HDRP Decals Artifacts

Hello !

My problem is that any decal that affects emission leads to unwanted outlines : any object that is on top of the decal has an emissive outline even where the decal shouldn't be affecting materials, as you can see there :

Is there any easy way to fix this ? I rely a lot on this type of decals, and that looks terrible...

Thank you !

 

I think this is not only an emission problem.

It is general problem with decals, please take a look at my topic:

Obviously it was not addressed by anybody.
So I might say that decals in hdrp are just not working correctly.
