Hi Nicolas
I've heard that the bounding boxes are involved with the picking as
well. However, I don't know how to associate that with my problem. The
funny thing is that some area picks fairly well (the bottom stand),
some part is just ridiculously hard (Everything above upper part
rotated rotated in certain angle).
In fact, I also realized, if I rotate the model in a certain angle,
the picking works like magic, everything becomes pickable, but when I
rotate to another angle, the picking stops working. If I rotate the
model to the top of the bird's head is facing the camera, the picking
works well. If I view the bird from the side, only the stand works
well or sometimes other places can work too.
It is highly possible that the incorrect bounding box is the issue,
but I don't understand how the bounding box and picking works as a
whole.
My Chrome works fairly well. I'm using 7.0.503.0 version.
Regards,
Dave
