ndisplay: how to match player input with camera view?

hi developers,

basically i have 2 monitors set vertically from each other, and i set the viewport of ndisplay with the in-game cameras. In order for the player to interact base on the viewport, i blend the top camera to the player controller as a test. The expected behaviour is to only be able to interact with the object within the top camera. However, what happen is where i click on the screen does not match where the raycast is.

i am drawing the raycast by using “ConvertMouseLocationToWorldSpace”.

Have you solved this issue?
