I doubt anyone will be able to help given the information. You are diving
into providing snippet of code and a screenshot with almost no context.
It's far better to take a step back and explain what you are doing with
your application from a high level to give the context, then explain what

You can't expect people to help you when you don't explain the problem you
are seeing. A title, a screenshot and some shader code is not in any way
sufficient. Far better to take a step back and explain what you are doing,

Is there a problem with adding or removing OSG nodes directly in the Qt
Widget events?
My idea is to send OSG USER events to complete the operation of adding and
removing OSG nodes.

When you saying volume what do you actually mean?
The models that are loadable from .obj can be totally unconstrained open
meshes where a volume isn't normally applicable without extra constraints.
Do you know your models are manifold geometries?
