Adding leafs and other details on roads

Hey all, what's the best practice of adding decals onto roads? Patches of leaves on a road for instance, or cracks here and there. The road follows the terrain so it isn't flat. So adding planes with a transparant texture won't work.

I've been looking into decal assets but I have no idea what asset is the best for what I need. Any tips you guys can give? Thanks!

 

I think? can you blend leaves onto terrain with texture2dArray inside your shader using pre-mult

Terrain.out =

terrain_input * (1 - (saturate[50*leaves.rgb]) + leaves

author leaves scatteted on black and dont paint darker then rgb 6,6,6


If you make progressive densities you could probably blend them using another swatch.r to lerp which density in the array

I _think_ this is possible.?
