In an attempt to accomplish a gaussian blur for my UI like in this screenshot:
I need to use the scene color from a UI material, which isn’t possible as far as I can tell. Can I use a SceneCapture2D as the only camera in the scene so that its only rendered once and not twice, that way I could just draw the render target to the screen and access it inside the UI material and do the blur there. Thats the only way that I can think to do it other than changing the engine code to allow me to copy the scene texture into another buffer or putting a blurred version of the scene into another buffer using depth of field (which I’m already using to do a full screen blur).
Are any of these at all possible? I don’t mind modifying the engine source code, but I took one look at it and had no idea where to even start.
