Curtain Effect is sideways

[Greyfox]

Hi there. When using the Curtain Effect the visualization is facing to the right but the curtain edge is set to center. Confused as to why its not facing me as I look at the screen. Using some swag and I see the effect working but it faces out to the right side of the screen so I get a side preview of it opening and closing properly. Can I change a setting so the curtains open facing me as I look at the screen. Using  Tree 360 degrees Wedges bottom left. Confused

How many vertical strings are in your tree? I tried on a 16 string tree and the center of the curtain effect is just to the right of front center.
