Getting errors when rendering Procedurals (arnold scene source) in MAXtoA 2.3.37 3dsMax 2018

[Locutus666]

Some of my .ass assets stopped working when we updated MAXtoA to version 2.3.37 .
Those assets were made using MAXtoA version 2.2.956
If I disable abort on error, the geometry is rendered without shaders.

I tried to export those assets again and I still get these errors:

number of errors, error type:

8: [ass] line %u: %s.%s: unresolved reference to '%s'

number of warnings, warning type:

10: [ass] line %u: %s.%s: unknown '%s' parameter

3: [ass] line %u: %s: misplaced '%s' value

Does anyone know what are those errors?

Thanks,

Kyle

Scroll up in the Arnold log to see the specific messages.

Those are just a summary.

Looks like you're missing shaders used by the shapes in the ass files.

[nicola.stefano.jannuzzo]

What happened between those two version, is that we removed some of the plugin-specific c++ shaders, and replaced them by some factory Arnold nodes. So, my guess is that in your .ass files, you have references to those shaders, that won't be found by the newer MAXtoA.
One workaround you can try, is taking the MAXtoA_Shaders.dll file from the 2.2 installation, and copy it into the 2.3 installation (replacing the installed one).
