turning off decals on landscape grass type

I have my grass laid down using Landscape grass type. But i dont want decals to render on the grass only the landscape under it, i cant find any way to turn this off unless object is a static mesh and placed in the world. Is there any work around for this where i can turn it off in this static mesh or in the grass type.

Thank you!

Hi Scampbell,

Currently this isn’t support that I’m aware of. I’ve gone ahead and entered a request for this to be added. For reference the ticket number is UE-26669.

Thank you!
