Question about Arnold operator expression (Set Parameter) Nov. 29, 2022, 4:59 p.m.
A whole year later I'm attempting to answer your questions, hopefully you found a good work-around for your problems.
The visibility in operators is a little tricky, the best resource I've found is here
https://arnoldsupport.com/2018/11/21/backdoor-setting-visibility/ [arnoldsupport.com]
I created an OTL to do the math for me. There's a line of python code to add up the different rays to the proper numbers. & then inside I set "visibility" to this calculated value.
Python code on the parm "calc"
I hope this helps

deep layer names not consistent with channel names in Nuke April 4, 2016, 8:34 p.m.
Just ran into this recently! When you read the deep render into nuke both .red and .r channels would be created; contaminating the script.
You need to remove the AOVs from the DCM, and then everything should behave properly.
As far as fixing your contaminated scripts… text editor or a filtering script to remove extra channels.

How do I import a MAYA FILE without losing the ANIMATION? May 9, 2011, 6:25 p.m.

this link has a bgeo exporter for maya.
OR you could google to see if you can find a script for exporting an .obj sequence (i remember there being a few of these online somewhere)
OR you can take a look at your fbx exporting options. Somewhere in there you can export animation, but i cannot remember exactly how. I think there is a check box which says “animation” that you need to turn on.
