Hello, I am testing digital extension with unreal engine asset.

I am using LED Walls and since the inner frustum has its own cam properties like focus length... etc, I need to calibrate the frustum with digital extension part.

However, since my asset is not located exactly at (0, 0, 0)(the center of my asset is (76.87, 5.90, -9.46)), I keep failing to match a frustum with the cooked asset. 

I found out that it is because of the rotation axis. Since the rotation axis is fixed on (0, 0, 0), while trying to rotate my asset, it doesnt rotate to the exact angle I want. 

Is there any other way to locate the floor to where I want? I googled it but couldnt find any solution for this. 

Best regards,

JM
