如何在UE4中创建亮度slider

[英]How to create a brightness slider in UE4

I want to create a slider that can adjust the brightness of a game in Unreal Engine 4, but I don't know which module to use in blueprints to adjust brightness.我想在虚幻引擎4中创建一个可以调节游戏亮度的slider,但是不知道在蓝图中使用哪个模块来调节亮度。 Which blueprint module should I attach to the module for the slider's value change?我应该将哪个蓝图模块附加到模块以更改滑块的值? Should this even be done in blueprints, or should I do it in C++ instead?这甚至应该在蓝图中完成,还是应该在 C++ 中完成?

You could try a post-process actor, and change its brightness value via blueprint您可以尝试后处理演员,并通过蓝图更改其亮度值
