For the design of the nodegraph it is possible to add simplification options with possibility:
-to create or not the links of groups and components
-to create or not scatter links
- create only the display of the existing proxies
- to create or not layer
It requires display options, personally, I use the TIG plugin (a color sketchup = a material on Octane). I do not need groups and components.
