How to make decal on water surface?

I have been at this all morning and my decal goes thru the water plane and land on the terrain below every time. I’m using the translucent water plane sample. I cannot get my decal to apply to the water surface. is this not supported. I know it works in Cryengine. Has anyone done anything similar to the floating debris decals in cryengine?

I can’t get it to work testing it now. I remember having issues with decals on glass too. Might not work b/c of deferred rendering. I don’t understand it 100% but I know that transparency is the big downside. Might not be doable in the way we’d want, but doable in other ways, like all in the water shader? Have you seen any decals on glass? however that works might be the way…

found this but no answer
