Opacity Problem

Hello, there is a problem that appears only when the project is exported.
If I play my project from the editor, everything works OK, and my opacity maps are cropped correctly. In this case, I use a black and white map as a mask to simulate tree shadows on the ground.

But, if I now export my project, without having touched anything, a problem occurs, and my shadows look tinted white

can you help solve this?

I could be this issue: Weird Eyebrows when Project downloaded and published on server

Yes, the problem is solved by changing “Alpha” to “Premultiplied Alpha”, but the editor has a problem, since when previewing with PLAY and being in ALPHA mode, it works OK, and when exporting it looks bad. Just so you keep it in mind
thank you
