I have a setup where all the parameters of my HDA are being driven by work item attributes using the special attribute arrays in PDG -
hdaparms_floats
hdaparms_ints
hdaparms_strings
hdaparms_buttons

However there doesn't seem to be any way of driving ramps parameters or even color or vector parameters from work item attributes or am I missing something?

Thanks for any info here!

Thank you! but I was looking for a way to feed them into an HDA Processor like how you can use them to drive node parameters. I haven't been able to find a way without parsing them out with python though.

The HDA processor will automatically read work item values into drive the HDA if you write their names in one of the three arrays such as -
hdaparms_floats


But no sign of a way to drive them from a dictionary insteady.

In 20.5 it looks like a lot of support for dictionaries were added which seams great but I'm trying to figure out how I can have a dictionary attribute drive the parameters of an HDA processor. Seems like it should be possible but I can't find documentation or examples.

Anyone have any ideas?

Thanks so much!
