Hi Mark,
Node masks aren't inherited down, they are checked on each node as the
traversal decends, so if you switch off a top level node then none of
its children are traversed.

Hi,
I have some legacy openflight models that I wish to use in my app. Within
the models there are nodes that I need to switch on and off. Fortunately the
nodes have a naming convention that allows me to find them. However they are
not switch nodes. I have set the node masks something like the following
Instance1
-----------------------gear 0x02
\ |
\
|----------------------engine_on 0x04
\ |
Instance2
------------Aircraft--------|----------------------engine_off
0x08
/ |
/
|----------------------engine_afterburner 0x16
/ |
Instance3 |
Etc, etc
Now my question is, do the lower nodes inherit and then AND the node mask
from Instance node? As what I would like to do is switch the various lower
nodes on and off by just setting a single node mask at Instance such as 0x06
which would give me gear and engine_on everything else off? Obviously I need
a mechanism that has individual masks for each instance as I do not want all
instances to necessarliy have gear and engine_on.
I have tried coding this but don't get the results I would expect. I have
searched around and not found any examples or hints on how to do this. Am I
misunderstanding the use of Node Masks, and/or is there a betterway
Thanks in advance for any help/suggestions
Cheers
Mark
