Hi Haroldo,
I too had the same kind of issue with VRML models and
I figured out a way try this:
If u want to detect the collion on the BranchGroup of
VRML model set "setAlternateCollisionTarget(true)" on
that BranchGroup. Important thing is USE_GEOMETRY on
the collision wakeups.
I have a moving platform. I add a child cube to the TG
that has ViewPlatform. I apply the collision detection
on this shape(CUBE).
If u do "setAlternateCollisionTarget(true)" on the
VRML BranchGroup get the collisions on this group
otherwise the shape in the SceneGraphPath.
BOL
Sivaram.
