Thanks guys for all the help. Got through my show smoothly and it work out all great for me.

Just some thoughts and questions.

1) I tried applying a 3D object into my mix but I realised that there is no way I could rotate my 3D object. The rotation in the mix only allows you to rotate the images in the object. Can we have the rotation feature for 3D objects in mix?

2) Beside the 3D model topic but I realised that I could changes my artnet in universe to the prefered universe I want to patch. The default patch is starting from universe 0-3. Is there any way I could change that?
