[Closed] ParameterBlock inside a parameter block

Hi,

I think I know the answer to this, but is there a way to create a sub parameter block inside a custom plugin?

Like if i wanted to break my properties down into more or less classes/categoreis.

for example:

 Material
       ->   Display
                 -> Visible

      ->     Properties
                   ->Color

Right now it puts all the properties in 1 level. I know i’ve separated before using custom attributes, but then its a fine dance of making sure the custom attribute is unique per material, and the settings get passed on recompile
