Two transparent materials bleed into one

In fact, I do use two-sided Thin Translucent with Forward Shading, yet it still do that ugly thing.

Now, with that being said, could you, please, show me some functional masked material example with opacity graph into a DitherTemporalAA node and that node into the Opacity Mask input? As I have no clue whatsoever how to do that…

This is how my material looks, and underneath I attached ZIP with the actual .uasset for you, so you can post your masked material mod if you will, hm?
