Any curvature like overlay shader?

It’s hard combining different shaders right now unless you know how to write them, which i don’t cause I’m stupid

i think i got most of the desired effects together but I’m lacking a sole curvature effect (tv curvature like shader)

is there any such shader or overlay? that works on top of something like scalefx

Unfortunately, if you add curvature onto the end those sorts of shaders, you’ll get some pretty nasty aliasing. The curvature needs to be built into the scaling process, but if you try to bake it into a smoothing shader, like xBR, it will cause issues with the edge/corner-detection algorithm, which leads to messy, jagged edges.

I’ve tried to do the exact same thing and like hunterk said it is not that easy. You usually get a moire like affect which can be a pain on the eyes, or bad aliasing. If you are looking for a good curvature shader I recommend CRT-Lottes. It looks great on all systems, though kind of blurry, but that can be removed by using multipass and removing the filter.
