I am new to the SideFX community, I am not sure if anyone has asked the similar question before, but I could found it by use forum search. I am trying to use Arnold set parameter to define the object, I could not find the exactly example.
I tried type expression like the image I attached, it doesn't work. However, I type visibility = 0, this works, but this is not the result I wanted, I wish to use Arnold shape parameter. could anyone show me what is the correct way to do this? Thanks very much
