[Maya-API] MpxFielnode - Custom Field node and how to access the volume control

[MicheleA]

Hi there, 

Working on a custom field, and I was trying to find in the class documentation and online for example on how to use/access the volume control attributes.

Is this even possible or i have to create my volumes from scratch and forget about it?

The examples provided in the doc (like torusField), doesn't really help in this case. In fact the torus is just an openGl draw that is not affecting at all the filed.

The funny part is that those attributes are always there no matter what, which I need to clean in the AETemplate, but there is no visible way to use them (or better I should say I don't know how)

Anyone tried to do something similar? Any idea?

Many, many thanks in advance!
