How do i create an ink trail

Hey guys I am creating a game that leaves behind a trail on ink wherever the player goes. How do i get the ink to be printed and stuck on anywhere on the terrain? I tried using Trail renderer and particles. But trail renderer doesnt leave a flat texture on the terrain and I cannot seem to use shuriken particle’s system to get its particles to face up when it collides with the terrain.

Thanks for your help!

Did you look to see how the tyre skid marks are created in the Unity car tutorial? Sounds similar to what you’re trying to achieve.
