Hi David
I tried using the info of the Mouse#devent, but doest work,Im tryn to
do this I have my 3ds exported is animal shape , basically I want to
do make click on the body and add a primitive exactly where I clicked
over the model, I tried using sceneX and scenY but witout success.
if found this old code that try to do this:
It depends on Away3D's MouseEvent3D which gives you u,v
> coordinates of the mouse click. This code then calculates the x,y,z
> of the mouse pointer in object space as a linear combination of the
> vertices of the face you clicked on.

I tried to translate to new version of Away but still is not working.
