Unity HDRP Terrain Trees not working ! Version 2019.2.8f1,Unity HDRP Terrain Trees not working Version 2019.2.8f1

I have been trying to paint grass using unity hdrp terrain system. This is not supported yet, but as a workaround a lot of people use the tree system. Problem is, nothing appears for me when i add trees / grass. So far i placed the trees by hand, but for the grass that's just too much, and other external tools for object scattering that i've found so far are also not working. I do not get any errors in the console either.

Any idea why I can't paint objects in unity hdrp through the tree system?

Are there any other workarounds for this?

For now i created a mesh out of the terrain as a double and use polybrush to scatter objects but that s way to slow since it does ot scatter enough objects at the same time. I'm on a deadline so any help would be really really welcome :( ,I have been trying to paint grass using unity hdrp terrain system.
