Hi Jonathan,
There is a couple of Capability not set correctly. Attach
is the file which fixed the problem.
Besides, there is a bug in Java3D which output
misleading capabilibityNotSetException message
"Node: no capability to read Pickable"
instead of
"Node: no capability to read Collidable"
when ALLOW_COLLIDABLE_READ not set.
Bug 4730461
- Incorrect capabilityNotSetException message output for Node.getCollidable
is submitted for this.
Thanks for your bug report.
