the op defined in 'options.operator' is not an operator node

[slyFKGGM]

Hi everyone!

I am trying to render a sequence using the new operators for dynamic shader assignements. It works just fine locally in interactive and also on the farm if the job is sent as a mayaBatch job.

But if I try to send as an Arnold render job, the shaders are not applied (render white)

I've found this error along the way digging in the logs.
"the op defined in 'options.operator' is not an operator node"

The node plugged in the render setting is an aiMerge node with 7 aiSetParameters nodes plugged in.

Does anyone else knows about it?

Thanks a lot!

Can you post the options.operator line from the ass file?

That message means that options.operator has the name of a node that exists, but that node isn't an operator.

Hi Steph

hmmm I Did not found options.operator in the ass file... I got this tough:

operator "aiMergeOperator2"

thanks!

[Stephen.Blair]

Ok, that's the line. I should have said "the operator line from the options node"

If you search forward in the ass file for aiMergeOperator2, do you find this?

merge
{ 
 name aiMergeOperator2

[slyFKGGM]

This is from a fresh operator graph:

operator "aiMerge2"

||

merge {

name aiMerge2

inputs 7 1 NODE "aiSetParameter_body" "aiSetParameter_tongue" "aiSetParameter_sclera" "aiSetParameter_teeth" "aiSetParameter_pupil" "aiSetParameter_meniscus" "aiSetParameter_iris" }

Does this fresh one also trigger that the op defined in 'options.operator' is not an operator node message?

I think you may need to send us a repro scene, or the ass file. You could export everything except the shapes and shaders, and send that ass file.

[slyFKGGM]

Yes it does!

Okay will share the ass in a couple of minutes!!

thank you Steph!

The main problem was that the ASS file was exported with Expand Procedurals enabled.

Because of that, selection expressions like aiStandin*/*Shape* did not work.

Solution was to turn off Expand Procedurals
