I’d like to displace the vertexes of a static mesh with the “World Positon Offset” function, but I am having a hard time getting it to work. Could somebody possibly share a screenshot of a simple material that does this properly?
Take a look at this tutorial: Unreal Engine 4 Tutorial: Wind Effect (english) - YouTube
Or you could load the content examples project and open the math hall level. The first example on the right shows WPO to fake a bouncing ball by taking the ABS of the Sine of time. It is about the simplest case you will find.
