The detail settings work fine, but with this kind of mask/blood decal texture and the different blend modes, I only got the results as in the posts above. The blending is not the problem, but to get the red color to the blended areas.
I became aware of the idea with transparency at the beginning, but I hoped it would work via masking. Now you mentioned the transparency too, so I finally decided to give it a try.
I edited the blood decal texture and converted the black color to transparency and colored the white parts in red (I took the blood color from the base texture which is an atlas texture).
Now I have the following setup for the main material:

And the result looks like this:

The blood splatter at the womens head bandage is the original color from the base texture, not from the details (only for comparison).
This will work for me at the moment (and worked with a dirt detail texture too that I used for other things). Now it is an already precolored simple overlay texture.
Again many thanks for your help.
Cheers
