Hello, i have this strange issue, when all decals in the project are half trasparent for some reason (even the ones with default material). How to fix it?
Well, I’m not sure it will matter, but all of the decals in your screenshot are pointing the wrong direction. See that tiny white arrow? It should be pointing away from the surface, rather than into it. If you have it facing the wrong way, you’ll get inverted normals and potentially wrong colors.
Next, there are several things that affect decal opacity:
On the material, the Color next to the Base Map has an alpha channel which will affect transparency. Also on the material the Global Opacity affects opacity.
And on the Decal Projector, the Fade Factor affects transparency:
Omg, that was it! I must’ve been so sleepy when i decided to checkout how decals work, so i absolutely didn’t noticed that parameter. Thank you so much!

The arrow has to be pointed at the surface, what are you talking about?
Whoops, you’re right. I edited the post to omit the error.
