Whats the easiest way to blur a texture sample?
I’m currently using a render target texture sample to mask out some areas of my level. It works well, but in order to get the desired effect, I need to ceil the texture sample and then invert it to be used (so all pixels are either 0 or 1). Ideally I’d like to soften the edges after the ceiling of the texture sample where it goes from white to black, but how to do this seems to be escaping me. I know of Spiral Blur - Texture but that only works for a texture object and I don’t think I can use that in this case since the UV’s of the texture sample are heavily modified(?). Ideally I’m looking for something along the lines of a feather operation in photoshop, but it also needs to be fairly efficient/quick due to this being used at real time and render target updating quite frequently.
