the RenderAction RA excludes a node N and its subtree if
(RA->getTravMask() & N->getTravMask()) == 0.
For volume calculation only nodes with N->getTravMask() == 0 are excluded.
Choosing the following:
RA mask: 1
excluded Node mask: 2
should do what you need, the node has a mask different from 0 and it is
not visited by the RA.
Hope it helps,
Carsten
