Physical Materials, not returning from Get Hit Result Under Cursor By Channel on Landscape

Hello CharlieTheTall,

I have a bit more information that I need from you in order to narrow down what is causing this.

1.) Can you recreate this in a new clean project?
2.) Does this happen in another version of the engine?
3.) Could you link me your DxDiag?

After I have this information I will attempt to recreate this issue on my end.

Thank you,
