Oh and sorry, here's the doc info on masks and why I chose to follow
ai_node_entry to query the int values. You'd do some sort of look-up dict
that was pre-set to check which button is going to give you which
ai_node_entry value and you're better off querying as the ai_node_entry
since if arnold randomly decides to change it you have better futureproofed
code. Either that or just make sure to name the buttons after which node
which you could query a little more dynamically like this but it's a little
hackey:
(let's assume your buttons have names like 'AI_NODE_ALL' and the label
could be "all objects" or something and I'm assuming that the mask value is
just adding all the object mask ints together...)
mask_val = sum([arnold.ai_node_entry.__dict__[button.name()] for button in
buttons])
*mask*: specifies which Arnold node types are included in the .ass export.
See the AtNodeEntry page of the Arnold API for the available node types.
