Hello!
I am currently working on a project wich requires me making a 2D water plane and waves. I tried to make a displacement map on a 2D sprite but it yelded bad results so the waves, the sky and the sea floor are all in the same material. I tryed to sync the sinusoidal wave generation with one in the blueprints but without any satisfying result. I am trying to get the same thing as here but in a 2D world. This tutoial is kinda bad because it does not tell how to actually capture the image. What I would like is kind of a ray tracing that gives back a color that has been generated by the material.
I want to use as less c++ as possible since I am not verry experienced, so if you want me to code something, please tell me wich classes to use 
and what input and output (cause of the pointer thingys that are not there in C# and java where I used to code). I als noticed a cerain inaccuracy in the world position when rendering the material on a super scaled sprite if you have any Idea how to solve it please tell me too.
Thanks for your help,
Wicpar.
