Hi Gordon,
In Creator/OpenFlight, the defaults for all the DOF min's and max's are all
0's and the step values are all 0's
and of course the scale current is set to 1,1,1
OK then the values that are now set should be correct (since the default
ctor for Vec3 sets it to (0,0,0) ).

To me that seems a rather bad default to have for scaling on a DOF, I would
have assumed the default would be 1,1,1 not 0,0,0
Is there a reason why its 0,0,0, and not 1,1,1 and should we change it

Dear Brendan,
That was absolutely the problem!! Thanks so much for your help.
Sincerely,
Oren
p.s. I wish there was some kind of heads-up in the header file for
DOFTransform!!

Hi Oren,
This mightn't be your problem, but for some reason the default scale for an
osgSim::DOFTransform is (0,0,0). This is what I usually forget when using it.
Cheers,
Brendan

I've managed to insert DOFTransform nodes into my model but the geometry under
these nodes are not being drawn even though the drawable update callbacks are
definitely being called...
The weird thing is, if I replace the DOFTransform with a simple
MatrixTransform, the geometry renders
wow, thank you guys for the great help... DOFTransform seems to be right on the
money.

Hello everyone! Here is my question:
I have a model of a sea faring vessel that has little gadgets on it like
radars, turrets, propellors, etc. these gadgets are fully contained in separate
named Geodes. That means that the geometry in the geode is specified relative
to the origin of the ship a
