hd in Vizard3.0

[mjabon]

Hello. When I run my old code from Vizard 2.5 using the hd with just
these simple lines:


import hd


box = viz.add('box.wrl')
hd.add(box)


The program crashes, with the error:


** ERROR: Failed to load plug-in: 'hd2.dlm'
Loading File: box_textured.wrl
Traceback (most recent call last):
File "<string>", line 11, in ?
File "test.py", line 22, in ?
** Load Time: 0.73 seconds
Scaling image 'beige.jpg' from (120,120) to (128,128)
hd.add(box)
File "C:\Program
Files\WorldViz\Vizard30\python\hd.py", line 244, in add
node._hapticID_ = _hd_.get()[0]
IndexError: list index out of range"



Now I can solve the problem by simply copying and pasting the hd.py from
the python folder in Vizard2.5 into the python folder in Vizard3.0. Is
this an error in the hd file? Should it be replaced?


Thanks!
