Use Particle System for grass trail

I am working on grass which bends away and I had the Idea to create the trail with particle. I created a collison around the player but now I want to now if there is a way to use the particles which follows the character for the collison like the MPC because with the particles I could get a smooth trail animation. I thought maybe with Render Target but I dont now how this should work. Do have anyone a Idea how this could work? Thank you in advance!

You are on the right track. You need an orthographic scene capture, that would render only particles from top down.
The camera should be at constant height, and following the player by snapping in increments equal world size of capture render target texel.
