Hi Abentley,
welcome to the coolux family!
You have to create your object at the exact same parameters as you have in real.
You have to know the distance of your object to the projector, the angle of the lense, and all this surrounding parameters. If you create your object like this, you have to do nothing inside Pandoras Box as these parameters are the exact picture of your real setup.
This is why it is sometimes easier to warp directly with the 3D authoring tool on the object.

Hope this helps
