Anti-aliasing in Scene component 2D

I need to anti-alias my render target that I’m using in material to make the background transluscent and show it in widget. As I know Anti-aliasing works only with final color and I can’t do that, because I have to have my Alpha chanel to cut out the background.
I read a lot of topics about this and all of them seems to be unsolved or unanswered, but maybe somebody knows the solution or some workaround with distance field or smth?

add a half pixel offset to the uvs, so… the texture filter samples inbetween and “blurs” the edges.

How can I do that? I’m sorry, I’m new to this.


I did something like this, but it also doesn’t seem to work

well… you gotta compute the half pixel offset. something like this…

but… it doesn’t work as well as i thought it would. (maybe for lowres rendering.) so… you gotta wait for somebody with a better idea.
