Hello 
I’m working on https://threejs.org/examples/?q=fra#webgl_framebuffer_texture 's code
I have main box object which I want to apply orbit control to overlay div.
and I added cone object relative to box object which I want to apply dragObject.
but when I tried to do so, dragStart callback function is not called.
it’s because I’m touching overlay.
is there a any way that I can use both of them?
full code snippet is as belows. (generating function is called when I press button and generating cone to box object and I want to drag that cone)
