Processing a block of pixel from a texture
I have a black and white texture ( full HD ) and I want to break it into custom number of rows and columns. After that I want to calculate the average amount of pixel values per each block. Since the texture is big it uses a lot of time for C++ to do it and I thought maybe there is a way to do it via GPU (ue4 metrials).
My question is that : how do you break a texture to for example 16 columns and blocks using materials ? additionally I don't know how to make an average of a group of pixel. lets say you have 200 pixels and you want to get the average of their alpha channel.
