Disable Anti-aliasing only for 2d Sprites


My game is combining 2d and 3d, and in order to avoid getting fuzzy edges on my sprites, I need to disable all anti-aliasing in my Project Settings. Problem is, it disables it also for my 3d objects, which is undesirable. Is there a way to only exclude the anti-aliasing for my sprites?

Thanks in advance!

Did you get any ideas to do it? I have same problem with you
