Hello, I have a problem with unreal engine 4.6.1. The problem is whenever the mouse is held down the entire screen goes white, I don’t mind the flash when I click on the screen, but whenever I run my game in Unreal Engine build in gameplay tester the entire screen goes white!!! Is there anyway I can gameplay test my game outside of Unreal?? If so please tell me!
