I have an actor which holds an array of floats that I want to render out on a plane somehow (values close to 1.0f are green, values close to 0.0f are black, values in the middle are pink etc). Effectively it is a height map but the data changes every frame.
I originally tried to use DrawMaterialToRenderTarget. This works for changing a few pixels but of course grinds to a halt if you try and update an entire texture (which I should have seen coming!).
Is there a method to achieve what I am trying to do?
