after playing around several hours with the TEveGeoTopNode class, I have reached an impass:
I am trying to set the whole root geometry as it is contained in the top node to one color and transparency setting. However, anything I do on the top node leaves the rest untouched (which makes kind of sense). I can see in the geometry scene of Eve that there are TEveGeoNode objects for the sub-components somewhere, but I failed to gain access to them.
Has anybody an idea how to accomplish that?
