Wow, guys… no answers? Is this that difficult or even unknown? In another engine that I’m not mentioning to avoid starting the usual ridiculous debate, I can do it with just 2 simple lines of code without impacting FPS at all:
myTexture.LoadRawTextureData(myPixels);
myTexture.Apply();
There has to be a UE4 equivalent for it! I can’t believe it’s not there at all
