S.P. ID mask: white border - antialiasing?

Borx25

I have a white line where two materials meet and I've tried adjusting the tolerance and hardness of the id masks but no luck because there's a point where if i increase more the tolerance the materials appears on places it shouldn't and hardness doesn't seem to fix it either. So, i'm thinking it's due to antialiasing, is it better to bake ID without any antialiasing?

is it better to bake ID without any antialiasing?

Yes; having AA in an id mat will cause issues.

Thanks for the answer.
Was hoping there was an alternative, because then you can't bake them all at once... Would be nice to have the AA setting on each map.

most of the time I create black and white mask out the id map. So if something is on top of something else I have no AA issues.
