Hi. I'm begginer of poser.
I need your help.

I made poser file.
But there are too much cameras.

Can you delete cameras?

You can download the file.

Please help me.

I looked at the PZ3.  Actually, the cameras are correct. 
Poser always creates one "Shadow_cam" for every Light.
You have 12 Lights, and 12 Shadow_cams. 

This makes the camera list long, and hard to work with ...
but there's no good way to avoid it.  

Just ignore the shadow_cams.... they aren't very useful anyway!

I see.
Thanks to ockham.
