Hi all,

I'm attempting to write a particle cache exporter and I'm having trouble getting the Python module to use functions that are stored in a different section.

My instinct was to create a new output driver type as the category made sense, but there were a few challenges which I'll mention here for others facing the same issues:

The ‘Render to Disk’ button's Callback Script section is greyed out. To run code when this button is pushed you need to 

1. Create a file parameter called ‘soho_program’ and change it's default channel value to ‘opdef:.?PythonModule’
   
2. Create a file parameter called ‘soho_outputmode’ and change it's default to 2
   

This just runs the code in PythonModule. I have another module in which I store the functions that need to be run in PythonModule, but I cannot import these fucntions. The docs about asset modules [sidefx.com] state that you need to write the following to import another section as a module:

However, because this is an output driver, there appears to be no kwargs argument, so I cannot get the kwargs value. I've tried other methods such as hou.nodeTypeCategories(). Strangely the ‘Driver’ type is not available directly like all the others are as listed here [sidefx.com].

Does anyone know how to import modules from the other sections when using the Driver type?

Ok, I'm just stupid. I'm not sure how I didn't try this before my lunch break, but to get the type when you do not have access to kwargs, just useSo the code from the previous post should read:
