you:) the version is 2.3.0.

Maybe something is wrong with your installation? The toon shader appears fine, right?

[ronghe_dai]

yes, no problem with the toon shader appears at all. I installed twice in last week but nothing helped with the problem. it's so confusing.

Also it would be interesting to see if the filter is listed when you run kick from the command line (C4D_DIR is your Cinema 4D folder):

C4D_DIR/arnold/bin/kick -nodes n
